1.1 本规范涵盖用于地板、楼梯、运输设备和一般结构用途的碳钢、低合金、高强度低合金和合金钢热轧地板。虽然地板通常在轧制状态下提供，但也可以在热处理状态下提供，具体取决于材料规格。轧制的地板在板的一个表面上有规则的间隔。 1.2 地板的尺寸符合板材、厚板材卷或板材的分类尺寸限制。根据本规范交付的产品的最大厚度为1英寸。[25毫米]。 1.3 在焊接钢材时，先决条件是采用适合钢材等级和预期用途或服务的焊接工艺。 见规范附录X3 A6/A6M 有关焊接性的信息。 1.4 以英寸-磅单位或国际单位表示的数值应单独视为标准值。每个系统中规定的值不一定是精确的等价物；因此，为确保符合标准，每个系统应独立使用，且两个系统的值不得组合。 1.5 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 carbon, low-alloy, high-strength low-alloy, and alloy steel hot-rolled floor plates for flooring, stairways, transportation equipment, and general structural purposes. While it is generally provided in the as-rolled condition, floor plate also may be provided in the heat-treated condition, depending on the material specification. Rolled floor plates have raised figures at regular intervals on one surface of the plate. 1.2 Floor plate is available in dimensions that meet the classification size limits for sheet, heavy thickness sheet coil, or plate. Maximum thickness for product delivered under this specification is 1 in. [25 mm]. 1.3 When the steel is to be welded, it is presupposed that a welding procedure suitable for the grade of steel and intended use or service will be utilized. See Appendix X3 of Specification A6/A6M for information on weldability. 1.4 The values stated in either inch-pound units or SI units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and the values from the two systems shall not be combined. 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.
