适用范围：This European Standard specifies a method for determining the dry creep factor of glass-reinforced plastics pipes. It is applicable to pipes with an initial specific ring stiffness of not less than 630 N/m, when determined by the method specified in the referring standard. NOTE. For this purpose plates or beam bars are considered to be equally valid for loading the test piece up to a relative deflection of 28 %. When it is expected that the relative deflection will be more than 28 %, then the test is to be conducted using beam bars (see 8.3).
