General provisions

The supervision of manufacture shall be carried out by an Xa body and the tests as required in 6.2.6
shall be carried out either by that Xa body or by an IS-body approved by that Xa body; for definition
of Xa and IS bodies see definitions in 6.2.3.6.1. Conformity assessment shall be carried out by the
competent authority, its delegate or its approved inspection body of a Contracting Party to ADR.

By the application of 1.8.8, the applicant shall demonstrate, ensure and declare on his sole
responsibility the conformity of gas cartridges with the provisions of 6.2.6 and all further applicable
provisions of ADR.

The applicant shall
(a) Carry out a design type examination of each type of gas cartridges (including materials to be
used and variations of that type, e.g. volumes, pressures, drawings and closing and release
devices) according to 1.8.8.2;
(b) Operate an approved quality system for design, manufacture, inspection and testing according
to 1.8.8.3;
(c) Operate an approved testing regime according to 1.8.8.4 for the tests required in 6.2.6;
(d) Apply for the approval of his quality system for supervision of manufacture and for testing to
one Xa body of his choice of the Contracting Party; if the applicant is not established in a
Contracting Party he shall apply to one Xa body of a Contracting Party prior to first transport
into a Contracting Party;
(e) If the gas cartridge is finally assembled from parts manufactured by the applicant by one or
more other enterprise(s), provide written instructions how to assemble and fill the gas
cartridges to meet the provisions of his type examination certificate.

 

Where the applicant and enterprises assembling or filling gas cartridges according to the instructions
of the applicant, can demonstrate to the satisfaction of the Xa body conformity with the provisions of
1.8.7.6 excluding 1.8.7.6.1 (d) and 1.8.7.6.2 (b), they may establish an in-house inspection service
which may perform part or all of the inspections and tests specified in 6.2.6.

Design type examination

The applicant shall establish a technical documentation for each type of gas cartridges including the
technical standard(s) applied. If he chooses to apply a standard not referenced in 6.2.6, he shall add
the standard applied to the documentation.

The applicant shall retain the technical documentation together with samples of that type at the
disposal of the Xa body during production and afterwards for a period of minimum five years starting
from the last date of production of gas cartridges according to that type examination certificate.

The applicant shall after careful examination issue a design type certificate which shall be valid for a
maximum period of ten years; he shall add this certificate to the documentation. This certificate
authorises him to produce gas cartridges of that type for that period.

If within that period the relevant technical requirements of ADR (including referenced standards) have
changed so that the design type is no longer in conformity with them, the applicant shall withdraw his
type examination certificate and inform the Xa body.

The applicant may after careful and complete review reissue the certificate for another period of
maximum ten years.

Supervision of manufacture

The procedure of design type examination as well as the manufacturing process shall be subject to a
survey by the Xa body to ensure the type certified by the applicant and the product as produced are in
conformity with the provisions of the design type certificate and the applicable provisions of ADR. If
1.8.8.1.3 (e) applies, the assembling and filling enterprises shall be included in that procedure.

The applicant shall take all the necessary measures to ensure that the manufacturing process complies
with the applicable provisions of ADR and of his design type certificate and its annexes. If
1.8.8.1.3 (e) applies, the assembling and filling enterprises shall be included in that procedure.

The Xa body shall:
(a) Verify the conformity of the design type examination of the applicant and conformity of the
type of gas cartridges with the technical documentation specified in 1.8.8.2;
(b) Verify that the manufacturing process produces products in conformity with the requirements
and the documentation which apply to it; if the gas cartridge is finally assembled from parts
manufactured by the applicant by one or more enterprise(s), the Xa body shall also verify that
the gas cartridges are in full conformity with all applicable provisions after final assembly and
filling and that the instructions of the applicant are correctly applied;
(c) Verify that the personnel undertaking the permanent joining of parts and the tests are qualified
or approved;
(d) Record the results of its surveys.
