PLASTICS PIPING SYSTEMS - ELASTOMERIC SEALING RING TYPE JOINTS AND MECHANICAL JOINTS FOR THERMOPLASTICS PRESSURE PIPING - TEST METHOD FOR LEAKTIGHTNESS UNDER EXTERNAL HYDROSTATIC PRESSURE
This Malaysian Standard specifies a method for checking the leaktightness of elastomeric sealing ring type joints and mechanical joints (excluding fusion joints and adhesive type joints) for thermoplastics pressure piping when the external hydrostatic pressure is greater than the pressure within the pipe.
