ASTM International Standard Specification for Spray-Applied Rigid Cellular Polyurethane Thermal Insulation ASTM C1029-08

This specification covers the types and physical properties of spray applied rigid cellular polyurethane intended for use as thermal insulation. Spray-applied rigid-cellular polyurethane thermal insulation shall be classified into four type: Type I; Type II; Type III; and Type IV. Spray-applied rigid-cellular polyurethane thermal insulation shall be produced by the catalyzed chemical reaction of polyisocyanates with polyhydroxyl compounds and by the catalyzed polymerization of polyisocyanates. The following test methods shall be performed: thermal resistance; compressive strength; water vapor permeability; water absorption; tensile strength; response to thermal and humid aging; closed cell content; and surface burning characteristics.
