Summary of Guide4.1 This guide provides several procedures for use indeveloping loose-fill product coverage chart values from test-derived, best-fit settled density versus
16、 settled thickness, appar-ent thermal conductivity versus density, and installed thicknessversus mass per unit area relationships. The settled densityversus settled thickness relationship is determined using long-term aging studies or other methods as identified in the materialstandard. The apparent
17、 thermal conductivity relationship is aresult from calculations within Practice C687. The installedthickness versus mass per unit area is determined from TestMethod C1374, Guide C1574, or other procedures as identifiedin the material standard.NOTE 1Initial installed thickness is a coverage chart col

19、ed installed and productin-service parameters of minimum thickness, maximum netcoverage per package, and minimum mass per unit area toachieve each listed thermal performance (R-value) level. Chartinformation corresponds to numerous standard R-value levelsrepresenting common building codes, industry
20、standards, orlegislated requirements (see example in the Appendix X1) andtherefore additional chart columns may be required, that is,number of packages per 1 000 ft2(100m2), and initial installedthickness.5.2 This guide applies to coverage charts for installations inopen, horizontal attic floor spac
21、es. Chart maximum net cover-ages are based upon net floor area; framing area deducted.Sloped ceilings, HVAC equipment and ductwork, and otherfactors can significantly influence product coverage and are tobe considered by the manufacturer.6. Procedures6.1 Three procedures are used to develop coverage
22、 chartvalues. The choice of procedure used depends on the end useand the type of insulation material being evaluated and theindividual developing the chart. Regardless of which procedureis used, all require thermal conductivity, thickness, and densitymeasurements to have been made before product cov
23、erage iscalculated. The three procedures are as follows:6.1.1 Select an R-value (usually from a standardized list)and determine what settled thickness will be necessary toachieve the desired R-value. The settled thickness is deter-mined by combining apparent thermal conductivity versusdensity data w
24、ith settled density versus settled thickness datausing Eq 1. An iterative or trial and error solution is usuallyrequired. Alternatively, a settled density versus R-value rela-tionship is used to determine required settled density, thensettled thickness.R value 5 thickness/ (1)where: = apparent therm
25、al conductivity6.1.2 Select a settled thickness and determine a correspond-ing settled density. Once the settled density is known, theapparent thermal conductivity versus density equation is usedalong with Eq 1 to determine the R-value for the chosen settledthickness.6.1.3 Select a constant settled
26、density for coverage chartdevelopment. This method is used for insulation materials thatdo not exhibit significant density change with varying thick-ness. The apparent thermal conductivity value at that density isused in Eq 1 to determine R-value at chosen thickness, or thethermal resistivity is use

Using one of the proceduresdescribed
28、 in 6.1, calculate the minimum settled thickness orR-value for the range selected. Once these values are calcu-lated and listed, along with settled density, the followingcoverage chart columns values are then calculated.6.2.1.1 Minimum mass per unit area, lb/ft2(kg/m2), isdetermined by multiplying s

30、 netcoverage per package.6.2.1.4 Minimum installed thickness is determined by usingthe installed thickness versus mass per unit area relationship.6.2.2 Round the chart values to the appropriate significantfigures using guidelines provided in Practice E29, UnitedStates FTC 16 CFR Part 460 (Home Insul
