PLASTICS PIPING SYSTEMS - INJECTION-MOULDED THERMOPLASTICS FITTINGS FOR ELASTIC SEALING RING TYPE JOINTS FOR PRESSURE PIPING - TEST METHOD FOR RESISTANCE TO A SHORT-TERM INTERNAL PRESSURE WITHOUT END THRUST
This Malaysian Standard specifies a method for testing the resistance to internal hydrostatic pressure at 20°C of any injection-moulded thermoplastics fittings with elastic sealing ring type joints for thermoplastics pressure pipes having a nominal diameter, dn, less than or equal to 315 mm, where the joint is not intended to withstand hydrostatic end thrust.
This method is intended for testing fittings over a period of the order of 1 h to 10 h at a pressure which is material-dependent and typically several times the nominal pressure of the fitting.
