Thermoplastics fittings. Determination of ring stiffness Ingestion-build-156411 Minimum yield strengths up to1 Scope This International Standard 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 %. NOTE 1 If a fitting has the same wall thickness, wall construction, material and
