ASTM D2924 STANDARD FOR EXTERNAL PRESSURE RESISTANCE OF FIBERGLASS PIPE
This test method developed by ASTMcovers determination of the resistance of fiberglass pipe to external pressure. It classifies failures as buckling, compressive, and leaking. Both glass-fiber-reinforced thermosetting-resin pipe (RTRP) and glass-fiber-reinforced polymer mortar pipe (RPMP) are fiberglass pipes.
