Conformity assessment system and approval for manufacture of pressure receptacles

6.2.2.5.1

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;

standard;

Verify means confirm by examination or provision of objective evidence that specified requirements

have been fulfilled.

6.2.2.5.2

General requirements

Competent authority

6.2.2.5.2.1

The competent authority that approves the pressure receptacle shall approve the conformity

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.

6.2.2.5.2.2

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

in part.

6.2.2.5.3.1

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;

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;
