This specification covers material and dimensional requirements for high-density rubber cellular cushion adhered to carpet, rugs, or various substrates intended for use as a separate underlay. However, this specification does not include requirements for burning characteristics. Material covered in this specification comprises Class A and Class B flexible, cellular, high-density rubber. Tests for compression set, compression resistance or compression force deflection, delaminations strength, tensile strength, and accelerated aging shall be performed and shall conform to the requirements specified.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. Scope

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

1.2 This specification provides material and dimensional requirements and test methods for specific properties of compression set, compression resistance or compression force deflection, delamination strength, and accelerated aging. Note 1 - This specification does not include requirements for burning characteristics. It shall be noted that 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, may be applicable for carpets and rugs with integral backing of rubber cellular cushion.

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.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
