3、osition,dimension, and physical properties of mineral fiber (rock, slag,or glass) semi-rigid and rigid board intended for the use asthermal insulation on surfaces operating at temperatures be-tween 0F (-18C) and 1800F (982C). For specificapplications, the actual temperature limits shall be agreed up
4、onbetween the supplier and the purchaser.1.2 For satisfactory performance, properly installed protec-tive vapor retarder or barriers shall be used on below ambienttemperature applications to reduce movement of water throughor around the insulation towards the colder surface. Failure touse a vapor re
5、tarder or barrier can lead to insulation and systemdamage. Refer to Practice C921 to aid material selection.Although vapor retarder properties are not part of thisspecification, properties required in Specification C1136 arepertinent to applications or performance.1.3 The orientation of the fibers w

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.
