39、tolerances prescribed in Table 1.10. Workmanship and Finish10.1 Although all properties of the insulation blanket are not presented in this specification, it is understood that the insulationwill essentially be free of defects that adversely affect thermal performance, such as local compressed areas
40、, low density areas,tears and holes.10.2 Although the general properties of the facings and means for attachment are not included in this specification, they arepresumed to be free of excessive tears, rips, holes, and other defects that will adversely affect their performance.11. Significance and Us
41、e11.1 This specification applies to products that are used in buildings. While products that comply with this specification are usedin various constructions, they are adaptable primarily, but not exclusively, to wood frame construction.C665 17311.2 Since the property of thermal resistance for a spec
42、ific thickness of blanket is only part of the total thermal performanceof a building element such as a wall, ceiling, floor, and so forth, this specification states only general classifications for thermalresistance of the fibrous blanket itself. Facings that provide additional resistance to water-v
43、apor transfer can affect systemperformance.12. Sampling12.1 Sampling of the insulation shall be in accordance with Practice C390. Specific provision for sampling shall be agreed uponbetween the purchaser and the supplier.13. Test Methods13.1 DimensionsTest in accordance with Test Methods C167.13.2 T
44、hermal Resistance:13.2.1 Test in accordance with Test Method C177 or Test Method C518 at 75 6 2F (24 6 1C) mean temperature. If TestMethod C518 is used, the manufacturer shall certify that recent calibrations have been made.NOTE 3See Guide C653. The thermal resistance is a function of mean temperatu
45、re.As an option, determine the thermal resistance at additional meantemperatures as agreed upon by the purchaser and the manufacturer.13.2.2 In case of question, determine referee test values in accordance with Test Method C177, with resistances reported at 756 2F (24 6 1C) mean temperature. The pre
46、cision and bias of the apparatus used for referee tests must be verified by measuringthe R-value of a standard reference material of light density thermal insulation obtained from the National Institute of Standardsand Technology.3 Determine thermal resistance at the thickness marked on the product
47、if its measured thickness is equal to orgreater than this value. Determine thermal resistance at actual thickness if less than the thickness marked on the product. Alwaystest at a thickness within the design accuracy limits of the test apparatus. For marked thicknesses appreciably greater than appar
48、atusdesign, some materials can be split and both sections tested, but this procedure is often undesirable.13.2.3 If the blanket is furnished with adhered facings, remove the facings by a means that provides a surface equivalent to thesurface that the material would have before application of the fac
