Classification4.1 Mineral fiber board insulation covered 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 tempera

22、ture, maximumapparent thermal conductivity, minimum compressive resis-tance, maximum linear shrinkage, maximum water vaporsorption, and maximum surface burning characteristics for theinsulations.4.1.1 Category 1No compressive resistance (load-bearing) properties are required.4.1.2 Category 2Minimum

23、compressive resistance (load-bearing) properties are required.4.1.3 Type V, Grade ARequires no heat-up schedule.4.1.4 Type V, Grade BHeat-up schedule isrequired.WarningGrade B may not be suitable for applica-tions requiring hot installation capability at the maximumtemperature indicated. In general,

24、 products having a Grade Bdesignation are designed to be used with a heat-up schedule.Failure to use a heat-up schedule with Grade B products maylead to an exothermic reaction. This is dependent on thicknessand temperature. Consult the manufacturer or manufacturersliterature for special heat rate co
