1.1 本规范涵盖了碳钢和合金钢线材以及线圈或矫直和切割长度的无涂层粗圆线材的一般要求。 1.2 如有冲突，应以采购订单、图纸、个别规范和本通用规范中的要求为准。 1.3 以SI单位或英寸-磅单位表示的值应单独视为标准值。每个系统中陈述的值可能不完全等同；因此，每个系统应独立使用。合并两个系统的值可能导致不符合标准。在正文中，英寸-磅单位显示在括号中。 1.4 本国际标准是根据世界贸易组织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的标准化原则制定的技术性贸易壁垒委员会。

1.1 This specification covers general requirements for carbon and alloy steel wire rods and uncoated coarse round wire in coils or straightened and cut lengths. 1.2 In case of conflict, the requirements in the purchase order, on the drawing, in the individual specification, and in this general specification shall prevail in the sequence named. 1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. Within the text, inch-pound units are shown in brackets. 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.
