Standard Specification for Air-Entraining Admixtures for Concrete
1.1 This specification covers materials proposed for use as air-entraining admixtures to be added to concrete mixtures in the field.
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as 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.
1.3 The text of this specification references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.
