DIRECTIVE 97/23/EC OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL

of 29 May 1997

on the approximation of the laws of the Member States concerning pressure equipment



THE EUROPEAN PARLIAMENT AND THE COUNCIL OF THE EUROPEAN UNION,

Having regard to the Treaty establishing the European Community, and in particular Article 100a thereof,

Having regard to the proposals from the Commission ( 1 ),

Having regard to the Opinion of the Economic and Social Committee ( 2 ),

Acting in accordance with the procedure laid down in Article 189b of the Treaty ( 3 ), in the light of the joint text approved by the Conciliation Committee on 4 February 1997,

1. Whereas the internal market is an area without internal frontiers in which the free movement of goods, persons, services and capital is ensured;

2.

Whereas there are differences in the content and scope of the laws, regulations and administrative provisions in force in the Member States with regard to the safety and protection of health of persons and, where appropriate, domestic animals or property, where pressure equipment not covered by present Community legislation is concerned; whereas the certification and inspection procedures for such equipment differ from one Member State to another; whereas such disparities may well constitute barriers to trade within the Community;

3.

Whereas the harmonization of national legislation is the only means of removing these barriers to free trade; whereas this objective cannot be achieved satisfactorily by the individual Member States; whereas this Directive only lays down indispensable requirements for the free circulation of the equipment to which it is applicable;

4.

Whereas equipment subject to a pressure of not more than 0,5 bar does not pose a significant hazard due to pressure; whereas there should not therefore be any obstacle to its free movement within the Community; whereas this Directive applies to equipment subject to a maximum allowable pressure PS exceeding 0,5 bar;

5.

Whereas this Directive relates also to assemblies composed of several pieces of pressure equipment assembled to constitute an integrated and functional whole; whereas these assemblies may range from simple assemblies such as pressure cookers to complex assemblies such as watertube boilers; whereas, if the manufacturer of an assembly intends it to be placed on the market and put into service as an assembly — and not in the form of its constituent non-assembled elements — that assembly must conform to this Directive; whereas, on the other hand, this Directive does not cover the assembly of pressure equipment on the site and under the responsibility of the user, as in the case of industrial installations;

6.

Whereas this Directive harmonizes national provisions on hazards due to pressure; whereas the other hazards which this equipment may present accordingly may fall within the scope of other Directives dealing with such hazards; whereas, however, pressure equipment may be included among products covered by other Directives based on Article 100a of the Treaty; whereas the provisions laid down in some of those Directives deal with the hazard due to pressure; whereas those provisions are considered adequate to provide appropriate protection where the hazard due to pressure associated with such equipment remains small; whereas, therefore, there are grounds for excluding such equipment from the scope of this Directive;

7.

Whereas, for pressure equipment covered by international Conventions, transport and pressure hazards are due to be dealt with as soon as possible by forthcoming Community Directives based on such Conventions or by supplements to existing Directives; whereas such equipment is accordingly excluded from the scope of this Directive;

8.

Whereas certain types of pressure equipment, although subject to a maximum allowable pressure PS higher than 0,5 bar, do not present any significant hazard due to pressure, and therefore the freedom of movement of such equipment in the Community should not be hindered if it has been legally manufactured or placed on the market in a Member State; whereas it is not necessary in order to ensure free movement of such equipment to include it in the scope of this Directive; whereas consequently it is expressly excluded from its scope;

9.

Whereas other pressure equipment subject to a maximum allowable pressure higher than 0,5 bar and presenting a significant hazard due to pressure, but in respect of which free movement and an appropriate level of safety are guaranteed, is excluded from the scope of this Directive; whereas such exclusions should, however, be regularly reviewed in order to ascertain whether it is necessary to take action at Union level;

10.

Whereas regulations to remove technical barriers to trade must follow the new approach provided for in the Council Resolution of 7 May 1985 on a new approach to technical harmonization and standards ( 4 ), which requires a definition of the essential requirements regarding safety and other requirements of society without reducing existing, justified levels of protection within the Member States; whereas that Resolution provides that a very large number of products be covered by a single Directive in order to avoid frequent amendments and the proliferation of Directives;

11.

