Astm c702 inclusion or exclusion of only one or two particles in the selected test sample may importantly influence interpretation of the characteristics of the original sample. Sieve size is identified by its standard designation in Specification E Similarly, if the test sample is being examined for certain contaminants occurring in only small percentages, caution astm c702 be used in interpreting results from the reduced size test sample.

In these cases, the entire original sample should astm c702 tested.

The individual test methods provide for minimum astm c702 of material to be tested. The values stated in each system may not be exact equivalents; c02, each system shall be used independently of the other.

ASTM C – 98 Standard Practice for Reducing Samples of Aggregate to Testing Size

Substantial differences astm c702 the selected astm c702 samples sometimes cannot be avoided, for example, in the case of an aggregate having relatively few large size particles in the sample. Work Item s – proposed revisions of this standard.

This practice provides procedures for reducing the large sample obtained in the field, or produced in the laboratory, to a convenient size for conducting a number of descriptive and quality tests. Combining values from the two systems may result in non-conformance with the standard. The alternative astm c702 given in parentheses is for information only and does not represent a different standard sieve astm c702.

Failure to carefully follow the procedures in this practice could result in providing a non-representative sample to be used in subsequent testing. Astm c702 factors being astm c702, larger samples will tend to be more representative of the total supply. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the c70 of regulatory limitations prior to use.

These techniques are intended to minimize variations in measured characteristics between the test samples selected and the large sample.

The laws of chance astm c702 that these few particles may be unequally distributed among the reduced size test samples.
