4.4.3 Acceptance of hose assembly qualification inspection data. Required qualification tests at the
hose assembly level that were already performed at the bulk hose level may be waived if documented
approval has been obtained from the qualifying activity.
4.4.4 Alternate qualification inspection criteria. Hose shall meet the requirements of 4.4.2.
Alternatively, when the identical fittings are manufactured and tested in accordance with MIL-DTL-8789,
and identical hose assemblies are manufactured and tested in accordance with MIL-DTL-8790, using
identical hose in accordance with MIL-DTL-8788, it is not necessary to test the hose to meet the

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.
4.4.5 Failures. One or more failures shall be cause for refusal to grant qualification approval.
4.4.6 Summary of test. If the summary of test results indicates nonconformance with the
