1、Designation: C1304 08 (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, th

2、e 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 deg

3、ree 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).

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 purpor

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

The volume of thecontainer shall be 2.5 to 3 times the volume of the testspecimen. Transparent containers will b

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, th

11、e 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 powd

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.

16、 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 contr

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

18、lid,sniff the specimen for odor, 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 bia

The specimen cannotbe heated a third time. If all panel members have not completedtheir evaluation at the end of the second 3 min, disca

Interpretation of Results7.1 Any sample producing a detectable odor that is classi-fi

Report8.1 A test report summarizing panel ratings shall beprepared, stating whether the material passed or failed.8.1.1 Where possible, specify the manufacturer, producttype, whether faced or
