Other Requirements8.1 Qualification RequirementsThe following require-ments are generally used for purposes of initial material orproduct qualification:8.1.1 Thermal resistance,8.1.2 Surface burning characteristics,8.1.3 Critical radiant flux,
30、8.1.4 Water-vapor permeance,8.1.5 Water vapor sorption,8.1.6 Odor emission,8.1.7 Corrosiveness, and8.1.8 Fungi resistance.8.2 Inspection RequirementsThe following requirementsare generally used for purposes of acceptance sampling of lotsor shipments of qualified thermal insulation:8.2.1 Dimensional
31、tolerances, and8.2.2 Workmanship.9. Dimensions9.1 The material shall conform to 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 w
32、ill essentially be free of defects that adversely affectthermal performance, such as local compressed areas, lowdensity areas, tears and holes.C665 11210.2 Although the general properties of the facings andmeans for attachment are not included in this specification,they are presumed to be free of ex
33、cessive tears, rips, holes, andother defects that will adversely affect their performance.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,b
34、ut not exclusively, to wood frame construction.11.2 Since the property of thermal resistance 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 for
35、thermal resistance of the fibrous blanket itself. Facings thatprovide additional resistance 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 purch
36、aser and the supplier.13. Test Methods13.1 DimensionsTest in accordance with Test MethodsC167.13.2 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 calibr
37、ations have been made.NOTE 3See Guide C653. The thermal resistance is a function of meantemperature. 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 inaccordan
38、ce with Test Method C177, with resistances reportedat 75 6 2F (24 6 1C) mean temperature. 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
39、Standards and Technology.3Determine thermal resistance atthe thickness marked on the product 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 designa
40、ccuracy limits of the test apparatus. For marked thicknessesappreciably greater than apparatus 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 sur

43、Test Method C1304.13.8 Corrosiveness:13.8.1 ScopeThis method provides a qualitative measureof 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 bet
44、ween piecesof insulation. Hold the insulation uniformly against each sideof the test 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 humid
45、ity testchamber at 95 6 3 % relative humidity and temperature of 1206 3F (49 6 2C) for 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
46、insulation to the control plates exposed tosterile cotton for severity of corrosion. 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-term
47、ined through the use of non-parametric statistics and a90 % confidence level (a = 0.10).13.8.3 Significance and Use:3Contact National Institute of Standards and Technology (NIST), 100 BureauDr., Stop 3460, Gaithersburg, MD 20899-3460.TABLE 1 Dimensions and TolerancesAElement Dimension ToleranceLengt
