1.1 本规范涵盖PVC和其他符合要求的有机聚合物涂层钢丝网，由两股聚合物涂层钢丝组成，带镀锌钢或铝合金钢丝的四点倒钩。以下，PVC和其他有机聚合物涂层将被称为聚合物涂层。 1.2 由三类钢丝涂层制成的倒钩钢丝股钢丝如下: 1.2.1 类别1， 由挤压在锌涂层或铝涂层或锌-5上的聚合物涂层组成 % 铝-稀土合金包覆钢丝； 1.2.2 2a类， 由挤出的聚合物涂层组成，并粘附到镀锌或铝涂层或锌-5 % 铝-稀土合金包覆钢丝；和 1.2.3 2b类， 由聚合物涂层组成，该聚合物涂层熔融并粘附在镀锌或铝涂层或锌涂层上- 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 PVC and other conforming organic polymer-coated steel barbed wire consisting of two polymer-coated strands, with four-point barbs of zinc-coated steel or aluminum alloy wire. PVC and other organic polymer coatings hereinafter will be designated as polymer coating. 1.2 Barbed wire strand wire, produced from three classes of wire coatings, is covered as follows: 1.2.1 Class 1, consisting of a polymer coating extruded over zinc-coated or aluminum-coated or zinc-5 % aluminum-mischmetal alloy-coated steel wire; 1.2.2 Class 2a, consisting of a polymer coating extruded and adhered to zinc-coated or aluminum-coated or zinc-5 % aluminum-mischmetal alloy-coated steel wire; and 1.2.3 Class 2b, consisting of a polymer coating fused and adhered to zinc-coated or 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 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.
