1、Designation: C 1304 95 (Reapproved 2001)Standard 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,
2、the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) 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
3、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 referen
4、cing this test method may require othertest conditions.1.3 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
5、 of regulatory limitations prior to use.1.4 The values stated in inch-pound units are to be regardedas the standard. The values given in parentheses are forinformation only.2.

6、nsulating 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
7、-metallic lids with air-tight seals are recommended. Containersshall not produce discernible odors of their own. The volume ofthe container shall be 2.5 to 3 times the volume of the testspecimen. Transparent containers shall be wrapped with alu-minum foil to eliminate visual bias.NOTE 1See 5.2 for t
8、he 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 gui
9、deline 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. Th
10、e 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
11、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 otherdeterge
12、nts 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 the ovencontrolled at 1496 1.8F (65 6 1C).6.3 The group of
13、 five panelists shall be assemblied in thetest area prior to tests. The panelists are reminded to write theirperceptions down rather than give verbal results that could biasthe opinion of others. An individual questionnaire is providedto each panelist.6.4 Panelists shall rate the control container p
14、rior 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 specimen1This test method is under the jurisd

17、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 members shall be completed within 3min or the specimen shal
18、l 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.6.6 The questionnaire shall request answers to the follow
19、ingquestions: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 more than two panelmembers shall be considered to have
20、failed the test.8. Report8.1 A test report summarizing panel ratings shall be pre-pared, stating whether the material passed or failed.8.1.1 Where possible, specify the manufacturer, producttype, whether faced or unfaced, lot number, and productiondate.8.1.2 Was a perceptible odor present? Yes _. No
21、_. IfYes: _.8.1.3 Odor was objectionable_, pleasant _, other-wise _.8.1.4 Odor was weak _, strong _.9.
