1. Scope

1.1 This specification covers discrete non-asbestos fiber-cement sheets manufactured to be dimensionally stable and suitable for decoration as paint, wallpaper, natural stone, tile, or resilient flooring in internal wet and dry areas.

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 and coreboard (Specification C 442), water-resistant gypsum backing board (Specification C 630), glass mat gypsum backing board (Specification C 1178), particle boards (Definitions D 1554), fiber mat cement boards (Specification C 1325 and ANSI A118.9), or cement-bonded particleboards (Specification BS 5669: Part 4) and (ISO 8335).

1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
