1.1This specification pertains to the criteria and tests to be used for determining whether a(n) organic or inorganic processing addition, when used in the recommended amount at the option of the cement producer in the manufacture of hydraulic cements, meets the requirements as prescribed by definition in Specifications C150/C150M, C1157/C1157M, C845/C845M, and C595/C595M. The materials listed in the following former ASTM Specifications shall be considered as meeting the organic processing additions requirements of this specification:
| C150/C150M – 62, for Portland Cement | ||
| C205 – 58 T, for Portland Blast-Furnace Slag Cement | ||
| C340 – 58 T, for Portland Pozzolan Cement | ||
| C358 – 58, for Slag Cement | ||
1.2The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3The following safety hazards caveat pertains only to the test methods described in 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
