1/ Dimensions are in inches.
2/ Metric equivalents are given for information only.
3/ Hose assemblies vary in length among sizes. Category numbers shall be used to decide appropriate length
of hose for testing.
4.4.2 Qualification inspection routine. All samples shall be subjected to qualification testing in accordance
with table VI and in the sequence specified in table VII.
4.4.3 Acceptance of qualification data. For identical requirements and test procedures, using an identical
fitting or hose assembly, qualification test data from MIL-DTL-83296 and MIL-DTL-32330 may be accepted as
qualification test data for MIL-DTL-83298 providing that documented approval has been obtained from the
qualifying activity. Unless otherwise approved by the qualifying activity, qualification test data from one
manufacturer shall not be accepted for another.
4.4.4 Failures. One or more failures shall be cause for refusal to grant qualification approval.
