ASTM F1122-22

Standard Specification for Quick Disconnect Couplings (6 in. NPS and Smaller)

ABSTRACT
This specification covers the manufacturing data required to produce a variety of styles and sizes of quick disconnect couplings up to and including NPS 6 for marine use that ensure interchangeability and safety of operation. Quick disconnect couplings shall consist of the following types: Standard class and Class I. Adapters and couplers are to be produced as castings or forgings. Cam handles may be produced by casting, forging, or sintered metal processes. Maximum allowable working pressure (MAWP) for a Standard Class coupling shall be 25 % of its burst pressure. Maximum allowable working pressure for a Class I coupling shall be 20 % of its burst pressure. The following test shall be performed: pressure tests and production test.
SCOPE
1.1 This specification covers the manufacturing data required to produce a variety of styles and sizes of quick disconnect couplings up to and including NPS 6 for marine use that ensure interchangeability and safety of operation.  
1.2 In general, quick disconnect couplings are hose and pipe end fittings that permit quick mechanical attachment by means other than bolted or threaded fittings. The method of attachment is a male coupling half (adapter, tank unit) that fits into a female coupling half (coupler, hose unit) of the same size.  
1.2.1 By closing attached cam handles on cam and groove couplings, the coupling halves seal, permitting fluids to be transported under pressure through the quick disconnect coupling.  
1.2.2 By aligning the rollers on the hose unit coupler with the notches on the tank unit adapter on the dry disconnect coupling (DDC), push the coupler onto the adapter and rotate past 100°. This will lock the couplings together, create a seal and open the internal valves for full flow with low pressure drop. The dual poppet design shut-off mechanism seals liquids and gases behind the valve, eliminating fugitive emissions and the danger of a spill upon disconnection.  
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.4 The following safety hazards caveat pertains only to the test method described in this specification:  This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
