ASTM D140-01(2007)

Sampling is as important as testing, and precautions shall be taken to obtain samples to show the true nature and condition of the materials.

Samples are taken for either of the following two purposes:

3.2.1 To represent as nearly as possible an average of the bulk of the materials sampled, or

3.2.2 To ascertain the maximum variation in characteristics which the material possesses.

1.1 This practice applies to the sampling of bituminous materials at points of manufacture, storage, or delivery.

1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