Whereas the existing Community Directives on the approximation of the laws of the Member States relating to pressure equipment have made positive steps towards removing barriers to trade in this area; whereas those Directives cover that sector only to a minor extent; whereas Council Directive 87/404/EEC of 25 June 1987 on the harmonization of the laws of the Member States relating to simple pressure vessels ( 5 ) is the first case of application of the new approach to the sector of pressure equipment; whereas the present Directive will not apply to the area covered by Directive 87/404/EEC; whereas, no later than three years after the present Directive enters into force, a review will be carried out of the application of Directive 87/404/EEC in order to ascertain the need for the integration thereof into the present Directive;

12.

Whereas the framework Directive, Council Directive 76/767/EEC of 27 July 1976 on the approximation of the laws of the Member States relating to common provisions for pressure vessels and methods for inspecting them ( 6 ) is optional; whereas it provides for a procedure for the bilateral recognition of testing and certification of pressure equipment which did not operate satisfactorily and which therefore must be replaced by effective Community measures;

13.

Whereas the scope of this Directive must be based on a general definition of the term ‘pressure equipment’ so as to allow for the technical development of products;

14.

Whereas compliance with the essential safety requirements is necessary in order to ensure the safety of pressure equipment; whereas those requirements have been subdivided into general and specific requirements which must be met by pressure equipment; whereas in particular the specific requirements are intended to take account of particular types of pressure equipment; whereas certain types of pressure equipment in categories III and IV must be subject to a final assessment comprising final inspection and proof tests;

15.

Whereas Member States should be in a position to allow the showing at trade fairs of pressure equipment which is not yet in conformity with the requirements of this Directive; whereas, during demonstrations, appropriate safety measures must be taken in accordance with the general safety rules of the Member State concerned to ensure the safety of persons;

16.

Whereas in order to ease the task of demonstrating compliance with the essential requirements, standards harmonized at European level are useful, especially with regard to the design, manufacture and testing of pressure equipment, compliance with which enables a product to be presumed to meet the said essential requirements; whereas standards harmonized at European level are drawn up by private bodies and must retain their non-mandatory status; whereas, for this purpose, the European Committee for Standardization (CEN) and the European Committee for Electrotechnical Standardization (Cenelec) are recognized as being the bodies that are competent to adopt harmonized standards that follow the general guidelines for cooperation between the Commission and those two bodies signed on 13 November 1984;

17.

Whereas, for the purposes of this Directive, a harmonized standard is a technical specification (European standard or harmonization document) adopted by one or other of those bodies, or by both, at the request of the Commission pursuant to Council Directive 83/189/EEC of 28 March 1983 laying down a procedure for the provision of information in the field of technical standards and regulations ( 7 ) and in accordance with the general guidelines referred to above; whereas, in relation to standardization, it would be advisable for the Commission to be assisted by the Committee set up pursuant to Directive 83/189/EEC; whereas the Committee will, if necessary, consult technical experts;

18.

Whereas manufacturing of pressure equipment calls for the utilization of safe materials; whereas in the absence of harmonized standards it is useful to define the characteristics of the materials intended for repeated use; whereas this definition is established by European approvals for materials, such approvals being issued by one of the notified bodies specifically designated for that task; whereas the materials conforming to the European approvals shall be presumed to satisfy the essential requirements of this Directive;

19.

Whereas, in view of the nature of the hazards involved in the use of pressure equipment it is necessary to establish procedures for assessing compliance with the basic requirements of the Directives; whereas these procedures must be devised in the light of the level of danger which is inherent in the pressure equipment; whereas, therefore, for each category of pressure equipment there must be an adequate procedure or a choice between different procedures of equivalent stringency; whereas the procedures adopted are as required by Council Decision 93/465/EEC of 22 July 1993 concerning the modules for the various phases of the conformity assessment procedures and the rules for the affixing and use of the CE conformity marking, which are intended to be used in the technical harmonization Directives ( 8 ); whereas the details added to these procedures are justified by the nature of the verification required for pressure equipment;

20.

Whereas Member States should be in a position to authorize user inspectorates to carry out certain tasks for conformity assessment in the framework of this Directive; whereas for that purpose this Directive sets out criteria for the authorization of user inspectorates by Member States;

21.

Whereas, under the conditions laid down by this Directive, certain procedures for conformity assessment may require each item to be inspected and tested by a notified body or a user inspectorate as part of the final assessment of the pressure equipment; whereas in other cases provision should be made to ensure that the final assessment may be monitored by a notified body by means of unexpected visits;

22.

Whereas pressure equipment will, as a general rule, bear the CE marking affixed either by the manufacturer or by his authorized representative established within the Community; whereas the CE marking means that the pressure equipment complies with the provisions of this Directive and those of other applicable Community directives on CE marking; whereas for pressure equipment defined in this Directive which presents only a minor pressure hazard and for which certification procedures are therefore not justified, the CE marking will not be affixed;

23.

Whereas it is appropriate that the Member States, as provided for by Article 100a of the Treaty, may take provisional measures to limit or prohibit the placing on the market, putting into service and use of pressure equipment in cases where it presents a particular risk to the safety of persons and, where appropriate, domestic animals or property, provided that the measures are subject to a Community control procedure;

24.

Whereas the addressees of any decision taken under this Directive must be aware of the reasons behind that decision and the means of appeal open to them;

25.

Whereas it is necessary to lay down a transitional arrangement enabling pressure equipment manufactured in compliance with the national regulations in force on the date of entry into force of this Directive to be marketed and put into service;

26.

Whereas the requirements laid down in the Annexes should be made as clear as possible so as to allow all users, including small and medium-sized enterprises (SMEs), to comply with them easily;

27.

Whereas an agreement on a modus vivendi between the European Parliament, the Council and the Commission concerning the implementing measures for acts adopted in accordance with the procedure laid down in Article 189b of the Treaty was reached on 20 December 1994 ( 9 ),

HAVE ADOPTED THIS DIRECTIVE:

ANNEX I

ESSENTIAL SAFETY REQUIREMENTS

PRELIMINARY OBSERVATIONS

1.

The obligations arising from the essential requirements listed in this Annex for pressure equipment also apply to assemblies where the corresponding hazard exists.

2.

The essential requirements laid down in the Directive are compulsory. The obligations laid down in these essential requirements apply only if the corresponding hazard exists for the pressure equipment in question when it is used under conditions which are reasonably foreseeable by the manufacturer.

3.

The manufacturer is under an obligation to analyse the hazards in order to identify those which apply to his equipment on account of pressure; he must then design and construct it taking account of his analysis.

4.

The essential requirements are to be interpreted and applied in such a way as to take account of the state of the art and current practice at the time of design and manufacture as well as of technical and economic considerations which are consistent with a high degree of health and safety protection.

1.

GENERAL

1.1.

Pressure equipment must be designed, manufactured and checked, and if applicable equipped and installed, in such a way as to ensure its safety when put into service in accordance with the manufacturer's instructions, or in reasonably foreseeable conditions.

1.2.

In choosing the most appropriate solutions, the manufacturer must apply the principles set out below in the following order:

 eliminate or reduce hazards as far as is reasonably practicable,

 apply appropriate protection measures against hazards which cannnot be eliminated,

 where appropriate, inform users of residual hazards and indicate whether it is necessary to take appropriate special measures to reduce the risks at the time of installation and/or use.

1.3.

Where the potential for misuse is known or can be clearly foreseen, the pressure equipment must be designed to prevent danger from such misuse or, if that is not possible, adequate warning given that the pressure equipment must not be used in that way.

2.

DESIGN

2.1.   General

The pressure equipment must be properly designed taking all relevant factors into account in order to ensure that the equipment will be safe throughout its intended life.

The design must incorporate appropriate safety coefficients using comprehensive methods which are known to incorporate adequate safety margins against all relevant failure modes in a consistent manner.

2.2.   Design for adequate strength

2.2.1.

The pressure equipment must be designed for loadings appropriate to its intended use and other reasonably foreseeable operating conditions. In particular, the following factors must be taken into account:

 internal/external pressure,

 ambient and operational temperatures,

 static pressure and mass of contents in operating and test conditions,

 traffic, wind, earthquake loading,

 reaction forces and moments which result from the supports, attachments, piping, etc.,

 corrosion and erosion, fatigue, etc.,

 decomposition of unstable fluids.

Various loadings which can occur at the same time must be considered, taking into account the probability of their simultaneous occurence.

2.2.2.

Design for adequate strength must be based on:

 as a general rule, a calculation method, as described in 2.2.3, and supplemented if necessary by an experimental design method as described in 2.2.4, or

 an experimental design method without calculation, as described in 2.2.4, when the product of the maximum allowable pressure PS and the volume V is less than 6 000 bar·L or the product PS·DN less than 3 000 bar.

