ISO 13967 specifies a method of determining the ring stiffness of bends and branches made from thermoplastic material and for use with plastics pipes having a circular cross-section. The method can be used to determine the stiffness of bends, equal branches and unequal branches, provided the fitting allows a diametric deflection of at least 4 %.
Compression-testing machine, capable of a constant rate of crosshead movement appropriate to the nominal diameter of the fitting in accordance with table 1, with sufficient force and travel to produce the specified diametric deflection via a pair of bearing plates. By means of our testing expertise and modular product design, we will help find the solution that is right for you. Give our test engineers a call today for help configuring the best test machine and accessories according to ISO 13967.
