Designation:C163011(Reapproved 2016)Standard Guide forDevelopment of Coverage Charts for Loose-Fill ThermalBuilding Insulations1This standard is issued under the fixed designation C1630;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This guide provides information to manufacturers forthe development of a loose-fill thermal insulation productcoverage chart.This guide is limited to developing a coveragechart from density versus thickness,apparent thermal conduc-tivity versus density,and thickness versus area mass relation-ships obtained through product testing.1.2 This guide applies to a wide variety of loose-fill thermalinsulation products including mineral fiber(SpecificationC764),or cellulosic fiber(Specification C739)materials;granular types including vermiculite(Specification C516)andperlite(Specification C549);pelletized products;and any otherinsulation materials that are installed pneumatically or pouredin place.1.3 Coverage charts for loose-fill insulation products arerequired by regulation under the United States Federal TradeCommissions 16 CFR Part 460.Other countries or localgoverning agencies may have coverage chart requirements inaddition to,or that differ from,those presented in this guide;see the Appendix for examples.1.4 The values stated in inch-pound units are to be regardedas standard.The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.5 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and to determine theapplicability of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2C168 Terminology Relating to Thermal InsulationC516 Specification for Vermiculite Loose Fill Thermal In-sulationC549 Specification for Perlite Loose Fill InsulationC739 Specification for Cellulosic Fiber Loose-Fill ThermalInsulationC764 Specification for Mineral Fiber Loose-Fill ThermalInsulationC687 Practice for Determination of Thermal Resistance ofLoose-Fill Building InsulationC1374 Test Method for Determination of Installed Thick-ness of Pneumatically Applied Loose-Fill Building Insu-lationC1574 Guide for Determining Blown Density of Pneumati-callyApplied Loose-Fill Mineral Fiber Thermal InsulationE29 Practice for Using Significant Digits in Test Data toDetermine Conformance with Specifications2.2 Other Referenced Documents:16 CFR Part 460,United States Federal Trade CommissionLabeling and Advertising of Home Insulation33.Terminology3.1 Definitions For definitions of terms used in this guide,see Terminology C168.3.2 Definitions of Terms Specific to This Standard:3.2.1 constant densityThe uniformity in mass per unitvolume of a loose-fill insulation throughout its recommendedthickness installation range.3.2.2 installed thicknessThe thickness,as measured,im-mediately after application of a loose-fill insulation.3.2.3 settled densityThe mass per unit volume of a loose-fill insulation after which time and/or forces have exerted theireffect upon thickness.1This guide is under the jurisdiction of ASTM Committee C16 on ThermalInsulation and is the direct responsibility of Subcommittee C16.23 on Blanket andLoose Fill Insulation.Current edition approved March 1,2016.Published March 2016.Originallyapproved in 2006.Last previous edition approved in 2011 as C1630 11.DOI:10.1520/C1630-11R16.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.3United States Code of Federal Regulations,Title 16,Part 460.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 3.2.4 settled thicknessThe thickness,as measured,afterwhich neither time nor forces effect a measurable change.4.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 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 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.NOTE1Initial instal
