ASTM D3665−12 Standard Practice for Random Sampling of Construction Materials

Scope
1.1 This practice covers the determination of random locations (or timing) at which samples of construction materials can be taken.

For the exact physical procedures for securing the sample, such as a description of the sampling tool, the number of increments needed for a sample, or the size of the sample, reference should be made to the appropriate standard method.

The selection procedures in Section 6 utilize the table of four-digit numbers given in Table 1.

1.2 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.
