This specification covers the requirements for the compound and physical characteristics of homogeneous (Type I) and layered (Type II) rubber sheet floor covering with backing. Both types shall be fibrous and foamed rubber, and may also contain intermediate layers. They may either have smooth, embossed, or molded pattern surfaces, and shall not contain asbestos. They shall be tested on, and conform accordingly to the following requirements: chemical composition; hardness; modulus of 10 % elongation; static load limit; resistance to chemicals such as white vinegar, rubbing alcohol, sodium hydroxide solution, hydrochloric acid solution, sulfuric acid solution, household ammonia solution, and household bleach; resistance to heat; resistance to light; width and length; and base, wear layer, and overall thicknesses.

1.1 This specification covers the requirements for the compound and physical characteristics of rubber sheet floor covering having a rubber wear layer with backing. Products may also contain intermediate layers.

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

1.3 The following precautionary statement pertains only to the test method portion, Section 9, 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.
