36、e the same physical characteristics (dimensions, materials, manufacturing methods, heat treatment, surface finish, etc.), being manufactured under the same conditions and submitted together for inspection. 9.3 Materials Materials shall conform to the specifications as specified or described in detai
37、l in the product standard. Other materials not specified or described in the product standard, may be introduced by the manufacturer to ensure compliance with technical requirements. BS EN 6138:2017EN 6138:2017 (E) 9 The suitability of materials not specified in the product standard shall be verifie
38、d by qualification tests. Any changes to materials shall be approved by the customer prior to the next delivery. 9.4 Approval of manufacturers The manufacturers quality system shall conform to EN 9100 or equivalent. The purpose of these procedures is to ensure that a manufacturer has a quality syste
39、m and the capability for continuous manufacture and release of parts complying with the specified quality requirements. The granting of an approval of the manufacturer is a function of the Certification Authorities, or their appointed representative, who is a prime contractor. 9.5 Responsibility for
40、 inspection Unless otherwise specified in the contract or purchase order, the supplier is responsible for the completion of all inspection requirements as specified in this specification. The supplier may use his own or other approved facilities and inspection methods to achieve satisfactorily the i
41、nspection requirements as covered by this specification. The customer reserves the right to perform counter-acceptance tests to ensure performance attains the required characteristics. 9.6 Labelling All packages shall be permanently and legibly marked with the following: the full standard part desig
42、nation; manufacturers name and address; order or purchase number. 9.7 Unit and transport packages The products shall be packed in unit or transport packages that comply with the customers requirements.
