1.1 This specification covers various grades of anhydrous calcined gypsum known as gypsum Keene's cement, designed for use in the base and finish coats of gypsum plaster. Note 1: The setting time is accelerated by the addition of
other materials.
Note 2: Keene's cements are generally available as
quick-setting and standard-setting types. However, various grades
of gypsum Keene's cement of different fineness and setting time are
available. Grades intended for use in scagliola castings and other
special purposes should conform to the requirements of this
specification in all respects except fineness and setting
time.
1.2 The values stated in either inch-pound or SI (metric) units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system shall be used independently of the other. Values from the two systems shall not be combined. 1.3 The text of this standard references notes and footnotes that provide explanatory material. These notes and footnotes shall not be considered as requirements of the standard. 1.4 The following safety hazards caveat pertains only to the test method in the appendix 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. |
