Compressive Properties-ASTM D695

压缩性能（ASTM D 695 and ISO 604） Compressive Properties-ASTM D695, ISO 604 Specimen Size: Specimens can either be blocks or cylinders. For ASTM, the typical blocks are 12.7 x 12.7 x 25.4mm (½ by ½ by 1 in). and the cylinders are 12.7mm (½ in) in diameter and 25.4mm (1 in) long. For ISO, the preferred specimens are 50 x 10 x 4mm for modulus and 10 x 10 x 4mm for strength.
