Classification4.1 Mineral fiber board insulation cove

22、red by this specifi-cation shall be classified into seven types with two grades forType V and two categories, shown in Table 1. This classifica-tion is based upon the maximum use temperature, maximumapparent thermal conductivity, minimum compressiveresistance, maximum linear shrinkage, maximum water

24、4 Type V, Grade BHeat-up schedule is required.WarningGrade B may not be suitable for applicationsrequiring hot installation capability at the maximum tempera-ture indicated. In general, products having a Grade B designa-tion are designed to be used with a heat-up schedule. Failure touse a heat-up sc

25、hedule with Grade B products may lead to anexothermic reaction. This is dependent on thickness andtemperature.
