This specification covers resilient floor covering having a vinyl plastic wear layer with backing intended for use in commercial, light commercial, and residential building applications. Material covered by this specification consists of Types I and II floor covering, which may further be classified according to grade (Grades 1, 2, and 3) and backing classes (Class A, B, and C). the floor covering shall consist of a vinyl plastic wear layer (transparent, translucent, or opaque, with the surface smooth, embossed, or textured with or without valley printing), intermediate layers made of foam and reinforcing materials, and backing (which may be fibrous, nonfoamed plastic, or foamed plastic). Tests for wear layer binder content, wear layer thickness, overall thickness, residual indentation, flexibility, and resistance to chemicals, heat, light, and static load shall be performed and shall conform to the requirements specified.

1.1 This specification covers floor covering having a vinyl plastic wear layer with backing. Products may also contain non-PVC specialty performance top layer(s) or intermediate layer(s), or both.

1.2 Two types of floor covering based on binder content are covered. The floor covering is intended for use in commercial, light commercial, and residential buildings based on serviceability characteristics. General information and performance characteristics that determine serviceability and recommended use are included in this specification.

1.3 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.
