The components shown shall be type approved pursuant to the provisions laid down in the Annexes which can be determined from the table below:.

Every modification of a type of CNG component shall be notified to the administrative department which granted the type-approval. The department may then either:. Consider that the modifications made are unlikely to have an appreciable adverse effect, and that the component still complies with the requirements; or. Determine whether partial or complete retesting has to be established by the competent authority.

Confirmation or refusal of approval, specifying the alterations, shall be communicated by the procedure specified in paragraph 5. The competent authority issuing the extension of approval shall assign a series number to each communication form drawn up for such an extension. Every container shall be tested at a minimum pressure of 1,5 times the working pressure in conformity with the prescriptions of Annex 3 of this Regulation.

Burst testing under hydraulic pressure according to paragraph 3. Every flexible fuel line assembly which is applied in the high and medium pressure Class 0, 1 according to the classification as described in paragraph 2 of this Regulation shall be tested at the pressure twice the working pressure. The approval granted in respect of a type of component pursuant to this Regulation may be withdrawn if the requirements laid down in paragraph 9 above are not complied with.

If a Party to the Agreement applying this Regulation withdraws an approval it has previously granted, it shall forthwith so notify the other Contracting Parties applying this Regulation, by means of a communication form conforming to the model in Annex 2B to this Regulation.

If the holder of the approval completely ceases to manufacture a type of component approved in accordance with this Regulation, he shall so inform the authority which granted the approval. Upon receiving the relevant communication, that authority shall inform thereof the other Parties to the Agreement applying this Regulation by means of a communication form conforming to the model in Annex 2B to this Regulation.

The Parties to the Agreement applying this Regulation shall communicate to the United Nations Secretariat the names and addresses of the technical services responsible for conducting approval tests and of the administrative departments which grant approval and to which forms certifying approval or extension or refusal or withdrawal of approval, issued in other countries, are to be sent. The application for approval of a vehicle type with regard to the installation of specific components for the use of compressed natural gas in its propulsion system shall be submitted by the vehicle manufacturer or by his duly accredited representative.

It shall be accompanied by the under-mentioned documents in triplicate: description of the vehicle comprising all the relevant particulars referred to in Annex 1B to this Regulation. A vehicle representative of the vehicle type to be approved shall be submitted to the technical service conducting the approval tests. If the vehicle submitted for approval pursuant to this Regulation is provided with all the necessary specific components for the use of compressed natural gases in its propulsion system and meets the requirements of paragraph 17 below, approval of that vehicle type shall be granted.

An approval number shall be assigned to each type of vehicle approved. Its first two digits shall indicate the series of amendments incorporating the most recent major technical amendments made to the Regulation at the time of issue of the approval. Notice of approval or of refusal or of extension of approval of a CNG vehicle type pursuant to this Regulation shall be communicated to the Parties to the Agreement applying this Regulation, by means of a form conforming to the model in Annex 2D to this Regulation.