2.2.3.

Calculation method

(a)   Pressure containment and other loading aspects

The allowable stresses for pressure equipment must be limited having regard to reasonably foreseeable failure modes under operating conditions. To this end, safety factors must be applied to eliminate fully any uncertainty arising out of manufacture, actual operational conditions, stresses, calculation models and the properties and behaviour of the material.

These calculation methods must provide sufficient safety margins consistent, where applicable, with the requirements of section 7.

The requirements set out above may be met by applying one of the following methods, as appropriate, if necessary as a supplement to or in combination with another method:

 design by formula,

 design by analysis,

 design by fracture mechanics;

(b)   Resistance

Appropriate design calculations must be used to establish the resistance of the pressure equipment concerned.

In particular:

 the calculation pressures must not be less than the maximum allowable pressures and take into account static head and dynamic fluid pressures and the decomposition of unstable fluids. Where a vessel is separated into individual pressure-containing chambers, the partition wall must be designed on the basis of the highest possible chamber pressure relative to the lowest pressure possible in the adjoining chamber,

 the calculation temperatures must allow for appropriate safety margins,

 the design must take appropriate account of all possible combinations of temperature and pressure which might arise under reasonably foreseeable operating conditions for the equipment,

 the maximum stresses and peak stress concentrations must be kept within safe limits,

 the calculation for pressure containment must utilize the values appropriate to the properties of the material, based on documented data, having regard to the provisions set out in section 4 together with appropriate safety factors. Material characteristics to be considered, where applicable, include:

 

 yield strength, 0,2 % or 1,0 % proof strength as appropriate at calculation temperature,

 tensile strength,

 time-dependent strength, i.e. creep strength,

 fatigue data,

 Young's modulus (modulus of elasticity),

 appropriate amount of plastic strain,

 impact strength,

 fracture toughness,

 appropriate joint factors must be applied to the material properties depending, for example, on the type of non-destructive testing, the materials joined and the operating conditions envisaged,

 the design must take appropriate account of all reasonably foreseeable degradation mechanisms (e.g. corrosion, creep, fatigue) commensurate with the intended use of the equipment. Attention must be drawn, in the instructions referred to in section 3.4, to particular features of the design which are relevant to the life of the equipment, for example:

 

 for creep: design hours of operation at specified temperatures,

 for fatigue: design number of cycles at specified stress levels,

 for corrosion: design corrosion allowance;

(c)   Stability aspects

Where the calculated thickness does not allow for adequate structural stability, the necessary measures must be taken to remedy the situation taking into account the risks from transport and handling.

2.2.4.

Experimental design method

The design of the equipment may be validated, in all or in part, by an appropriate test programme carried out on a sample representative of the equipment or the category of equipment.

The test programme must be clearly defined prior to testing and accepted by the notified body responsible for the design conformity assessment module, where it exists.

This programme must define test conditions and criteria for acceptance or refusal. The actual values of the essential dimensions and characteristics of the materials which constitute the equipment tested shall be measured before the test.

Where appropriate, during tests, it must be possible to observe the critical zones of the pressure equipment with adequate instrumentation capable of registering strains and stresses with sufficient precision.

The test programme must include:

(a) A pressure strength test, the purpose of which is to check that, at a pressure with a defined safety margin in relation to the maximum allowable pressure, the equipment does not exhibit significant leaks or deformation exceeding a determined threshold.

The test pressure must be determined on the basis of the differences between the values of the geometrical and material characteristics measures under test conditions and the values used for design purposes; it must take into account the differences between the test and design temperatures;

(b) where the risk of creep or fatigue exists, appropriate tests determined on the basis of the service conditions laid down for the equipment, for instance hold time at specified temperatures, number of cycles at specified stress-levels, etc.;

(c) where necessary, additional tests concerning other factors referred to in 2.2.1 such as corrosion, external damage, etc.

2.3.   Provisions to ensure safe handling and operation

The method of operation specified for pressure equipment must be such as to preclude any reasonably foreseeable risk in operation of the equipment. Particular attention must be paid, where appropriate, to:

 closures and openings,

 dangerous discharge of pressure relief blow-off,

 devices to prevent physical access whilst pressure or a vacuum exists,

 surface temperature taking into consideration the intended use,

 decomposition of unstable fluids.

