1 SCOPE

This specification provides a system for specifying significant properties of commonly used polyurethane foams. This specification applies to slab, bonded and molded flexible cellular products. Urethane foam may be generally defined as an expanded cellular product produced by the interaction of active hydrogen compounds. water and isocyanates. This standard does not apply to foam made from vinyl chloride and polyolefin polymers. For specifying vinyl chloride foams use ASTM D1565 (Specification for Flexible Cellular Materials vinyl Chloride Polymers and C+Polynrxs - Open Cell Foam) or ASTM D1667 (Specification for Flexible Cellular Materials vinyl chloride Polymers and Co-Polymers - Closcd Cell Foam). For specifying polyokfin foams like polyethylene foams use ASTM W819 (Specification for Fexible celluar Materials From Polyolefin Plastics).
