4.2 Inspection conditions. Unless otherwise specified, all inspections shall be performed in
accordance with the test conditions specified in 4.9.
4.3 Test equipment and inspection facilities. Test and measuring equipment and inspection
facilities of sufficient accuracy, quality, and quantity to permit performance of the required inspection
shall be established and maintained by the contractor. The establishment and maintenance of a
calibration system to control the accuracy of the measuring and test equipment (i.e. Industry Standard,
Military Standard) shall be in accordance with NCSL Z540 -1 or equivalent.
4.4 Responsibility for compliance. All items shall meet all requirements of sections 3, 4, and 5. The
inspection 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.
4.4.1 Assembly distributor. All manufacturing and/or assembling locations must be qualified for
listing on, or approved for listing on, the applicable qualified products list by the qualifying activity. This
includes manufacturing sites for the bulk hose and sites for assembling hose and fittings, regardless of
whether the site is operated by the original manufacturer or an authorized distributor producing hose
assemblies.
4.4.2 Manufacturers of hose assemblies. Manufacturers of hose assemblies shall qualify hose
assemblies assembled from parts obtained from specific qualified manufactures of fittings and hose. The
use of other qualified manufacturers fittings or hose shall require requalification of the hose assembly.
4.5 Qualification inspection. Qualification inspection shall be performed at a laboratory acceptable to
the qualifying activity on sample units produced with equipment and procedures used in production.
4.5.1 Samples for qualification. Qualification samples shall be representative of the products
proposed to be furnished to this specification. Samples consisting of 10 of each hose assembly size, with
lengths as specified in table I, shall be subjected to qualification testing. Each sample shall consist of a
hose, in accordance with MIL-DTL-8788, and fittings, in accordance with MIL-DTL-8789.
4.5.2 Qualification inspection routine. All hose assembly samples shall be subjected to qualification
4.5.3 Alternate qualification inspection criteria. Hose assemblies, consisting of hose and end fittings,
shall meet the requirements of 4.5.2. Alternatively, when the identical hose is manufactured and tested
in accordance with MIL-DTL-8788, and the identical hose fittings are manufactured and tested in
accordance with MIL-DTL-8789, and these items are later mated into a hose assembly in accordance
with MIL-DTL-8790, it is not necessary to test the hose assembly to meet the qualification requirements
of this specification. This applies when substantially identical test requirements and test procedures are
required for the assembly and the individual components and upon documented approval by the
qualifying activity.
