Fecha:
2020-09-10 /Active
Abstract:

This specification covers flexible cellular urethane materials intended for such uses as inserts for furniture cushions, mattresses, and similar applications. The material and dimensional requirements and methods of tests for specific properties of load bearing, compression set, humid age resistance, pounding fatigue resistance, support factor and resilience are prescribed. This specification covers eight grades of flexible cellular material that may be selected for use in accordance with load bearing and general physical properties, four grades based on pounding-fatigue properties, and three grades based on cushioning performance properties.

Scope:

1.1 This specification covers flexible cellular urethane materials intended for such uses as inserts for furniture cushions, mattresses, and similar applications.

1.2 This specification provides material and dimensional requirements and methods of tests for specific properties of load bearing, compression set, humid age resistance, pounding fatigue resistance, support factor and resilience.

1.3 This specification includes references to government regulations for burning characteristics of flexible cellular material used in specified applications.

1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

Note 1: There is no equivalent ISO standard.

1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
