Standard Test Method for Durability of Finish of Zippers to Laundering
SIGNIFICANCE AND USE
5.1 Test Method D2051 is useful for testing to determine the effect of repeated laundering on the appearance of the decorative coating of a zipper.
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 test should be performed to determine if there 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 the standard along with those in Test Methods D2052, D2053, D2054, D2057, D2058, D2059, D2060, D2061, and D2062 are a collection of proven 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no practical methods have yet been developed or because a valid evaluation of the information resulting from existing unpublished methods requires an inti...
SCOPE
1.1 This test method covers the determination of the durability of the enamel or other decorative coating of a zipper when subjected to laundering.
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.

Overview
ASTM D2051-14(2022), titled “Standard Test Method for Durability of Finish of Zippers to Laundering,” is a globally recognized standard developed by ASTM International. This test method outlines procedures for assessing the durability and appearance retention of the decorative enamel or coating on zippers after they are subjected to repeated laundering cycles. As laundering can impact both appearance and performance, this standard provides valuable guidance for manufacturers, quality assurance teams, and suppliers aiming to ensure zipper products meet quality expectations throughout their life cycle.
Regular testing ensures that zippers used in various textile and apparel applications maintain their decorative and protective finishes even after repeated washing, safeguarding both product quality and customer satisfaction.
Key Topics
- Purpose and Scope: The standard covers the evaluation of the decorative coating's resistance to physical and chemical actions encountered during laundering. It applies to completely assembled zippers or zipper chains not exceeding 254 mm (10 inches) in length.
- Significance and Use:
- Assesses the effect of repeated laundering on zipper coating appearance.
- Widely adopted in the textile industry for acceptance testing of commercial shipments.
- Facilitates comparison of results between laboratories to ensure consistency using statistical analysis if discrepancies are identified.
- Referenced Test Methods: The test relies on laboratory laundering with controlled conditions, following protocols such as AATCC Method 61 for colorfastness and additional ASTM zipper standards for comprehensive evaluation.
- Sampling and Evaluation:
- Offers guidelines for sampling, testing, and reporting.
- Test results are visually interpreted by examining loss of coating and comparing against agreed standards.
- Compliance and Safety: Users are responsible for adhering to relevant safety, health, and environmental guidelines when applying this method.
Applications
The ASTM D2051-14(2022) test method is invaluable across multiple industries involved in zipper production, garment manufacturing, and quality control. Main applications include:
- Textile and Apparel Manufacturing: Ensures durability and aesthetics of zippers on clothing, uniforms, and accessories subjected to repeated laundering.
- Quality Assurance in Supply Chains: Used as an acceptance test standard to evaluate shipments before market distribution or product use.
- Product Development and R&D: Helps manufacturers identify optimal coatings and finishes that maintain their integrity over the product's lifespan.
- Consumer Goods Testing: Applied by independent testing labs and third-party certifiers to validate supplier claims regarding zipper durability.
- Contractual Agreements: Supports clear communication of quality expectations between buyers and suppliers through objective testing procedures.
Related Standards
ASTM D2051-14(2022) exists within a broader suite of ASTM standards for zipper evaluation and textile testing, which can be jointly referenced for comprehensive product quality analysis:
- ASTM D2052: Colorfastness of Zippers to Drycleaning
- ASTM D2053: Colorfastness of Zippers to Light
- ASTM D2054: Colorfastness of Zipper Tapes to Crocking
- ASTM D2057: Colorfastness of Zippers to Laundering
