The values stated astm c702 each system may not be exact equivalents; therefore, each system shall be used independently of the other. Sieve size is identified by astm c702 standard designation in Specification E Work Item s – proposed revisions of this standard.
astm c702 Historical Version s – view previous versions of standard. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Failure to carefully follow the procedures in this practice could result in providing a non-representative sample to be used in subsequent testing. These techniques are astm c702 to minimize variations in measured characteristics between the test samples selected and the large sample.
The alternative designation astm c702 in parentheses is for information only and does not represent a different standard sieve size.
In these cases, the entire astm c702 sample should be tested. It is the responsibility of astm c702 user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 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.
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.
Substantial differences between the selected test samples sometimes cannot be avoided, for example, in the case of an aggregate having relatively few large size particles in the sample. Combining values from astm c702 two systems may result in non-conformance with the standard. Chance inclusion or exclusion of only one or two particles in the selected astm c702 sample may importantly influence interpretation of the characteristics of the original sample.
ASTM C Standard
The individual test methods provide for minimum amount astm c702 material to be tested. Other factors being equal, larger samples will tend to be more representative of the total supply.
The laws of chance dictate that these few particles may be astm c702 distributed among the reduced size test samples.
