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. 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.
