Significance and Use5.1 Coverage charts list the required installed and productin-service parameters of minimum thickness, maximum netcoverage per package, and minimum mass per unit area toachieve each listed therma
19、l performance (R-value) level. Chartinformation corresponds to numerous standard R-value levelsrepresenting common building codes, industry standards, orlegislated requirements (see example in the Appendix X1) andtherefore additional chart columns may be required, i.e.,number of packages per 1 000 f

Chart maximum net cover-ages are based upon net floor area; framing area deducted.Sloped ceilings, HVAC equipment and ductwork, and otherfactors can significan
21、tly influence product coverage and are tobe considered by the manufacturer.6. Procedures6.1 Three procedures can be used to develop coverage chartvalues. The choice of procedure used depends on the end useand the type of insulation material being evaluated and theindividual developing the chart. Reg
22、ardless of which procedureis used, all require thermal conductivity, thickness, and densitymeasurements to have been made before product coverage canbe calculated. The three procedures are as follows:6.1.1 Select an R-value (usually from a standardized list)and determine what settled thickness will
23、be necessary toachieve the desired R-value. The settled thickness can bedetermined by combining apparent thermal conductivity versusdensity data with settled density versus settled thickness datausing Eq 1. An iterative or trial and error solution is usuallyrequired. Alternatively, a settled density
24、 versus R-value rela-tionship can be used to determine required settled density, thensettled thickness.R2value 5 thickness / l (1)wherel = is the apparent thermal conductivity6.1.2 Select a settled thickness and determine a correspond-ing settled density. Once the settled density is known, theappare
25、nt 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 density for coverage chartdevelopment. This method is used for insulation materials thatdo not exhibit significant density change with varyi
26、ng 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 used in equation 2 to determine minimumsettled thickness at each R-value.Minimum settled thickness 5 R2value / thermal resistivity (2)Wherel =

Using one of the proceduresdescribed in 6.1, calculate the minimum settled thickness orR-value for the range selected. Once these values are calcu-lated and listed, along
28、 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 settled density by settled thickness.6.2.1.2 Maximum net coverage per package, ft2(m2), isdetermined by dividing the product net nomina
