Conformity assessment system and approval for manufacture of pressure receptacles

Definitions

For the purposes of this sub-section:
Conformity assessment system means a system for competent authority approval of a manufacturer, by
pressure receptacle design type approval, approval of manufacturer's quality system and approval of
inspection bodies;
Design type means a pressure receptacle design as specified by a particular pressure receptacle
standard;
Verify means confirm by examination or provision of objective evidence that specified requirements
have been fulfilled.

General requirements

Competent authority

The competent authority that approves the pressure receptacle shall approve the conformity
assessment system for the purpose of ensuring that pressure receptacles conform to the requirements
of ADR. In instances where the competent authority that approves a pressure receptacle is not the
competent authority in the country of manufacture, the marks of the approval country and the country
of manufacture shall be indicated in the pressure receptacle marks (see 6.2.2.7 and 6.2.2.8).
The competent authority of the country of approval shall supply, upon request, evidence
demonstrating compliance to this conformity assessment system to its counterpart in a country of use.

The competent authority may delegate its functions in this conformity assessment system in whole or
in part.

The competent authority shall ensure that a current list of approved inspection bodies and their
identity marks and approved manufacturers and their identity marks is available.

Inspection body

The inspection body shall be approved by the competent authority for the inspection of pressure
receptacles and shall:
(a) Have a staff with an organizational structure, capable, trained, competent, and skilled, to
satisfactorily perform its technical functions;
(b) Have access to suitable and adequate facilities and equipment;
(c) Operate in an impartial manner and be free from any influence which could prevent it from
doing so;
(d) Ensure commercial confidentiality of the commercial and proprietary activities of the
manufacturer and other bodies;
(e) Maintain clear demarcation between actual inspection body functions and unrelated
functions;
(f) Operate a documented quality system;
(g) Ensure that the tests and inspections specified in the relevant pressure receptacle standard and
ADR are performed; and
(h) Maintain an effective and appropriate report and record system in accordance with 6.2.2.5.6.

The inspection body shall perform design type approval, pressure receptacle production testing and
inspection, and certification to verify conformity with the relevant pressure receptacle standard
(see 6.2.2.5.4 and 6.2.2.5.5).

Manufacturer

 
The manufacturer shall:
(a)         Operate a documented quality system in accordance with 6.2.2.5.3;
 
(b)         Apply for design type approvals in accordance with 6.2.2.5.4;
 
(c)  Select an inspection body from the list of approved inspection bodies maintained by the   
competent authority in the country of approval; and
 
(d)         Maintain records in accordance with 6.2.2.5.6.
 

Testing laboratory

 
The testing laboratory shall have:
(a)         Staff with an organizational structure, sufficient in number, competence, and skill; 
and
 
(b) Suitable and adequate facilities and equipment to perform  the  tests  required  by  the 
manufacturing standard to the satisfaction of the inspection body.
 

Manufacturer's quality system

The quality system shall contain all the elements, requirements, and provisions adopted by the
manufacturer. It shall be documented in a systematic and orderly manner in the form of written
policies, procedures and instructions.
The contents shall in particular include adequate descriptions of:
(a) The organizational structure and responsibilities of personnel with regard to design and
product quality;
(b) The design control and design verification techniques, processes, and procedures that will be
used when designing the pressure receptacles;
(c) The relevant pressure receptacle manufacturing, quality control, quality assurance and
process operation instructions that will be used;
(d) Quality records, such as inspection reports, test data and calibration data;
(e) Management reviews to ensure the effective operation of the quality system arising from the
audits in accordance with 6.2.2.5.3.2;
(f) The process describing how customer requirements are met;
(g) The process for control of documents and their revision;
(h) The means for control of non-conforming pressure receptacles, purchased components, inprocess
and final materials; and
(i) Training programmes and qualification procedures for relevant personnel.
