1. SCOPE 1.1
This Standard covers requirements and test methods for closed cell
polyurethane and polyisocyanurate cellular plastic thermal insulation in the
form of flat rigid boards covered on both sides with a facing material and
primarily intended for use in applications where the continuous use temperature
is within the range -60ºC to +93ºC. These rigid boards are not intended to be
used as structural panels. The Standard covers products made with various
facing materials, which impact some physical characteristics. Products
manufactured to this Standard are intended for use as thermal insulation in
building construction. 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 product made using fibreboard, perlite
board, gypsum board, oriented strandboard, or any other rigid board, on one or
both sides (users are referred to ASTM C 1289-98).
