Описание
Значение и использование

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

4.2 Samples are taken for either of the following two purposes:

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

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

Область применения

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

1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

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.
