1、Designation: C1304 08 (Reapproved 2013)C1304 18Standard 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 revi
2、sion, 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 for subjective determination of the existence, nature
3、, and degree of odorspresent in all types of thermal insulation materials. This test method is not intended to evaluate the air quality aspects that any suchodors may present.1.2 The standard test condition for material evaluated under this test method is 149 6 1.8F (65 6 1C). Standard specification
4、sreferencing this test method may require other test conditions.1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematicalconversions to SI units that are provided for information only and are not considered standard.1.4 This standard d

7、T) Committee.2. Referenced Documents2.1 ASTM Standards:2C168 Terminology Relating to Thermal Insulation3. Significance and Use3.1 Thermal insulating materials that produce objectionable odors could cause discomfort to persons occupying a structureinsulated with such materials. Therefore, an examinat
8、ion to determine the odor potential of a particular insulation is desirable.4. Apparatus4.1 Stainless Steel Containers or Glass Jars, with all-metallic lids with air-tight seals are required. Containers shall not producediscernible odors of their own. The volume of the container shall be 2.5 to 3 ti
9、mes the volume of the test specimen. Transparentcontainers will be wrapped with aluminum foil to eliminate visual bias.NOTE 1See 5.2 for the minimum mass requirement for the test specimen, which influences test container volume.4.2 Oven, capable of maintaining a temperature of 149 6 1.8F (65 6 1C).4
10、.3 Odor Assessment Panel, consisting of five persons who have demonstrated the ability to detect odors both accurately andconsistently. A guideline for selection of panelists is given in ASTM STP 758.34.4 Odor- and Draft-Free Area, where the required oven is immediately accessible.1 This test method

Sample Preparation5.1 Number of TestsUnless otherwise dictated by a specification standard, one specimen of the material is selected at randomfor testing. The sample shall be protected from contamination prior to te
16、sting. One empty container shall be used as a control foreach sample tested.5.2 Specimen SizeTest specimens shall have a minimum mass of 2 oz (57 g). Where applicable, the specimens shall be cutwith a clean knife and tested at the full product thickness. If the product is faced, the facing shall rem
17、ain as an integral part of thetest 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 other detergents could leave a residue that could bias the neutral
18、ity ofthe container.6.2 Insert each specimen into a clean test container and replace the lid. Place the closed specimen containers and the identicalempty control container for 30 6 5 min in the oven controlled at 1496 1.8F (65 6 1C).6.3 The group of five panelists shall be assembled in the test area
19、 prior to tests. The panelists shall write their perceptions downrather than give verbal results that could bias the opinion of others. An individual questionnaire is provided to each panelist.6.4 Panelists shall rate the control container prior to the test specimen container. The control container
20、shall be rated either ashaving no perceptible odor or as having an odor rated as not objectionable and weak. If a greater odor than this is detected, thetest is considered void, and new control and specimen containers shall be prepared.6.5 Each member shall take the container, remove the lid, sniff
21、the specimen for odor, replace the lid, and then pass the containerto the next member in an expedient manner. The container shall be held at a distance of approximately 2 in. from the nose andshall be sniffed for a period of about 5 s. Panelists shall close their eyes to eliminate visual bias. The o
22、dor examination by allmembers shall be completed within 3 min or the specimen shall be placed back in the oven for 15 min before the evaluation iscontinued. The specimen cannot be heated a third time. If all panel members have not completed their evaluation at the end of thesecond 3 min, discard and
23、 begin with a new specimen.6.6 The questionnaire shall request answers to the following questions: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 classified as
24、 objectionable and strong by more than two panel members shallbe considered to have failed the test.8. Report8.1 A test report summarizing panel ratings shall be prepared, stating whether the material passed or failed.8.1.1 Where possible, specify the manufacturer, product type, whether faced or unf
25、aced, lot number, and production date.8.1.2 Was a perceptible odor present? Yes _. No_. If Yes: _.Yes, continue to 8.1.3 and 8.1.4.8.1.3 Odor was objectionable_, pleasant _, otherwise _.8.1.4 Odor was weak _, strong _.9.
