SIGNIFICANCE AND USE 5.1 This test method is useful in determining if the loss of color due to light exposure is satisfactory for the intended end-use. 5.2 This test method is considered satisfactory for acceptance testing of commercial shipments because the method has been used extensively in the trade for acceptance testing. 5.2.1 If there are differences of practical significance between reported test results for two laboratories (or more), comparative tests should be performed to determine if their is a statistical bias between them, using competent statistical assistance. As a minimum, the 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. Other materials with established test values may be used for this purpose. The test results from 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 must be adjusted in consideration of the known bias. 5.3 The test method(s) in this standard along with those in Test Methods D2051, D2052, D2054, D2057, D2058, D2059, D2060, D2061, and D2062 are a collection of proven zipper test methods. They can be used as aids in the evaluation of zippers without the need for a thorough knowledge of zippers. The enumerated test methods do not provide for the evaluation of all zipper properties. Besides those properties measured by means of the enumerated test methods there are other properties that may be important for the satisfactory performance of a zipper. Test methods for measuring those properties have not been published either because no practical methods have yet been developed or because a valid evaluation of the information resulting from existing unpublished methods requires an intimate and... SCOPE 1.1 This test method covers the determination of the alteration in shade of the textile portion of zippers when exposed to light, regardless of the materials of manufacture. 1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard. 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.
Abstract
Overview
ASTM D2053-99(2022): Standard Test Method for Colorfastness of Zippers to Light provides a reliable method for determining the alteration in shade (colorfastness) of the textile portion of zippers when exposed to artificial light. This standard is widely used across industries to evaluate whether the loss of color due to light exposure is within acceptable limits for intended end-use applications. Developed by ASTM International, this test method supports quality assurance, product development, and acceptance testing of zippers, regardless of their material of manufacture.
Key Topics
- Colorfastness Determination:
- Evaluates alteration in shade on zipper tapes and chains after exposure to artificial light sources.
- Uses the AATCC Gray Scale for Color Change to assess and rate the degree of fading.
- Sampling Methodology:
- Primary sampling units are drawn randomly from shipping cartons.
- Laboratory sampling units involve taking one zipper at random from each primary unit for testing.
- Testing Procedures:
- Specimens are exposed front-face up with a portion covered, following AATCC Test Method 16 protocols.
- Assessment is based on hours of exposure to light or AATCC fading units, and degree of fading is documented.
- Interlaboratory Comparison:
- Outlines steps if significant discrepancies occur between labs, including statistical assessments and random sample allocation.
- Scope and Limitations:
- Applies to zippers with textile components, independent of specific material types.
- The standard itself does not address every safety, health, or regulatory concern and places that responsibility on the user.
Applications
Adherence to ASTM D2053-99(2022) is essential in various sectors, ensuring zipper performance and durability under light exposure:
- Textile and Apparel Manufacturing:
- Used in product development to verify that zippers meet customer expectations for color retention, particularly in garments and accessories exposed to sunlight or artificial lighting.
- Quality Control in Supply Chains:
- Supports acceptance testing for commercial shipments, fostering consistency and reliability in zipper performance between suppliers and manufacturers.
- Contract and Specification Compliance:
- Enables manufacturers to meet contract requirements related to colorfastness and avoid costly returns or customer dissatisfaction.
- Laboratory Testing and Research:
- Facilitates standardized assessment and reporting for research and development projects involving zipper components.

Practical Value
Adopting ASTM D2053-99(2022) ensures that zippers are evaluated for colorfastness using internationally recognized procedures. This supports product performance, consistency, and compliance throughout the textile and apparel industry. Manufacturers, quality control professionals, and laboratory personnel benefit from a standardized approach to measuring colorfastness to light, reducing risk and enhancing product satisfaction.
