Anotace textu normy ASTM F1387-23 :
This specification establishes the performance characteristics required for mechanically attached fittings (MAFs) for use in piping and tubing systems. These fittings directly attach to pipe or tube by mechanical deformation of the pipe or tube or fitting, or a combination thereof, creating a seal and a restrained joint. process. MAFs covered here are classified into the following design types: Type I—radially swaged MAF (permanent); Type II—flared MAF (separable); Type III—flareless (bite-type) MAF (separable); Type IV—grip-type MAF (separable); Type V—shape memory alloy (SMA) MAF (permanent); and Type VI—axially swaged MAF (permanent). Moreover, the MAFs shall be made from on or more of the following material grade: Grade A—carbon steel; Grade B—stainless steel; Grade C—nickel-copper; Grade D—copper-nickel; Grade E—brass; and Grade F—nickel titanium. The MAFs shall also be grouped into ten classes according to their pressure ratings. The standard qualification tests to which the MAFs shall perform satisfactorily are pneumatic proof test, hydrostatic proof test, impulse test, flexure fatigue test, tensile test, hydrostatic burst test, repeated assembly test, rotary flexure test, and mercurous nitrate test. Successful completion of the tests described constitutes completion of the technical portion of the qualification
