1、Designation: C 1304 08Standard Test Method forAssessing the Odor Emission of Thermal InsulationMaterials1This standard is issued under the fixed designation C 1304; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last r
2、evision. 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 pres
3、ent 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 meth

It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limi

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.
7、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
8、alumi-num foil to eliminate visual bias.NOTE 1See 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 abi
9、lity 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 sp
10、ecimen 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 sha
11、ll 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
12、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 theidentical empty control container for 30 6 5 min in
13、 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 perceptions1This test method is under the jurisdiction ofASTM Committee C16 on ThermalInsulation and is the direct responsibility of Subcommit

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 eithe
17、ras 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 the container, remove the lid,sniff the specimen for odor,
18、replace the lid, and then pass thecontainer to the next member in an expedient manner. Thecontainer shall be held at a distance of approximately 2 in.from the nose and shall be sniffed for a period of about 5 s.Panelists shall close their eyes to eliminate visual bias. Theodor examination by all mem
19、bers shall be completed within 3min or the specimen shall be placed back in the oven for 15min before the evaluation is continued. The specimen cannotbe heated a third time. If all panel members have not completedtheir evaluation at the end of the second 3 min, discard andbegin with a new specimen.6
20、.6 The questionnaire shall request answers to the followingquestions:6.6.1 Was an odor perceptible?6.6.2 Was the odor objectionable or otherwise?6.6.3 Was the odor weak or strong?7. Interpretation of Results7.1 Any sample producing a detectable odor that is classi-fied as objectionable and strong by
