This International Standard specifies a method for the determination of the time-to-failure of thermoplastics resins and compounds for piping and fitting applications by the use of a plane strain grooved tensile specimen in a stress-rupture test.<\/p>\n
The grooved tensile specimen produces a biaxial state of stress on uni-axial loading, which is taken to be indicative of the stress conditions found in pressurized solid-wall plastics pipes. The ratio of the stress in the axial direction to the transverse direction approximates that for a pressurized end-capped solid-wall pipe specimen[4]\u2013[7]<\/sup>.<\/p>\n It is intended that the data generated on these specimens be utilized to determine the stress-rupture (time to failure) resistance of moulding materials for pipes and fittings as well as experimental piping resins.<\/p>\n This method is also applicable to stress-rupture evaluations of pipes which are difficult to test, e.g. larger diameter pipes, including their batch release tests.<\/p>\n This International Standard is not intended to replace the stress-rupture test of ISO 1167[2]<\/sup>, which uses internally pressurized end-capped pipes.<\/p>\n Determination of specimen dimensions for the plane strain condition <\/td>\n<\/tr>\n Thermoplastics pipes for the conveyance of fluids.
