This specification covers the requirements for the compound and physical characteristics of homogeneous (Type I) and layered (Type II) rubber sheet floor covering without backing. The floor coverings 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 without backing.

1.2 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.

1.3 The following precautionary statement pertains only to the test method portion, Section 10, 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
