- Scope
1.1 This specification covers non-asbestos fiber-mat reinforced cementitious backer units manufactured to be dimensionally stable and suitable as either an unfinished substrate (see Note 1) or as a substrate for decoration such as natural stone or tile on walls, floors, or decks in wet and dry areas. It is also suitable to be used as a substrate in the Application of Class PB Exterior Insulation Finish Systems (Practice C 1397
), the Application of Direct-Applied Finish Systems (Practice C 1516 ), and the Application of Exterior Insulation Finish Systems Class PI (Practice C 1535 ). Note 18212;When used as an unfinished substrate, consult the manufacturer''s written installation literature for proper application details.
1.2 This specification is not applicable to asbestos-cement flat sheets (Specification C 220
); non-asbestos fiber cement flat sheets for exterior applications such as claddings, facades, curtain walls, and soffits (Specification C 1186 ); gypsum backing board, coreboard, and shaftliner (Specification C 442 ); water-resistant gypsum backing board (Specification C 630 ); glass mat gypsum backing board (Specification C 1178 ); particle boards (Definitions D 1554 ); and discrete non-asbestos fiber cement interior substrate sheets (Specification C 1288 ). 1.3 Units8212;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.
