1.1 本规范涵盖编织前涂覆的聚氯乙烯和其他合格的有机聚合物涂层钢链节织物。以下将聚氯乙烯、聚烯烃和其他有机聚合物涂层称为聚合物涂层。 1.2 由三类钢丝涂层制成的织物如下: 1.2.1 I类 由挤塑在镀锌、镀铝或锌-5上的聚合物涂层组成 % 铝-混合稀土合金涂层，或锌-5 % 铝-混合稀土合金涂层钢丝。 1.2.2 2a级 由挤出的聚合物涂层组成，并粘附在镀锌、铝涂层或锌-5上 % 铝-混合稀土合金涂层钢丝。 1.2.3 2b类 由聚合物涂层熔接并粘附到锌上- 涂层、铝涂层或锌-5 % 铝-混合稀土合金涂层钢丝。 1.3 以英寸-磅单位表示的数值应视为标准。括号中给出的值仅供参考。 1.4 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践，并确定监管限制的适用性。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。

1.1 This specification covers polyvinyl chloride and other conforming organic polymer-coated steel chain-link fabric, coated before weaving. Polyvinyl chloride, polyolefin, and other organic polymer coating hereinafter will be designated as polymer coating. 1.2 Fabric produced from three classes of wire coatings are covered as follows: 1.2.1 Class I consists of polymer coatings extruded over zinc-coated, aluminum-coated, or zinc-5 % aluminum-mischmetal alloy-coated, or zinc-5 % aluminum-mischmetal alloy-coated steel wire. 1.2.2 Class 2a consists of polymer coating extruded and adhered to zinc-coated, aluminum-coated, or zinc-5 % aluminum-mischmetal alloy-coated steel wire. 1.2.3 Class 2b consists of polymer coating fused and adhered to zinc-coated, aluminum-coated, or zinc-5 % aluminum-mischmetal alloy-coated steel wire. 1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are provided for information only. 1.4 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. 1.5 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.
