3、n-resistant, perpendicu-larly oriented mineral fiber (rock, slag, or glass) roll and sheetinsulation intended for use on flat, curved, or round surfacesoperating at temperatures between 0F (18C) and 1000F(538C). This product (pipe and tank insulation) is typicallyused on nominal 24 in. (610 mm) or g
4、reater diameter surfaces.For specific applications, the actual use temperatures anddiameters shall be agreed upon between the manufacturer andthe purchaser.1.2 The orientation of the fibers within the roll or sheetinsulation is essentially perpendicular to the heated/cooledsurface (parallel to heat
5、flow). 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 re
6、tarders 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 C921 to aid material selection.Although vapor
7、 retarders properties are not part of thisspecification, properties required in Specification C1136 arepertinent to application or performance.1.4 When the installation or use of thermal materials,accessories, and systems may pose safety or health problems,the manufacturer shall provide the user-app
8、ropriate currentinformation regarding any known problems associated with therecommended use for the products of the company and shallalso recommend protective measures to be employed in theirsafe utilization. The user shall establish appropriate safety andhealth practices and determine the applicabi
9、lity of regulatoryrequirements prior to use.1.5 The values stated in inch-pound units are to be regardedas standard. The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.6 This standard does not purport to add
10、ress all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

Materials and Manufacture6.1 CompositionMineral fiber roll or sheet shall be com-posed of rock, slag, or glass processed from the molten stateinto fibrous fo
33、rm, 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 required.NOTE 1The user is advised tha
34、t 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 temperatures above their maximum us
35、e temperature. PracticeC680 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 white Kraft paper, reinforced fiber
36、 glassscrim, and aluminum foil generally known as ASJ (All ServiceJacket).6.2.2.4 All vapor retarder facings shall comply with Speci-fication C1136.6.2.2.5 It is acceptable to specify other kinds of composi-tions or facings6.3 Manufacturing/FabricationMineral (rock, slag, orglass) fiberboard is norm
37、ally 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 adhered to a facing. Thefinished p
38、roduct 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 1:7.1.1 Maximum Use TemperatureTest in accordance with11.1.7.1.2 DensityTest in accordance with 11.2

40、ification C665 in 11.6, the corrosion resulting from theinsulation in contact with steel plates shall be judged to be nogreater than for comparative plates in contact with sterilecotton.7.2.1 The use of Practice C1617 is an acceptable alternativeto the test procedure in 7.3, with the mass loss corro
41、sion rate ofsteel test sample exposed to the unfaced insulation extract notto exceed that of the 5 ppm chloride solution.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
42、satisfy every potentialcorrosion application.7.3 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 25 % by weight in a
43、ccordance with 11.3.1. Non-fibrouscontent is not 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 evide
44、nt upon posttestinspection.7.6 Maximum Exothermic 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. Exceed
45、ing this limit shallconstitute noncompliance to this specification 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 insul
46、ation and facing on surfaces hotter than 450F (232C) mayincrease 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
47、 of the installed insulation material maydecrease. Contact the 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 hav