In particular, pressure equipment fitted with an access door must be equipped with an automatic or manual device enabling the user easily to ascertain that the opening will not present any hazard. Furthermore, where the opening can be operated quickly, the pressure equipment must be fitted with a device to prevent it being opened whenever the pressure or temperature of the fluid presents a hazard.

2.4.   Means of examination

(a) Pressure equipment must be designed and constructed so that all necessary examinations to ensure safety can be carried out;

(b) Means of determining the internal condition of the equipment must be available, where it is necessary to ensure the continued safety of the equipment, such as access openings allowing physical access to the inside of the pressure equipment so that appropriate examinations can be carried out safely and ergonomically;

(c) Other means of ensuring the safe condition of the pressure equipment may be applied:

 where it is too small for physical internal access, or

 where opening the pressure equipment would adversely affect the inside, or

 where the substance contained has been shown not to be harmful to the material from which the pressure equipment is made and no other internal degradation mechanisms are reasonably foreseeable.

2.5.   Means of draining and venting

Adequate means must be provided for the draining and venting of pressure equipment where necessary:

 to avoid harmful effects such as water hammer, vacuum collapse, corrosion and uncontrolled chemical reactions. All stages of operation and testing, particularly pressure testing, must be considered,

 to permit cleaning, inspection and maintenance in a safe manner.

2.6.   Corrosion or other chemical attack

Where necessary, adequate allowance or protection against corrosion or other chemical attack must be provided, taking due account of the intended and reasonably foreseeable use.

2.7.   Wear

Where severe conditions of erosion or abrasion may arise, adequate measures must be taken to:

 minimize that effect by appropriate design, e.g. additional material thickness, or by the use of liners or cladding materials,

 permit replacement of parts which are most affected,

 draw attention, in the instructions referred to in 3.4, to measures necessary for continued safe use.

2.8.   Assemblies

Assemblies must be so designed that:

 the components to be assembled together are suitable and reliable for their duty,

 all the components are properly integrated and assembled in an appropriate manner.

2.9.   Provisions for filling and discharge

Where appropriate, the pressure equipment must be so designed and provided with accessories, or provision made for their fitting, as to ensure safe filling and discharge in particular with respect to hazards such as:

(a) on filling:

 overfilling or overpressurization having regard in particular to the filling ratio and to vapour pressure at the reference temperature,

 instability of the pressure equipment;

(b) on discharge: the uncontrolled release of the pressurized fluid;

(c) on filling or discharge: unsafe connection and disconnection.

2.10.   Protection against exceeding the allowable limits of pressure equipment

Where, under reasonably foreseeable conditions, the allowable limits could be exceeded, the pressure equipment must be fitted with, or provision made for the fitting of, suitable protective devices, unless the equipment is intended to be protected by other protective devices within an assembly.

The suitable device or combination of such devices must be determined on the basis of the particular characteristics of the equipment or assembly.

Suitable protective devices and combinations thereof comprise:

(a) safety accessories as defined in Article 1, section 2.1.3,

(b) where appropriate, adequate monitoring devices such as indicators and/or alarms which enable adequate action to be taken either automatically or manually to keep the pressure equipment within the allowable limits.

2.11.   Safety accessories

2.11.1.   Safety accessories must:

 be so designed and constructed as to be reliable and suitable for their intended duty and take into account the maintenance and testing requirements of the devices, where applicable,

 be independent of other functions, unless their safety function cannot be affected by such other functions,

 comply with appropriate design principles in order to obstain suitable and reliable protection. These principles include, in particular, fail-safe modes, redundancy, diversity and self-diagnosis.

2.11.2.   Pressure limiting devices

These devices must be so designed that the pressure will not permanently exceed the maximum allowable pressure PS; however a short duration pressure surge in keeping with the specifications laid down in 7.3 is allowable, where appropriate.

2.11.3.   Temperature monitoring devices

These devices must have an adequate response time on safety grounds, consistent with the measurement function.

2.12.   External fire

Where necessary, pressure equipment must be so designed and, where appropriate, fitted with suitable accesssories, or provision made for their fitting, to meet damage-limitation requirements in the event of external fire, having particular regard to its intended use.

3.

MANUFACTURING

3.1.   Manufacturing procedures

The manufacturer must ensure the competent execution of the provisions set out at the design stage by applying the appropriate techniques and relevant procedures, especially with a view to the aspects set out below.
