ISO 13967:2009规定了一种测定热塑性材料弯管和支管环刚度的方法,该弯管和支管用于具有圆形横截面的塑料管。该方法可用于确定弯管、等支管和不等支管的刚度,前提是配件允许至少4%的径向挠度。
ISO 13967:2009 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 %.
