1.1 This specification covers two types of chemical admixtures to be added to hydraulic cement concrete mixtures for the purpose of producing flowing concrete. The types are as follows: 1.1.1 Type I—Plasticizing, and 1.1.2 Type II—Plasticizing and retarding. 1.2 This specification stipulates tests of a chemical admixture with reference concreting materials or with concrete-making materials proposed for specific work. Unless otherwise specified by the purchaser, the tests shall be made using reference concreting materials. 1.3 If a chemical admixture has been tested and found to comply with the provisions of this specification using reference materials, and is being considered for use with other materials for specific work, additional tests for such use are allowed if agreed upon between the purchaser and the supplier and are allowed to consist of a portion of the tests described herein. 1.4 This specification provides for three levels of testing. 1.4.1 Level 1—During the initial approval stage, proof of compliance with the performance requirements defined in

1.4.2 Level 2—Limited
retesting described in the section relating to general requirements
may be requested at intervals by the purchaser. Proof of compliance
with the requirements of 1.4.3 Level 3—For acceptance
of a lot or for measuring uniformity within or between lots, when
specified by the purchaser, the uniformity and equivalence tests of
the section on Lot Uniformity and Equivalence shall be used.
1.5 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. Some values have only SI units because the inch-pound equivalents are not used in practice.
1.6 The text of this standard
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.
1.7 The following
precautionary caveat pertains only to the test method sections of
this specification: This standard does not
purport to address all of the safety concerns, if any, associated
with its use. It is the responsibility of the user of this standard
to establish appropriate safety and health practices and determine
the applicability of regulatory limitations prior to
use.
