1、Designation: D 6840 02 (Reapproved 2007)Standard Test Method forEffect of Drycleaning on Buttons1This standard is issued under the fixed designation D 6840; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision.

2、 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 is a means of determining the effect ofdrycleaning on certain physical attributes of buttons. The testmethod appli

Terminology3.1 DefinitionsFor definitions of terms used in this testmethod, refer to Terminologies D 123, D 5497, and D 3136.4. Summary of Test Method4.1 Specimens are sewn onto fabric and subjected to com-mercial dry cleaning.

7、The dry cleaned specimens are measuredand visually compared to an original specimen.5. Significance and Use5.1 This test method is useful for determining the change tothe listed properties (see 1.1.1 and 1.1.2) and if the changes areacceptable for the intended use. This test may be used foracceptanc

8、e testing of commercial shipments of buttons.5.2 If there are differences of practical significance betweenthe reported test results for two laboratories (or more), com-parative tests should be performed to determine if there is astatistical bias between them. As a minimum, test samplesshould be use

The test results for thetwo laboratories should be compared using a statistical test forunpaired d

If a bias is found, either its cause must be found andcorrected, or future test results for that material must beadjusted in consideration of the known bias.6.

18、nside the bag. Close the bag by anyconvenient means.NOTE 1Each button style, size and color should be tested in a separatebag.8.1.4 Dryclean the specimens in the bag as directed inProcedure for Drycleaning, Test Method D 2724, 10.1 through10.3.8.1.5 Repeat the drycleaning procedure through two addi-
