1.1 本规范涵盖了用于制造铁丝网围栏织物和马歇尔耐张钢丝的金属涂层碳钢丝。涵盖三种类型的涂层: 1.1.1 I型- 镀铝（渗铝）， 1.1.2 II型- 镀锌，以及 1.1.3 III型- 锌-5 % 铝混合稀土（Zn-5Al-MM）合金涂层。 1.2 本规范中由钢丝编织而成的链环织物由规范单独涵盖 A491 对于I型， A392型 对于II型，以及 F1345 对于类型III。 1.3 本规范中使用钢丝制造的马塞尔张力钢丝在规范中单独涵盖 A824 和 F1664 . 1.4 本规范不包括用于规范的电线 A392型 当铁丝网生产商在编织过程后涂覆涂层时。 1.5 以英寸-磅为单位的数值应视为标准值。括号中给出的值仅供参考。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）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 metallic-coated carbon steel wire used in the manufacture of chain-link fence fabric and marcelled tension wire. Three types of coatings are covered: 1.1.1 Type I— Aluminum-coated (aluminized), 1.1.2 Type II— Zinc-coated (galvanized), and 1.1.3 Type III— Zinc-5 % Aluminum-Mischmetal (Zn-5Al-MM) alloy-coated. 1.2 The chain-link fabric woven from wire in this specification is covered separately by Specifications A491 for Type I, A392 for Type II, and F1345 for Type III. 1.3 The marcelled tension wire manufactured from wire in this specification is covered separately in Specifications A824 and F1664 . 1.4 This specification does not cover the wire used for Specification A392 when the chain-link fence producer applies the coating after the weaving process. 1.5 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are provided for information only. 1.6 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.
