Designation:E220314Standard Specification forDense Thermoplastic Elastomers Used for CompressionSeals,Gaskets,Setting Blocks,Spacers and Accessories1This standard is issued under the fixed designation E2203;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 specification describes products composed of densethermoplastic elastomers that are fabricated into gaskets andaccessories(such as compression seals,setting blocks,spacers,and shims)for use in sealing and glazing applications inbuilding construction.These products are used to seal or serveas components of compression sealing systems between me-chanically restrained surfaces in building construction.1.2 The values stated in metric(SI)units are to be regardedas the standard.The inch-pound values given in parentheses areprovided for information purposes only.1.3 Test Method C1166,as referenced in this specification,should be used to measure and describe the properties ofmaterials,products,or assemblies in response to heat and flameunder controlled laboratory conditions and should not be usedto describe or appraise the fire hazard or fire risk of materials,products,or assemblies under actual fire conditions.However,results of this test may be used as elements of a fire riskassessment that takes into account all of the factors which arepertinent to an assessment of the fire hazard of a particular enduse.1.4 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 requirements prior to use.2.Referenced Documents2.1 ASTM Standards:2C717 Terminology of Building Seals and SealantsC864 Specification for Dense Elastomeric Compression SealGaskets,Setting Blocks,and SpacersC1087 Test Method for Determining Compatibility ofLiquid-Applied Sealants with Accessories Used in Struc-tural Glazing SystemsC1166 Test Method for Flame Propagation of Dense andCellular Elastomeric Gaskets and AccessoriesD395 Test Methods for Rubber PropertyCompression SetD412 Test Methods for Vulcanized Rubber and Thermoplas-tic ElastomersTensionD471 Test Method for Rubber PropertyEffect of LiquidsD573 Test Method for RubberDeterioration in an AirOvenD624 Test Method for Tear Strength of Conventional Vul-canized Rubber and Thermoplastic ElastomersD746 Test Method for Brittleness Temperature of Plasticsand Elastomers by ImpactD792 Test Methods for Density and Specific Gravity(Rela-tive Density)of Plastics by DisplacementD865 Test Method for RubberDeterioration by Heating inAir(Test Tube Enclosure)D925 Test Methods for Rubber PropertyStaining of Sur-faces(Contact,Migration,and Diffusion)D1149 Test Methods for Rubber DeteriorationCracking inan Ozone Controlled EnvironmentD1566 Terminology Relating to RubberD2000 Classification System for Rubber Products in Auto-motive ApplicationsD2137 Test Methods for Rubber PropertyBrittleness Pointof Flexible Polymers and Coated FabricsD2240 Test Method for Rubber PropertyDurometer Hard-nessD3182 Practice for RubberMaterials,Equipment,and Pro-cedures for Mixing Standard Compounds and PreparingStandard Vulcanized Sheets2.2 Other Documents:Rubber Manufacturers Association(RMA)Standard;Rub-ber Handbook,Fourth ed.December 19843Uniform Freight Classification Rules41This specification is under the jurisdiction of ASTM Committee C24 onBuilding Seals and Sealants and is the direct responsibility of Subcommittee C24.73on Compression Seal and Lock Strip Gaskets.Current edition approved Feb.1,2014.Published March 2014.Originallyapproved in 2002.Last previous edition approved in 2008 as E2203-02(2008).DOI:10.1520/E2203-14.2For 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 the Rubber Manufacturers Association,1400 K Street,NW,Washington,DC 20005.4Available from the Western Railroad Association,Department of Services andSupply,Room 1150,222 S.Riverside Plaza,Chicago,IL 60606-5945.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 National Motor Freight Classification Rules53.Terminology3.1 Refer to Terminology C717 for definitions of the fol-lowing terms used in this specification:compound,compres-sion gasket,edge spacer,elastomer,elastomeric,expansiongasket,gasket,hardness,seal,setting block,shim spacer,standard conditions,and spacer.3.2 Refer to Terminology D1566 for definitions of thefollowing terms used in this specification:compression set,ultimate elongation,tear strength,
