EN 804:1994

EN 804:1994 is a standard published by the European Committee for Standardization (CEN). Its full title is "Plastics piping systems - Injection-moulded socket fittings for solvent-cemented joints for pressure piping - Test method for resistance to a short-term internal hydrostatic pressure". This standard covers: This standard specifies a method for testing the resistance to internal hydrostatic pressure at 20 degrees C of infection-moulded thermoplastics fittings for connecting, by means of solvent cementing, to pressure pipes of the same type of material, having a nominal diameter, dn, less than or equal to 315 mm. 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 higher than the nominal pressure of the fitting.
