1、Designation: C1083 06 (Reapproved 2015)Standard Test Method forWater Absorption of Cellular Elastomeric Gaskets andSealing Materials1This standard is issued under the fixed designation C1083; the number immediately following the designation indicates the year oforiginal adoption or, in the case of r

2、evision, 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 those cellular elastomeric com-pounds that are manufactured in preformed

3、shapes such asgaskets, and that are used as compression seals for glazingpurposes and as sealing materials in other applications inbuilding construction.1.2 The values stated in SI units are to be regarded as thestandard. The values given in parentheses are provided forinformation purposes only.1.3

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 applicabil-ity of regulatory limitations prior to use.2. Referenced Docum

6、 method: cell, compound, compres-sion gasket, elastomer, elastomeric, gasket, glazing, seal, andsealing material.4. Significance and Use4.1 This test method will quantify the water absorptioncharacteristics of cellular elastomeric gaskets and sealingmaterials. It is a test that enables the specifier

7、 to exerciseengineering judgment in the selection of materials.5. Apparatus5.1 Vessel, of potable water of dimensions appropriate topermit proper submergence of the specimens as described inSection 9.5.2 Stand and Clamps, to hold specimens.5.3 Balance, triple-beam, accurate to 0.01 g.5.4 Paper, lint

Sampling and Test Specimens7.1 Sampling:7.1.1 When possible, the manufactured product or a suitablesection thereof s

9、hall be used for the test. Representativesamples of the lot being examined shall be selected at random.7.1.2 When the manufactured product does not lend itself totesting or to the taking of test specimens because of compli-cated shape, small size, metal or fabric inserts, or other reasons,standard t

10、est strips shall be prepared. The standard specimensfor testing shall be as specified in 7.2.2.7.1.3 The manufacturer shall, upon the request of thepurchaser at the time of ordering, furnish sufficient testspecimens prepared in accordance with Practice D3182.7.2 Test Specimens:7.2.1 The test specime

11、n shall be 460 mm (18 in.) long.7.2.2 Test specimens that are to be prepared as described by7.1.2 shall be 460 mm (18 in.) long, 13 mm (12 in.) thick, and25 mm (1 in.) wide.7.2.3 All test specimens shall be made from the samecompound and shall have the same apparent density and stateof cure as the p

12、roduct they represent.7.2.4 This test method requires ten test specimens.8. Conditioning8.1 Condition all test specimens at 21.1 6 1.1C (70 6 2F)for at least 24 h prior to testing.1This test method is under the jurisdiction ofASTM Committee C24 on BuildingSeals and Sealants and is the direct respons

15、19. Procedure9.1 Identify each test specimen and individually weigh andrecord the information.9.2 Secure the test specimens in a vertical position usingstands and clamps. Clamp at both ends of each specimen sothat the specimens are bent in a U-shape.9.3 Submerge only the center 406 mm (16 in.) of th

16、e testspecimens with the bottom of the loop 152 mm (6 in.) belowthe water line, and the cut ends of the specimen out of thewater.9.4 Test specimens shall be submerged in potable water at23.9 6 1.1C (75 6 2F) for a period of 24 h.9.5 Remove the test specimens from the water and blot withlint-free pap

17、er before weighing. The blotting should be donewith as little pressure as possible so that only the surface wateris removed from the specimen.9.6 Weigh each test specimen and record the values.10. Report10.1 Report the following information:10.1.1 Identification of each test specimen.10.1.2 Average

18、weight of test specimens before testing.10.1.3 Average weight of test specimens after testing.10.1.4 Average weight of water absorbed by the test speci-mens.10.1.5 Variation, if any, from the specified test procedure.11. Precision and Bias311.1 The precision and bias calculations for this test metho

19、dare based on the results of four laboratories testing sixmaterials.11.2 The between-laboratory accuracy of this test method inthe determination of water absorption (based on an averageover four laboratories) is 0.78 for the six test materialsevaluated. This means that if the absolute value of thedi

20、fference between two values is greater than 0.78, then 95 %of the time this represents a statistical difference.11.3 Limited information is available on the precision ofthis test method. Only one sample of each material has beentested in four laboratories using this test method. Past experi-ence has

21、 shown that the within-laboratory precision of this testmethod is expected to be less than the between-laboratoryaccuracy.12.
