BS PD CEN/TS 12390-9:2016描述了两种混凝土的抗冻融剥落试验 用水和氯化钠溶液。它既可以用来比较新的成分，也可以用来 新的混凝土成分与已知的 在当地环境中有足够的性能，或根据某些绝对值评估测试结果 基于当地经验的数值。外推试验结果，以评估不同的混凝土，即新成分或新混凝土 作文，需要专家评估。注:在某些情况下，测试方法可能不适用于测试特殊混凝土e。 g、 高强度 混凝土或透水混凝土。在这些情况下，需要谨慎对待结果。此外，测试 本文件中包含的方法可能无法识别偶尔会出现“弹出”的聚合。三种试验方法得出的结果之间没有确定的相关性。所有的测试都会 清楚地识别不良行为和良好行为，但他们对边缘行为的评估不同。这个 对测试结果应用不同的验收限值，可以对不同程度的缺陷进行评估 暴露严重程度。如果对试验参数进行了合理修改，可能会采取预防措施。 附录A中描述了一些替代应用。交叉引用:EN 12390-2ISO 5725 EN 60751IEC 60751SS 137244:2005购买本文件时可获得的所有当前修改件均包含在购买本文件中。

BS PD CEN/TS 12390-9:2016 describes the testing of the freeze-thaw scaling resistance of concrete both with water and with sodium chloride solution. It can be used either to compare new constituents or new concrete compositions against a constituent or a concrete composition that is known to give adequate performance in the local environment or to assess the test results against some absolute numerical values based on local experiences.Extrapolation of test results to assess different concretes, i.e. new constituents or new concrete compositions, requires an expert evaluation.NOTE In some cases the test methods may not be suitable for testing special concretes e.g. high strength concrete or permeable concrete. In these cases the result needs to be treated with caution. Also, the testing methods included in this document may not identify aggregates that are subject to occasional 'pop-outs'.There is no established correlation between the results obtained by the three test methods. All tests will clearly identify poor and good behaviour, but they differ in their assessment of marginal behaviour. The application of different acceptance limits for test results enables assessment for different degrees of exposure severity. In case of justified modifications of the test parameters, precautions might apply.Some alternative applications are described in Annex A.Cross References:EN 12390-2ISO 5725EN 60751IEC 60751SS 137244:2005All current amendments available at time of purchase are included with the purchase of this document.
