Standard Test Method for Effect of Drycleaning on Buttons
SIGNIFICANCE AND USE
5.1 This test method is useful for determining the change to the listed properties (see 1.1.1 and 1.1.2) and if the changes are acceptable for the intended use. This test may be used for acceptance testing of commercial shipments of buttons.
5.2 If there are differences of practical significance between the reported test results for two laboratories (or more), comparative tests should be performed to determine if there is a statistical bias between them. As a minimum, test samples should be used that are as homogeneous as possible, that are drawn from the material from which the disparate test results were obtained, and that are randomly assigned in equal numbers to each laboratory for testing. The test results for the two laboratories should be compared using a statistical test for unpaired data, at a probability level chosen prior to the testing series. If a bias is found, either its cause must be found and corrected, or future test results for that material must be adjusted in consideration of the known bias.
SCOPE
1.1 This test method is a means of determining the effect of drycleaning on certain physical attributes of buttons. The test method applies to buttons made from plastics, natural materials, cast metal, stamped metal, and electroplated plastic.
1.1.1 The observed attributes of buttons made from plastic and natural materials include: color change, color transfer, solubility, swelling, and loss of finish.
1.1.2 The observed attributes of buttons made of metal and electroplated buttons include: color change, oxidation, and color transfer.
1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
