This standard is a general tensile creep test (hereinafter referred to as creep test) method for carbon fiber reinforced plastics (hereinafter referred to as CFRP), in which a test piece is subjected to a constant tensile load (hereinafter referred to as , referred to as the test load), to measure the tensile creep elongation of the test piece and/or to measure the time from the start of the test until the test piece reaches failure or a specified tensile creep strain. . However, this method is not applicable to tests that measure the tensile creep elongation of unidirectional CFRP, which is performed by aligning the loading direction with the fiber axis.
