Designation:C130408(Reapproved 2013)Standard Test Method forAssessing the Odor Emission of Thermal InsulationMaterials1This standard is issued under the fixed designation C1304;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 test method covers a laboratory procedure forsubjective determination of the existence,nature,and degree ofodors present in all types of thermal insulation materials.Thistest method is not intended to evaluate the air quality aspectsthat any such odors may present.1.2 The standard test condition for material evaluated underthis test method is 149 6 1.8F(65 6 1C).Standardspecifications referencing this test method may require othertest conditions.1.3 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.1.4 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 limitations prior to use.2.Referenced Documents2.1 ASTM Standards:C168 Terminology Relating to Thermal Insulation23.Significance and Use3.1 Thermal insulating materials that produce objectionableodors could cause discomfort to persons occupying a structureinsulated with such materials.Therefore,an examination todetermine the odor potential of a particular insulation isdesirable.4.Apparatus4.1 Stainless Steel Containers or Glass Jars,with all-metallic lids with air-tight seals are required.Containers shallnot produce discernible odors of their own.The volume of thecontainer shall be 2.5 to 3 times the volume of the testspecimen.Transparent containers will be wrapped with alumi-num foil to eliminate visual bias.NOTE1See 5.2 for the minimum mass requirement for the testspecimen,which influences test container volume.4.2 Oven,capable of maintaining a temperature of 149 61.8F(65 6 1C).4.3 Odor Assessment Panel,consisting of five persons whohave demonstrated the ability to detect odors both accuratelyand consistently.A guideline for selection of panelists is givenin ASTM STP 758.34.4 Odor-and Draft-Free Area,where the required oven isimmediately accessible.5.Sample Preparation5.1 Number of TestsUnless otherwise dictated by a speci-fication standard,one specimen of the material is selected atrandom for testing.The sample shall be protected fromcontamination prior to testing.One empty container shall beused as a control for each sample tested.5.2 Specimen SizeTest specimens shall have a minimummass of 2 oz(57 g).Where applicable,the specimens shall becut with a clean knife and tested at the full product thickness.If the product is faced,the facing shall remain as an integralpart of the test specimen.6.Procedure6.1 The test containers shall be washed,thoroughly rinsed,and completely dried prior to use.Laboratory-grade powderdetergent is satisfactory for this purpose.Be advised that otherdetergents could leave a residue that could bias the neutrality ofthe container.6.2 Insert each specimen into a clean test container andreplace the lid.Place the closed specimen containers and the1This test method is under the jurisdiction ofASTM Committee C16 on ThermalInsulation and is the direct responsibility of Subcommittee C16.31 on Chemical andPhysical Properties.Current edition approved Sept.1,2013.Published January 2014.Originallyapproved in 1995.Last previous edition approved in 2008 as C130408.DOI:10.1520/C1304-08R13.2For 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.3“Guidelines for the Selection and Training of Sensory Panel Members,”ASTMSTP 758,ASTM,1981.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 identical empty control container for 30 6 5 min in the ovencontrolled at 1496 1.8F(65 6 1C).6.3 The group of five panelists shall be assembled in the testarea prior to tests.The panelists shall write their perceptionsdown rather than give verbal results that could bias the opinionof others.An individual questionnaire is provided to eachpanelist.6.4 Panelists shall rate the control container prior to the testspecimen container.The control container shall be rated eitheras having no perceptible odor or as having an odor rated as notobjectionable and weak.If a greater odor than this is detected,the test is considered void,and new control and specimencontainers shall be prepared.6.5 Each member shall take
