Scope
1.1 This specification establishes the performance characteristics required for Mechanically Attached Fittings (MAF). Mechanically Attached Fittings provide a fitting to pipe or tube connection, or both, by means other than welding, brazing, or threading. Successful completion of the tests described constitutes completion of the technical portion of the qualification process.
1.2 Supplementary requirements are provided for use when additional testing or inspection is desired. These shall apply only when specified in part or whole by the purchaser in the order. Unless otherwise specified, U.S. Navy contracts shall invoke the supplementary requirements in whole.
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.4 The following safety hazards caveat applies only to the tests listed in Section 13 and the tests described in the Supplementary Section and the Annex of this specification: This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
1.5 Unless specific MAF types are specified, the term "MAF" shall apply to all types described herein.
1.6 The tests specified in Section 13 and described in Annex
1.7 A fire performance test is specified in Supplementary Requirement S7. This test provides general guidelines to determine the responsiveness of MAF when subjected to fire. This test should not be considered for use to evaluate non-MAF products.
