(Specification)Standard Specification for Resilient Stair Treads
Standard Specification for Resilient Stair Treads
ABSTRACT
This specification covers resilient stair treads made of rubber and thermoplastic vinyl for interior use. Treads covered by this specification includes the following types, class, and groups: Type TS, Type TP, Type TV, Class 1, Class 2, Group 1, and Group 2. The material requirements for the tread surface design, nosing style, and color are specified. Some typical nosing styles are illustrated. Treads shall meet the specified performance requirements for: (1) hardness, (2) molded stair tread bonding surface, (3) tread backs, (4) resistance to chemicals for short-term exposure, (5) resistance to heat, and (6) resistance to light. The prescribed dimensional requirements includes tread thickness, length, and depth. The sampling methods for the physical property tests are specified.
SCOPE
1.1 This specification covers resilient treads made of rubber and vinyl for interior use.
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 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 requirements prior to use.
