ASTM D4024-22

Anotace textu normy ASTM D4024-22 :

This specification deals with the testing and performance requirements of machine made ""fiberglass"" (glass-fiber-reinforced thermosetting resin) flanges, other than those that are contact-molded. Flanges may be produced integrally with a pipe or fitting, may be produced with a socket for adhesive bonding to a pipe or fitting, or may be of the type used in conjunction with either a metallic or nonmetallic backup ring. Flanges are defined by type (method of manufacture), grade (generic type of resin), class (configuration of joining system), and pressure rating. Flanges are also given numerical classifications relating to rupture pressure, sealing test pressure, and bolt torque limit. Included are requirements for materials, workmanship, performance, and dimensions.
