Products h

21、aving a Grade B designation are designed to be used witha heat-up schedule. Failure to use a heat-up schedule with Grade Bproducts may lead to an exothermic reaction. This is dependent onthickness and temperature. Consult the manufacturer or manufacturersliterature for special heat rate consideratio

22、ns.4.2 Binder decomposition at elevated temperature may be alimiting factor in certain applications. Consult the manufac-turer regarding special heat rate considerations.5. Materials and Manufacturer5.1 Composition The mineral fiber insulation for pipesshall be manufactured from mineral substance su

24、TE 2The user is advised that the maximum use temperature offactory-applied facings and adhesives may be lower than the maximumuse temperature of the insulation. The specifier shall ensure that sufficientinsulation thickness is installed so none of these accessory items (facingsand adhesives) are exp

25、osed to temperatures above their maximum usetemperature. The products covered by this standard are predominantlyinorganic in nature. Organic facings, adhesives and binders are also usedin the construction of these products. The resulting composite thereforecould have increased combustibility.6. Phys
