Dimensions9.1 The material shall conform to
36、the standard dimensionsand tolerances prescribed in Table 1.10. Workmanship 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, suc

38、e.11. Significance 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 resist
39、ance for 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 resista
40、nce to water-vapor transfer can affectsystem performance.12. Sampling12.1 Sampling of the insulation shall be in accordance withPractice C390. Specific provision for sampling shall be agreedupon between the purchaser and the supplier.13. Test Methods13.1 DimensionsTest in accordance with Test Method
41、sC167.13.2 Thermal Resistance:13.2.1 Test in accordance with Test Method C177 or TestMethod C518 at 75 6 2F (24 6 1C) mean temperature. IfTest Method C518 is used, the manufacturer shall certify thatrecent calibrations have been made.NOTE 3See Guide C653. The thermal resistance is a function of mean
42、temperature. As an option, determine the thermal resistance at additionalmean temperatures as agreed upon by the purchaser and the manufacturer.13.2.2 In case of question, determine referee test values inaccordance with Test Method C177, with resistances reportedat 75 6 2F (24 6 1C) mean temperature
43、. The 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 pro
44、duct 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 app
