This specification does not applyto flat block, board, duct wrap, or preformed pipe mineral fiberinsulation where the insulation fiber orientation is generallyparallel to the heated/cooled surface (across the heat flow).1.3 For satisfactory performance, properly installed protec-tive vapor
6、retarders must be used in below ambient temperatureapplications to reduce movement of moisture/water vaporthrough or around the insulation towards the colder surface.Failure to use a vapor retarder can lead to insulation and systemdamage. Refer to Practice C 921 to aid material selection.Although va

31、ormation5.1 The type, category, dimensions, and facing shall bespecified by the purchaser. Shot content and delivered densitycertification only if specified by the purchaser.6. Materials and Manufacture6.1 CompositionMineral fiber roll or sheet shall be com-posed of rock, slag, or glass processed fr
32、om the molten stateinto fibrous form, bonded with an organic binder, and theorientation of the fibers within the roll or sheet insulation isessentially perpendicular to the heated or cooled surface(parallel to heat flow).6.2 Facings:6.2.1 The purchaser must specify the insulation facing andtype requ
33、ired.NOTE 1The user is advised that the maximum use temperature of thefacings and adhesives may be lower than the maximum use temperature ofthe insulation.The specifier shall ensure that sufficient insulation thicknessis installed so none of the accessory items (facing and adhesive) areexposed to te
34、mperatures above their maximum use temperature. PracticeC 680 can be used to predict surface temperatures.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 orFSK.6.2.2.3 Laminated w
35、hite 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 It is acceptable to specify other kinds of composi-tions or facings6.3 Manufacturing/FabricationMineral (rock,
36、 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 fiber is
37、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 conductivity,
38、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 no greater
39、 than for compara-tive plates in contact with sterile cotton.NOTE 2There are facing adhesives that can cause corrosion to steelwhen they are in contact with water or water vapor and the steel.Currently, there is no test method available to satisfy every potentialcorrosion application.7.3 Stress Corr
40、osion 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 applicable
41、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 Exothermic Temperatur
42、e 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 this specifi
43、cation and rejection.NOTE 3Organic binders, adhesives, and some facings may thermallydecompose at high temperatures causing an exothermic temperature rise tooccur. A double-layered installation of perpendicularly oriented mineralfiber insulation and facing on surfaces hotter than 450F (232C) mayincr
44、ease the possibility of internal exothermic temperature rise and maydestroy the fiber.7.7 Compressive ResistanceShall be tested in accordancewith 11.8.NOTE 4At conditions above 450F (232C) hot surface temperatures,the compressive resistance of the installed insulation material maydecrease. Contact t
45、he manufacturer for reduced compression resistances atmaximum temperature conditions.7.8 Fungi ResistanceShall be tested in accordance with11.10; growth no greater than that on a comparative item(white birch wood) shall be considered to have passed the testmethod criteria.8.
