1. Scope

1.1 This specification covers high-density cellular rubber
adhered to carpet, rugs, or various substrates for use as a separate
underlay. This standard may also be used as a specification for
separately blown sponges used as carpet underlay.

1.2 This specification provides material and dimensional
requirements and test methods for specific properties of compression set, compression resistance, delamination strength,
and accelerated aging.
NOTE 1—This specification does not include requirements for burning
characteristics. It shall be noted that the Flammable Fabrics Act Regulations
FF1-70, Standard for the Surface Flammability of Carpets and Rugs, and
FF2-70, Standard for the Surface Flammability of Small Carpets and
Rugs,2 may be applicable for carpets and rugs with integral backing of
rubber cellular cushion.

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 limitations prior to use.
NOTE 2—There is no similar or equivalent ISO standard.
