Die Annotation des Normtextes ASTM F3226/F3226M-19(2024) :

This specification establishes the material, manufacturing, performance, and testing requirements for Metallic Press-Connect Fittings used in piping and tubing systems with a maximum allowable working pressure of 300 psi. Metallic Press-Connect Fittings are directly attached 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. The seal may be created via the mechanical deformation (of the pipe, tube or fitting) or created independently. Press-Connect fittings shall be made from one or more of the following material grades: Grade A (carbon steel), Grade B (stainless steel), Grade C (copper and copper-alloy), Grade D (copper-nickel), and Grade E (brass). The fittings rated pressure shall be one of the following classes: Class 1 (100 psi [0.69 MPa] maximum), Class 2 (200 psi [1.38 MPa] maximum), and Class 3 (300 psi [2.07 MPa] maximum). The elastomeric seals are of three types: Type 1 (ethylene propylene diene monomer [EPDM]), Type 2 (hydrogenated nitrile butadiene rubber [HNBR], and Type 3 (fluoro-elastomer or synthetic fluorinated rubber [FKM]).
