This practice provides procedures astm c702 reducing the large sample obtained in the field, or produced in the laboratory, ast, a convenient size for conducting a number of descriptive and quality tests.

ASTM C Standard

Other factors being equal, larger samples will tend to be more representative of the total astm c702. Chance inclusion or exclusion of only one or two particles in the selected test sample may importantly influence interpretation of the astm c702 of the original sample.

Historical Version s – view previous versions of standard. Link to Active This link will always route to the aastm Active version of the standard. In these cases, the entire original sample should be tested. Failure to carefully follow the procedures in this practice could result in astm c702 a non-representative sample to astm c702 used in subsequent testing.


ASTM C / CM – 18 Standard Practice for Reducing Samples of Aggregate to Testing Size

It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Substantial differences astm c702 the selected test samples sometimes cannot be avoided, for example, in the astm c702 of an aggregate having relatively few large size particles in the astm c702. These techniques are intended to minimize variations in measured characteristics between the test samples selected and the large sample.

The laws of chance dictate that these few asym astm c702 be unequally distributed among the reduced size test samples. The alternative astm c702 given in parentheses is for information only and does not represent a different standard sieve size.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.


The individual test methods provide for minimum amount of material to be tested. Sieve size is identified by its standard designation in Specification E Work Item s – proposed revisions of this standard. Combining values from the two systems may result in non-conformance with the standard. Similarly, if the test sample is being examined for certain contaminants occurring in astm c702 small percentages, caution should be used in astm c702 results from the reduced astm c702 test sample.
