Failure to carefully follow the procedures in this practice could result asttm providing a non-representative sample to be used in subsequent testing. Astm c702 to Active This link will always route to the astm c702 Active version of the standard.
ASTM C – 98 Standard Practice for Reducing Samples of Aggregate to Testing Size
These techniques are intended to minimize variations in measured characteristics between the test samples selected and the large sample. Similarly, if the test sample is being examined for certain contaminants occurring in only small percentages, caution should be used in interpreting results from the reduced size test sample.
The laws of chance dictate that these few particles may be unequally distributed among the reduced size test samples. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Chance inclusion or exclusion asym only one or two particles in the selected test sample may importantly influence interpretation astm c702 the characteristics of the original sample. In astm c702 cases, the entire original sample should be tested.

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. It is the responsibility of the user of this standard astm c702 establish appropriate safety, health, and environmental practices and determine the applicability c7702 regulatory limitations prior to use.

Combining values from the two systems may result in non-conformance with the standard. Substantial differences astm c702 the selected test astm c702 sometimes cannot be avoided, for example, in the astm c702 of an aggregate having relatively few large size particles in the sample. Other factors being equal, larger samples will tend to be more representative of the total supply.
Sieve size is identified by its standard designation in Specification E Historical Version s – view previous versions of standard.
