(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 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 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.

than 0.030-in. (0.76 mm) thick, shall be recessed into and adhered to the top surface of a smooth surface tread portion to form a
continuous flat surface overall. Each strip shall run the full length of the treads and shall be parallel to the nose of the tread. The
front edge of the first strip shall be not more than 1 in. (25.4 mm) from the nose of the step or landing. If a second strip is used,

6.2.4 Group 2, Contrasting Color for Visually Impaired—The tread shall contain a strip of contrasting color of either the same
material or an abrasive material.
6.3 Nosing Style—Nosing style shall be as specified (see Figs. 1-3 for some typical styles).
6.4 Color—According to manufacturer’s latest catalogs, and actual samples. Sample color may vary with age and storage
conditions.
