适用范围

1.1 Products that comply with the requirements of this Standard are intended for use as thermal insulation in building construction. This Standard covers requirements and test methods for closed cell polyurethane and polyisocyanurate foam thermal insulation in the form of flat rigid boards covered on both sides with a facing material which impart some physical characteristics. 1.2 This closed cell polyurethane and polyisocyanurate foam thermal insulation is primarily intended for use in applications where the continuous use temperature is within the range -60 °C to +93 °C. 1.3 These rigid boards are not intended to be used as structural panels. 1.4 This Standard covers only products in which the facing material has been bonded to the foam core in the original foam manufacturing process. This Standard does not apply to products using fibreboard, perlite board, gypsum board, oriented strand board, or any other rigid board, as a facing material on one or both sides (users are referred to ASTM C1289, Standard Specification for Faced Rigid Cellular Polyisocyanurate Thermal Insulation Board, for these products). 1.5 The products covered by this standard are classified into six Types based on mechanical properties and three Classes based on water vapour permeance. 1.6 This document does not purport to address all the health and safety aspects associated with its use. Anyone using this Standard has the responsibility to consult the appropriate authorities and to establish health and safety practices, in conjunction with any existing applicable regulatory requirements, prior to its use.
