Voorstel voor een BESLUIT VAN DE RAAD betreffende de aanvaarding door de Europese Gemeenschap van Reglement nr. 106 van de Economische Commissie voor Europa van de Verenigde Naties inzake de goedkeuring van luchtbanden voor landbouwvoertuigen en aanhangwagens daarvan

(door de Commissie ingediend)

TOELICHTING

1. Algemeen

Uit hoofde van Besluit 97/836/EG van de Raad van 27 november 1997 is de EG op 24 maart 1998 toegetreden tot de Herziene overeenkomst van 1958 van de Europese Commissie voor Europa van de Verenigde Naties (VN/ECE) en heeft zij 78 bij deze Overeenkomst gevoegde reglementen aanvaard.

In artikel 3, lid 3, van dit besluit is bepaald dat de Gemeenschap kan besluiten een reglement dat zij bij de toetreding tot de Herziene overeenkomst niet heeft aanvaard, alsnog te zullen toepassen wanneer de Raad, met instemming van het Europees Parlement, dit reglement bij gekwalificeerde meerderheid goedkeurt.

Reglement nr. 106 inzake de goedkeuring van luchtbanden voor landbouwvoertuigen en aanhangwagens daarvan moet de technische handelsbelemmeringen voor landbouwvoertuigen tussen de overeenkomstsluitende partijen uit de weg ruimen waarbij een hoog niveau van veiligheid en milieubescherming wordt gewaarborgd. Ofschoon dit reglement niet in de in bijlage II bij Besluit 97/836/EG opgenomen lijst van door de EG aanvaarde reglementen voorkomt, hebben de vertegenwoordigers van de lidstaten laten weten dat het nuttig zou zijn als de EG de mogelijkheid van aanvaarding ervan zou onderzoeken. Voorts is het de bedoeling dat dit reglement zal worden geïntegreerd in het communautaire typegoedkeuringsstelsel voor land- en bosbouwtrekkers, zulks ter aanvulling van de geldende wetgeving van de Gemeenschap.

Er zij op gewezen dat de EG haar besluit over de aanvaarding van dit reglement zal nemen op basis van het in de officiële talen van de VN/ECE (Frans, Engels en Russisch) beschikbare document. De tekst van Reglement nr. 106 is derhalve uitsluitend in de Franse en de Engelse versie bijgevoegd.

Overeenkomstig het bepaalde in artikel 4, lid 5, van Besluit 97/836/EG zal Reglement nr. 106 niettemin nog vóór de inwerkingtreding ervan voor de Gemeenschap in alle officiële talen van de Gemeenschap in het Publicatieblad worden bekendgemaakt.

2. Inhoud van het voorstel

Het voorgestelde besluit moet de Gemeenschap in staat stellen Reglement nr. 106 van de VN/ECE inzake de goedkeuring van luchtbanden voor landbouwvoertuigen en aanhangwagens daarvan te aanvaarden.

D = d + 2 H

where:

D is the outer diameter expressed in mm,

d is the conventional number denoting the nominal rim diameter expressed in mm (see paragraph 2.16.),

H is the nominal section height in mm and is equal to:

H = 0.01 x Ra x S1

where:

Ra is the nominal aspect ratio,

S1 is the "nominal section width" in mm all as shown on the sidewall of the tyre in the tyre-size designation in conformity with the requirements of paragraph 2.15.

6.5. Test procedures

6.5.1. The actual dimensions of tyres are measured as prescribed in annex 6.

6.5.2. The test procedure to assess the resistance of the tyre to burst is described in annex 8.

6.5.2.1. A tyre which, after undergoing the relevant test to assess the resistance to burst, does not exhibit any tread separation, ply separation, cord separation, broken beads or broken cords is deemed to have passed the test. The tyre tested shall not be used for any other tests.

6.5.3. The test procedures to assess the suitability of the tyre for the claimed performances are described in annex 9.

6.5.3.1. A tyre which, after undergoing the relevant load/speed test, does not exhibit any tread separation, ply separation, cord separation or broken cords is deemed to have passed the test. The tyre tested shall not be used for any other tests.

6.5.3.2. A tyre which, after undergoing the relevant load/speed test, does exhibit chunking, due to the specific test conditions is deemed to have passed the test.

6.5.4. Where a tyre manufacturer produces a range of tyres it is not considered necessary to carry out tests on every type of tyre in the range.

7. MODIFICATION OF TYRE TYPE AND EXTENSION OF APPROVAL

7.1. Every modification of a tyre type shall be notified to the administrative department which approved the tyre type. That department may then either:

7.1.1. Consider that the modifications made are unlikely to have an appreciable adverse effect and that in any case the tyre still meet the requirements; or

7.1.2. Require a further test report from the technical service responsible for carrying out the tests.

7.2. A modification of the tread pattern of the tyre shall not be considered to necessitate a repetition of the tests prescribed in paragraph 6 of this Regulation.

7.3. Confirmation or refusal of approval, specifying the alterations, shall be communicated by the procedure specified in paragraph 5.3. above to the Parties to the Agreement which apply this Regulation.

7.4. The competent authority issuing the extension of approval shall assign a series number for such an extension and inform thereof the other Parties to the 1958 Agreement applying this Regulation by means of a communication form conforming to the model in annex 1 to this Regulation.

8. CONFORMITY OF PRODUCTION

The conformity of production procedures shall comply with those set out in the Agreement, Appendix 2 (E/ECE/324-E/ECE/TRANS/505/Rev.2), with the following requirements:
