(Specification)Standard Specification for Inorganic Aggregates for Use in Gypsum Plaster
Standard Specification for Inorganic Aggregates for Use in Gypsum Plaster
ABSTRACT
This specification covers perlite, vermiculite, natural and manufactured sand for use as gypsum plaster aggregates. The materials shall conform to the chemical composition, grading, and density requirements covered in this specification. The materials shall be tested for sieve analysis, density of lightweight aggregate, and water soluble impurities of sand.
SCOPE
1.1 This specification covers perlite, vermiculite, natural and manufactured sand for use as gypsum plaster aggregates.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.3 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.
1.4 The text of this specification references notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the specification.
1.5 This 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.
