ASTM F1122-04 (R2021) pdf free download.Standard Specification for Quick Disconnect Couplings (6 in. NPS and Smaller).
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) that fits into a female coupling half (coupler) of the same size. By closing attached cam handles, the coupling halves seal, permitting fluids to he transported under pressure through the quick disconnect coupling.
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 arc provided for information only and arc not considered standard.
6.1.3 All material incorporated in the work covered by this specification shall be new. The use of rebuilt or used products are not allowed under this specification.
6.1.4 Gaskets are to be produced from a compressible elastomeric material and shall he compatible with the fluid to he transferred (see 5.1.4).
6.2 Manuficiure:
6.2.1 Adapters and couplers are to he produced as castings or forgings. Cam handles may he produced by casting. forging, or sintered metal processes. Established commercial processing methods are to be used to produce these parts. provided chemical and physical properties are consistent with those cataloged for the specified materials.
6.2.2 Pipe threads on the service end of couplers or adapters. when specified, shall meet ASME/ANSI B2.1.
6.2.3 Flanges on the service end of couplers or adapters. when specified. shall meet ASME B 16.5, B 16.24, or B 16.42.
6.2.4 Flanges shall be finish machined to specifications shown in MSS-SP-6.
6.2.5 Cam handles assembled to the coupler are to have a safety locking device to ensure against the handles being
opened unintentionally or vibrating open. This locking device must require a separate. deliberate effort in the opening operation over the standard handle operation.
6.2.6 Cam handles shall be manufactured to contain the adapter within the coupler under rated pressure with no leakage occurring. The cam action shall not distort the couplers rendering the coupler unusable. The force required to close the cam handles shall be adequate to prevent leakage, but shall be easily attainable through hand operation by an average strength person. Handles should not need to be hammered closed.ASTM F1122 pdf download.
