Designation:C164214Standard Practice forDetermining Air Leakage Rates of Aerosol Foam Sealantsand Other Construction Joint Fill and Insulation Materials1This standard is issued under the fixed designation C1642;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.Scope*1.1 This practice is intended to determine the air leakagerate of aerosol foam sealants as measured in a standardized jig.This practice provides a procedure for preparing the testapparatus and further describes the application of aerosol foamsealant and other joint fillers to the apparatus prior to conduct-ing Test Method E283.1.2 This practice allows testing laboratories to quantify theair leakage rate of aerosol foam sealants or joint fillingproducts using Test Method E283 and reporting the data inL/(s m2)according to Practice E29.1.3 This practice is used in conjunction with Test MethodE283.Although Test Method E283 is a laboratory test methodused with fenestration products,individuals interested in per-forming field air leakage tests on installed units shouldreference Test Method E783 and AAMA 502.1.4 Aerosol foam sealants are used for a variety of end useapplications generally intended to reduce air leakage in thebuilding envelope.1.5 Insulating type materials also will be found suitable forevaluation with this practice.1.6 There are no other known practices or test methods thatspecify the preparation of the assemblies used to determine theair leakage rate of gap filling sealants,dry preformed foams orinsulations.1.7 The values given in SI units are the standard.Theinch-pound units in parentheses are for information only.1.8 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 determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2C717 Terminology of Building Seals and SealantsC1330 Specification for Cylindrical Sealant Backing for Usewith Cold Liquid-Applied SealantsC1536 Test Method for Measuring the Yield for AerosolFoam SealantsC1620 Specification for Aerosol Polyurethane and AerosolLatex Foam SealantsE29 Practice for Using Significant Digits in Test Data toDetermine Conformance with SpecificationsE283 Test Method for Determining Rate of Air LeakageThrough Exterior Windows,Curtain Walls,and DoorsUnder Specified Pressure Differences Across the Speci-menE783 Test Method for Field Measurement of Air LeakageThrough Installed Exterior Windows and Doors2.2 Other Standards:AAMA 502 Voluntary Specification for Field Testing ofNewly Installed Fenestration Products3ISO/IEC 17025 General requirements for the competence oftesting and calibration laboratories43.Terminology3.1 Definitions:3.1.1 air barrierthe assembly of material(s)used in build-ing construction to reduce or retard the uncontrolled passage ofair into and out of the building.3.1.2 exfiltrationair flow direction from building interiortoward exterior.3.1.3 infiltrationair flow direction from building exteriortoward interior.1This practice is under the jurisdiction of ASTM Committee C24 on BuildingSeals and Sealants and is the direct responsibility of Subcommittee C24.61 onAerosol Foam Sealants.Current edition approved Sept.15,2014.Published November 2014.Originallyapproved in 2007.Last previous edition approved in 2007 as C1642-07.DOI:10.1520/C1642-14.2For 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.3Available from American Architectural Manufacturers Association(AAMA),1827 Walden Office Square,Suite 550,Schaumburg,IL 60173-4268,http:/www.aamanet.org.4Available from American National Standards Institute(ANSI),25 W.43rd St.,4th Floor,New York,NY 10036,http:/www.ansi.org.*A Summary of Changes section appears at the end of this standardCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 3.1.4 preformed dry foam materialany cellular productdesigned for filling construction joints to resist air leakage.3.1.5 preformed pre-compressed tapesany cellular tapesupplied compressed from its fully expanded shape and de-signed for filling construction joints to resist air leakage.3.1.6 rough opening gapthe open space between thebuilding frame and the fenestration product.3.1.7 test effective areais located at and comprised of gapsbetween aluminum rectangular tubing with each gap havingdimensions of 9.5-mm(0.375-in.)by 864-mm(34-in.)long.Asingle gap area is 0.008 m2(12.75 in.2).The total effective areaof all five ga
