1.1 本试验方法提供了水硬性水泥砂浆或混凝土在试验条件下水溶性氯化物的取样和分析程序。 1.2 本标准的文本引用了提供解释信息的注释和脚注。这些注释和脚注不应视为本标准的要求。 1.3 以国际单位制或英寸-磅单位表示的数值应单独视为一个标准。在文本中，英寸-磅单位显示在括号中。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。 1.4 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 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。 ====意义和用途====== 4.1 水溶性氯化物（如果含量足够）能够引发或加速嵌入或接触水泥混合物（如砂浆和混凝土）的某些金属材料的腐蚀。氯化物含量以及其他因素可以作为嵌入式金属材料腐蚀可能性的指标。本试验方法用于测定新建筑或现有结构中水泥基混合物中的水溶性氯化物含量。 注1: 水溶性氯化物含量可随时间变化。例如，由于额外的氯化物进入，水溶性氯化物含量可能会增加。或者，由于氯化物结合或浸出，水溶性氯化物含量可能会降低。 4.1.1 试验条件能够影响水溶性氯化物的测定。当将本试验方法的结果与其他试验方法的结果进行比较时，请小心。 4.2 已知硫化物会干扰氯化物含量的测定。高炉矿渣骨料和水泥中含有硫化物硫，其浓度能够产生此类干扰，并产生错误的高测试结果。试验方法中讨论的过氧化氢处理 C114 ，用于消除此类干扰。 4.3 有些骨料含有氯化物，不能用于腐蚀。 使用本试验方法检测此类氯化物。 3.

1.1 This test method provides procedures for the sampling and analysis of hydraulic-cement mortar or concrete for chloride that is water soluble under the conditions of test. 1.2 The text of this standard references notes and footnotes that provide explanatory information. These notes and footnotes shall not be considered as requirements of this standard. 1.3 The values stated in either SI units or inch-pound units are to be regarded separately as a standard. Within the text, the inch-pound 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. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 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. ====== Significance And Use ====== 4.1 Water-soluble chloride, if present in sufficient amount, is capable of initiating or accelerating the corrosion of some metallic materials embedded in or contacting cementitious mixtures such as mortar and concrete. Chloride content, along with other factors, can be indicators for the possibility of corrosion of embedded metallic materials. This test method is used to determine the water-soluble chloride content in cementitious mixtures, either in new construction or existing structures. Note 1: Water-soluble chloride content can vary with time. For example, water-soluble chloride content could increase due to additional chloride ingress. Alternatively, water-soluble chloride content could decrease due to chloride-binding or leaching. 4.1.1 Test conditions are capable of affecting water-soluble chloride determinations. Take caution when comparing results from this test method with those from other test methods. 4.2 Sulfides are known to interfere with the determination of chloride content. Blast-furnace slag aggregates and cements contain sulfide sulfur in concentrations that are capable of such interference and produce erroneously high test results. Treatment with hydrogen peroxide, as discussed in Test Methods C114 , is used to eliminate such interference. 4.3 There are aggregates that contain chloride that is not available for corrosion. Such chloride will be detected by use of this test method. 3
