1.1本规范涵盖了规范A 906/A 906M中所述的80级和100级合金链式吊索的锻造合金钢起重部件、焊接联轴器和主连杆的要求。 1.2包括两个等级的部件和焊接连接: 1.2.1 80级。 1.2.2 100级。 1.3本规范为性能标准。其他标准适用于这些产品的使用。其中一些标准是:OSHA 1910.184、ASME B30.10和ASME B30.9。 1.4以英寸-磅或国际单位制表示的数值应单独视为标准值。 在文本中，国际单位显示在括号中。每个系统中规定的值不是精确的等价物；因此，每个系统应相互独立使用。合并两个系统的值可能会导致不符合规范。

1.1 This specification covers the requirements for forged alloy steel lifting components and welded coupling and master links for Grade 80 and Grade 100 alloy chain slings as described in Specification A 906/A 906M. 1.2 Two grades of components and welded links are covered: 1.2.1 Grade 80. 1.2.2 Grade 100. 1.3 This specification is a performance standard. Other standards apply to use of these products. Some of these standards are: OSHA 1910.184, ASME B30.10, and ASME B30.9. 1.4 The values stated in either inch-pound or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.
