D3574-03 Standard Test Methods for Flexible Cellular Materials — Slab, Bonded, and Molded Urethane Foams

1. Scope

1.1 These test methods apply to slab, bonded, and molded flexible cellular products known as urethane foams. Urethane foam may be generally defined as an expanded cellular product produced by the interaction of active hydrogen compounds, water, and isocyanates.

1.2 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.

1.3 The values stated in SI units are to be regarded as standard.

Note 1—There is no equivalent ISO standard, however certain test methods in this standard have similar or equivalent ISO standards and are listed in the Scope of the individual test method sections.
