This International Standard specifies methods for high speed compression testing, at room temperature, of porous and cellular metals having a porosity of 50 % or more. The speed range applicable to this test method is 0,1 m/s to 100 m/s (or 1 s^(−1) to 10^(3) s^(−1) in terms of the initial strain rate when the specimen height is 100 mm).
