6. Materials and Manufacture
6.1 Homogeneous Rubber Sheet Floor Covering—The product shall consist of a wear layer and backing. The surface coloring or
mottling shall be uniform throughout the entire thickness of the wear layer. The backing shall be fibrous or foamed rubber and
thoroughly bonded to the wear layer so as not to delaminate under normal use.
6.2 Heterogeneous (Layered) Rubber Sheet Floor Covering—The product shall consist of a wear layer, intermediate layer(s), and
a backing. The surface coloring or mottling shall be uniform throughout the entire thickness of the wear layer, but need not extend
through the intermediate layer(s). The backing shall be fibrous or foamed rubber. The wear layer, intermediate layer(s) and backing
shall be thoroughly bonded so as not to delaminate under normal use.
6.3 Wear Layer:
6.3.1 The polymeric binder of the wear layer shall satisfy the definition of rubber in Terminology D1566, and have been
vulcanized, as defined in Terminology D1566 (under vulcanization), such that it becomes thermoset as defined in Terminology
D883. The wear layer made from this compound shall be resistant to neutral pH cleaners.
6.3.2 The wear layer must have a minimum thickness of 0.040 in. (1.0 mm) when measured in accordance with Test Method F410.
6.3.3 The appearance of the rubber sheet floor covering after removing 0.020 in. (0.51 mm) of the wear layer thickness, shall
compare favorably in appearance with the sheet flooring’s original appearance. The removal of the wear layer may be
accomplished by any suitable method.
6.3.4 The wear layer may have a smooth, embossed, or molded pattern surface.
6.4 Intermediate Layers—The layer(s) may consist of, but not be limited to, rubber, foamed rubber, or other materials, which are
intended to improve the performance characteristics of the product.
6.5 Backings—The composition of the backings shall be fibrous or foamed rubber and may contain other ingredients provided the
resultant backing is suitable for installation on floors above-, on-, or below-grade when installed according to manufacturer’s
installation recommendations.
6.6 Color, Pattern, and Wearing Surface—The color, pattern, and wear layer surface, as applicable, shall be as specified in the
contract or order (see 5.1).
NOTE 1—The colors and patterns that are available are indicated in individual manufacturer’s current catalogs. As manufactured, colors may vary
somewhat in hue or shade from the catalog.
NOTE 2—Where color match is a concern, samples from the manufacturer shall be obtained to verify color acceptability.
7. Performance Requirements
7.1 Hardness—The rubber sheet floor covering shall have a durometer hardness of not less than 85 (Shore, Type A) when tested
in accordance with Test Method D2240. The backing material shall be removed prior to testing and may be accomplished by any
suitable method.
7.2 Modulus at 10 % Elongation—When tested in accordance with Test Method D412 at a rate of 6 in. (152.4 mm)/min, using
a 1 in. (25.4 mm) by 5 in. (127 mm) gage length rectangular specimen, the modulus shall not be less than 300 psi (2.07 MPa).
For molded pattern rubber sheet floor covering, the raised pattern shall be removed by any suitable method. Prior to testing, the
backing material shall be removed and may be accomplished by any suitable method.
F1860 − 21a
7.3 Static Loading—When tested in accordance with Test Method F970, with an applied load of 250 lb (113.4 kg), the residual
indentation shall not be greater than 0.005 in. (0.127 mm).
7.4 Resistance to Chemicals—When tested in accordance with Test Method F925, the rubber sheet floor covering shall have no
more than a slight change in surface dulling, color change or surface attack when exposed to the flowing chemicals:
7.4.1 White vinegar (5 % acetic acid),
7.4.2 Rubbing alcohol (70 % isopropyl alcohol),
7.4.3 Sodium hydroxide solution (5 % NaOH),
7.4.4 Hydrochloric acid solution (5 % HCl),
