4.4.3.2.2 Hose assemblies. Hose assemblies if one or more defects are identified, then the entire
production lot shall be screened for that defect and all defects shall be either removed or reworked. A
second inspection sample shall then be selected from the different lot and the sampling tests shall be
performed again. If one or more defects are identified from the second inspection lot then the lot shall be
considered as failed.
4.4.4 Sampling for destructive testing. One hose length shall be randomly selected from each lot and
submitted for inspection. After examining the length of hose in accordance with 4.6.1, the hose shall be
cut approximately 3 feet (914.4 mm) from one end and 15 inches (381 mm) from the other end. These
will provide lengths for the pull test (see 4.6.5) and the burst pressure test (see 4.6.8). Additional lengths
of hose shall be cut from the original length for the remaining tests required. When hose is ordered in
short lengths and is insufficient for tests, the manufacturer shall furnish extra lengths for test purposes.
Samples subjected to destructive testing shall not be supplied as part of the contract or order.
4.4.5 Disposition of first article samples. Unless otherwise specified, after award of the contract or
order, the manufacturer shall forward (1 hose or hose assembly), fabricated from random samples of the
hose or hose assembly. The sample shall be representative of the construction, workmanship,
components, and materials to be used during production. When a manufacturer is in continuous
production of the hose and hose assemblies from one contract to another, submission of additional first
article samples for a new contract may be waived at the discretion of the acquiring activity (see 6.2).

requirements shall be coordinated through the preparing activity; DLA Land and Maritime, Columbus,
