ASTM D 695 and ISO 604Compressive Properties-ASTM D695, ISO 604Specimen Size:Specimens can either be blocks or cylinders. For ASTM, the typical blocks are 12.7 x 12.7 x 25.4mm ( by by 1 in). and the cylinders are 12.7mm ( 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.ISO 527-1,-2Tensile Properties - ISO 527-1,-2Test Specimen Summary
