QUALITY ASSURANCE PROVISIONS
4.1 Responsibility for inspection. Unless otherwise specified in the
contract or purchase order, the contractor is responsible for the performance of
all inspection requirements (examinations and tests) as specified herein. Except
as otherwise specified in the contract or purchase order, the contractor may use
his own or any other facilities suitable for the performance of the inspection
requirements specified herein, unless disapproved by the Government. The
Government reserves the right to perform any of the inspections set forth in the
specification, where such inspections are deemed necessary to ensure supplies and
services conform to prescribed requirements.
4.1.1 Responsibility for compliance. All items shall meet all requirements
of Sections 3 and 5. The inspections set forth in this specification shall
become a part of the contractor's overall inspection system or quality program.
The absence of any inspection requirements in the specification shall not relieve
the contractor of the responsibility of ensuring that all products or supplies
submitted to the Government for acceptance comply with all requirements of the
contract. Sampling inspection, as part of manufacturing operations, is an
acceptable practice to ascertain conformance to requirements, however this does
not authorize submission of known defective material, either indicated or actual,
nor does it commit the Government to accept defective material.
4.2 Classification of inspections.
The inspection requirements specified
herein are classified as follows:
Qualification inspection (see 4.3).
First article inspection ( see 4.4).
Quality conformance inspection (see 4.5).
Quality conformance verification inspection (see 4.6).
4.3 Qualification inspection. Qualification inspection shall be as
specified in Table VII, in the order specified.
4.3.1 Qualification samples. Qualification samples shall consist of four
complete regulators, three elastomer slabs, and two sets of the manufacturer's
drawings for the samples submitted (see 6.4). The elastomer slabs shall be 6 by
6 by 0.075 inch and composed of the identical ozone resistant composition and
cure that was used in manufacturing the elastometer components. Samples shall be
forwarded to a test facility set forth in the letter of authorization to submit
samples (see 6.4). The samples shall be plainly identified by securely attached
durable tags marked with the following information:
