28、rkmanship and Finish10.1 Although all properties of the insulation blanket are notpresented in this specification, it is understood that the insula-tion will essentially be free of defects that adversely affectthermal performance, such as local compressed areas, lowdensity areas, tears and holes.10.

31、izes listed are not always available from all manufacturers. For sizes otherthan those listed, consult manufacturers.BThicknesses of the various mineral fiber insulations available can differ toprovide rated thermal resistance. Products are generally available in a range ofthicknesses from 3 to 12 i
32、n. (75 to 305 mm). Thickness required to attain a ratedperformance shall not exceed that of the cavity into which the material shall beinstalled.CBlanket insulation manufactured to provide a designated thermal resistanceare produced by varying one or more of the factors of density, thickness, or fib

Therefore, blankets having the same designated thermal resis-tance but different manufacturing sources may vary in one or more of thesefactors.C665062they are presumed to be free of excessive tears, rips, holes, andother defects that will adversely affect their performance.11. Sig
34、nificance and Use11.1 This specification applies to products that are used inbuildings. While products that comply with this specificationare used in various constructions, they are adaptable primarily,but not exclusively, to wood frame construction.11.2 Since the property of thermal resistance for
35、a specificthickness of blanket is only part of the total thermal perfor-mance of a building element such as a wall, ceiling, floor, andso forth, this specification states only general classifications forthermal resistance of the fibrous blanket itself. Facings thatprovide additional resistance to wa
36、ter-vapor transfer can affectsystem performance.12. Sampling12.1 Sampling of the insulation shall be in accordance withCriteria C 390. Specific provision for sampling shall be agreedupon between the purchaser and the supplier.13. Test Methods13.1 DimensionsTest in accordance with Test MethodsC 167.1
37、3.2 Thermal Resistance:13.2.1 Test in accordance with Test Method C 177 or TestMethod C 518 at 75 6 2F (24 6 1C) mean temperature. IfTest Method C 518 is used, the manufacturer shall certify thatrecent calibrations have been made.NOTE 1See Guide C 653. The thermal resistance is a function ofmean tem
38、perature. As an option, determine the thermal resistance atadditional mean temperatures as agreed upon by the purchaser and themanufacturer.13.2.2 In case of question, determine referee test values inaccordance with Test Method C 177, with resistances reportedat 75 6 2F (24 6 1C) mean temperature. T
39、he precision andbias of the apparatus used for referee tests must be verified bymeasuring the R-value of a standard reference material of lightdensity thermal insulation obtained from the National Instituteof Standards and Technology.3Determine thermal resistance atthe thickness marked on the produc
40、t if its measured thicknessis equal to or greater than this value. Determine thermalresistance at actual thickness if less than the thickness markedon the product. Always test at a thickness within the designaccuracy limits of the test apparatus. For marked thicknessesappreciably greater than appara
41、tus design, some materials canbe split and both sections tested, but this procedure is oftenundesirable.13.2.3 If the blanket is furnished with adhered facings,remove the facings by a means that provides a surfaceequivalent to the surface that the material would have beforeapplication of the facing.

44、easureof the corrosiveness of mineral-fiber insulation by comparisonto a control.13.8.2 Summary of Test Method:13.8.2.1 Individually sandwich five each of speciallycleaned steel, copper, and aluminum test plates between piecesof insulation. Hold the insulation uniformly against each sideof the test
45、plate with wire screens and rubber bands.13.8.2.2 Sandwich an equal number of cleaned metal testplates between pieces of washed sterile cotton in an identicalmanner.13.8.2.3 Vertically suspend the samples in a humidity testchamber at 95 6 3 % relative humidity and temperature of 1206 3F (49 6 2C) fo
46、r time periods determined by the type ofmetal being tested. Steel is tested for 96 6 2 h. Copper andaluminum are tested for 720 6 5h.13.8.2.4 After the appropriate test period, compare the testplates exposed to the insulation to the control plates exposed tosterile cotton for severity of corrosion.
47、The insulation isconsidered to have passed this test if the corrosion attributed tothe insulation is not significantly worse than that of the washedsterile cotton controls. The criterion for acceptance is prede-termined through the use of non-parametric statistics and a90 % confidence level (a = 0.1
48、0).13.8.3 Significance and Use:13.8.3.1 The fiber composition and the type of binder usedin the manufacture of mineral fiber insulation can sometimescreate a potential for corrosion on certain metals in thepresence of water or water vapor.13.8.3.2 This method is used to determine the relativecorrosi
