(Specification)Standard Specification for Resilient Wall Base
Standard Specification for Resilient Wall Base
ABSTRACT
This specification covers resilient wall base. These products are manufactured from rubber or thermoplastic materials, or a combination thereof. Wall base is used to provide a functional, as well as decorative border, between walls and floors. This specification does not include rigid products. Wall base shall be of the following types, as specified: type TS - rubber, vulcanized thermoset, type TP - rubber, thermoplastic, and type TV - vinyl, thermoplastic. Wall base shall be one of the following groups, as specified: group 1 - solid, and group 2 - layered. Wall base shall be of the following styles as specified: style A - straight, style B - cove, style C - butt-to, style D - sculptured. The wear layer thickness, flexibility, adjacent surface straining induced by wall base, light resistance, chemical resistance, dimensional stability, height, thickness, and length shall be tested to meet the requirements prescribed.
SCOPE
1.1 This specification covers resilient wall base. These products are manufactured from rubber or thermoplastic materials, or a combination thereof. Wall base is used to provide a functional, as well as decorative border, between walls and floors. This specification does not include rigid products.
1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 The following safety caveat pertains to the test methods portion, Section 12, of this specification: This standard does not purport to address all 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.
