Full Name

ASTM E1730 – Standard Specification for Rigid Foam for Use in Structural Sandwich Panel Cores


This specification covers rigid, closed cell, polyurethane and polyisocyanurate thermal insulation for sandwich panels used in shelter construction for exposure to ambient temperatures of −25 to 160 °F (−32 to 71 °C). Painted surfaces of shelters in actual field use reach temperatures of 200 °F (93 °C). The materials in this specification must be capable of withstanding processing, (laminating) temperatures of 230 °F (110 °C).
