This standard specifies certain methods for general creep testing (hereinafter referred to as creep testing) of carbon fiber reinforced plastics (hereinafter referred to as CFRP) using the 3-point bending method (method A) and the 4-point bending method (method B). Under the test atmosphere, a constant bending load (hereinafter referred to as test load) is applied to the test piece for a long period of time, and the bending creep deflection of the test piece is measured and/or the test piece breaks or reaches a certain specified bending level from the start of the test. Specifies the method for measuring the time until creep strain is reached.
