This method covers the testing of materials proposed for use as air-entraining admixtures in the field.

The values stated in either SI units or inch-pound units are to be regarded separately as the standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. Some values have only SI units because the inch-pound equivalents are not used in practice.

Note—Sieve size is identified by its standard designation in ASTM E11. The alternative designation given in parentheses is for information only and does not represent a different standard sieve size.
