ASTM D3692-89(2021)

4.1?This practice is useful for the selection of zippers that will be compatible with items to be care labeled.

4.2?This practice is useful as a guide for the selection of test methods to evaluate zipper properties that are relevant to care-labeled items.

1.1?This practice provides guidelines to the manufacturer for the selection of zippers to be used in garments and household furnishings that have care labels. The use of this practice will facilitate the selection of a zipper compatible with the end-item requirements. In the absence of complete knowledge of end-item characteristics, it is not possible to stipulate specific universal characteristics for a care label. Therefore following initial selection, the chosen zipper should be tested in a prototype item to confirm its suitability. Zipper properties to be considered are those that may, following refurbishing, be the ones likely to adversely affect the continued use and enjoyment of the item in which the zipper is installed.

1.2?The product characteristics evaluated by this practice are shrinkage, colorfastness, and ironing deformation.

1.3?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.

1.4?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.
