ASTM D2059/D2059M-03 (2022) PDF

Full title and description

St ASTM D2059/D2059M-03 (2022) — Standard Test Method for Resistance of Zippers to Salt Spray (Fog). This method describes procedures to evaluate corrosion resistance of all types of zippers and their ability to function after exposure in a prescribed salt-spray (fog) atmosphere; results are intended for comparative and acceptance testing of commercial zipper shipments.

Abstract

This standard specifies preparation, exposure, and evaluation procedures for exposing zippers to a salt-spray (fog) environment (referencing Practice B117) and assessing effects of corrosion visually and by measuring crosswise strength and opening/closing forces before and after exposure. It is written to permit use with either SI or inch–pound units and is issued as D2059/D2059M − 03 (reapproved 2022).

Scope

This test method covers determination of the resistance of all zipper types to corrosion and their functional operability after specified durations in a prescribed salt-spray atmosphere. Values in SI and inch–pound units are treated independently. The method is intended for comparative evaluation and commercial acceptance testing rather than for predicting exact field lifetime.

Key topics and requirements

• Exposure in a controlled salt-spray (fog) chamber following Practice B117 procedures.
• Visual evaluation of corrosion products and their effect on operation.
• Measurement of crosswise strength and the force required to open/close the zipper before and after exposure.
• Specimen preparation: assembled zippers or equivalent length of chain with slider (typical specimen length ~150 mm / 6 in.).
• Use of control specimens and, when required, comparative round-robin testing to resolve inter-laboratory differences.
• References to related zipper and textile test terminology standards and procedures (D123, D2050, D2051, etc.).

Typical use and users

Used by zipper manufacturers, accessory suppliers, textile and apparel testing laboratories, quality assurance and incoming inspection teams, procurement/specification writers, and standards bodies for product acceptance and comparative corrosion-resistance evaluation.
