This standard specifies the force changes and transformations that occur when compression coil springs and tension coil springs (hereinafter referred to as coil springs) made of shape memory alloys are fixed at a constant strain and are subjected to temperature changes (cooling and heating) at a constant rate. Specify the test method for measuring the points.
