the Annual Book of ASTM Standards. 4. Significance and Use 4.1 The volume of an arbitrary P/M shape cannot be accurately measured by standard techniques such as by mi-crometers or calipers. Since density is mass/volume, a precise method to measure the volume is needed. For nonporous objects, the volume of water displaced by the immersed object
