本标准印发的是修订的A416/A416M标准，后面的数字表明标准发行时间或最新的的修订时间，圆括号中的数字表明上次修订时间，设成上标的数字标明是从修订后编辑上的改变。

本标准已被国防部相关机构批准采用。

1、范围

1（1本规范包含两种和两个级别的7股未涂层的用于预应力混凝土的钢绞线。

这两种钢绞线分别是低松弛的和应力全释放的（普通松弛）。

低松弛钢绞线被称为标准型，应力释放的钢绞线一般不予以提供除非特别需要，或者购买者和生产者有协议。

250级和270级都有最小的强度要求分别是1725（ksi）MPa和1860MPa（270ksi），各以其级别命名。

（2在英制体系和SI体系中两者的指标都认为是标准的，在本文内，英制指标1

出现在括号内。

由于两种体系的指标并不是完全等价的，因此，各自的体系必须独立使用。

混合使用两种指标可能导致使用本规范时没有一致性。

1（3提供者要求使用的预应力钢绞线应用于地下锚定装置时要特别要求15.2mm（0.6-in）直径的钢绞线。
