本文件规定了获取非稳态氯化物迁移系数的程序 规定龄期的硬化混凝土试样（见附录a）。测试程序不需要 考虑混凝土随时间与盐水溶液的任何相互作用。测试结果是耐久性 有关混凝土抗氯离子渗透性的指标。购买本文件时可获得的所有当前修订均包含在购买本文件中。

This document specifies the procedure for obtaining the non-steady-state chloride migration coefficient of specimens of hardened concrete at a specified age (see Annex A). The test procedure does not take into account any interaction of concrete with the saline solution over time. The test result is a durability indicator with respect to the resistance of the concrete investigated against chloride penetration.All current amendments available at time of purchase are included with the purchase of this document.
