31、andtype required. (WarningThe user is advised that the maxi-mum use temperature of the facings and adhesives may belower than the maximum use temperature of the insulation. Thespecifier shall ensure that sufficient insulation thickness isinstalled so none of the accessory items (facing and adhesive)
32、are exposed to temperatures above their maximum use tem-perature. Practice C 680 can be used to predict surface tem-peratures.)6.2.2 Typical Facings:6.2.2.1 Fiber glass nonreinforced mat.6.2.2.2 Laminated aluminum foil, reinforced fiber glassscrim, and natural Kraft paper generally known as FRK orFS
33、K.6.2.2.3 Laminated white Kraft paper, reinforced fiber glassscrim, and aluminum foil generally known asASJ (All ServiceJacket).6.2.2.4 All vapor retarder facings shall comply with Speci-fication C 1136.6.2.2.5 Other kinds or compositions of facings may bespecified.6.3 Manufacturing/FabricationMiner
34、al (rock, slag, orglass) fiberboard is normally manufactured with the fiberessentially oriented parallel with the face or a facing. Fiberdirection described in this specification is substantially perpen-dicular to a facing. This construction aligns mineral fiberboardin a way that one end of the cut
35、fiber is adhered to a facing. Thefinished product is wound into rolls or cut into sheets.7. Physical Properties7.1 The perpendicularly oriented mineral fiber roll and sheetthermal insulation shall conform to the following requirementsin Table 1: maximum use temperature, maximum apparentthermal condu
36、ctivity, minimum compressive resistance, watervapor sorption, maximum design density, and maximum indi-ces for surface burning characteristics.7.2 Corrosiveness to SteelWhen tested in accordance with11.6, the corrosion resulting from the insulation in contact withsteel plates shall be judged to be n
37、o greater than for compara-tive plates in contact with sterile cotton. (WarningThere arefacing adhesives that can cause corrosion to steel when they arein contact with water or water vapor and the steel. Currently,there is no test method available to satisfy every potentialcorrosion application.)7.3
38、 Stress Corrosion to Austenitic Stainless SteelWhenspecified, shall be tested and evaluated in accordance with11.9.7.4 Non-fibrous Content (Shot)The average maximumshot content of rock and slag mineral fiber products shall notexceed 30 % by weight in accordance with 11.3.1. Non-fibrouscontent is not
39、 applicable to glass mineral fiber products.7.5 Maximum Use TemperatureWhen tested in accor-dance with 11.1, the insulation with facing shall not warp,flame, or glow during hot surface exposure. No evidence ofmelting or fiber degradation shall be evident upon posttestinspection.7.6 Maximum Exothermi
40、c Temperature RiseWhen testedin accordance with 11.1, the midpoint temperature shall not atany point in time exceed the hot surface temperature by morethan 200F (111C). The 200F criterion applies during heat upas well as steady state conditions. Exceeding this limit shallconstitute noncompliance to
41、this specification andrejection.(WarningOrganic binders, adhesives, and somefacings may thermally decompose at high temperatures causingan exothermic temperature rise to occur. A double-layeredinstallation of perpendicularly oriented mineral fiber insulationand facing on surfaces hotter than 450F (2
42、32C) may increasethe possibility of internal exothermic temperature rise and maydestroy the fiber.)7.7 Compressive ResistanceShall be tested in accordancewith 11.8.NOTE 1At conditions above 450F (232C) hot surface temperatures,the compressive resistance of the installed insulation material maydecrea
43、se. Contact the manufacturer for reduced compression resistances atmaximum temperature conditions.8.
