Arashikazahn The specimens shall be taken from locations distributed throughout the sample. Thus, the value of Wa is zero in the above calculation when the sample is at equilibrium with the air. There are no recognized standards on which to base an estimate of bias for this test method. When a sliding caliper gage is used, the proper setting shall be that point at which the measuring faces of the gage contact the surfaces of the specimen without compressing them.

A lesser number may be made when the following conditions apply: Any test specimen preparation, conditioning, dimensions, or testing parameters, or combination thereof, covered in the relevant ASTM materials specification shall take precedence over those mentioned in this test method. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. The principles of Revised D value for Material 3 in Table 1.

Density can be evaluated as the apparent overall density includes forming skins or by apparent core density forming skins removed.
