BS PD CEN/TS 12390-9:2016 describes the testing of the freeze-thaw scaling resistance of concrete bothwith water and with sodium chloride solution. It can be used either to compare new constituents ornew concrete compositions against a constituent or a concrete composition that is known to giveadequate performance in the local environment or to assess the test results against some absolutenumerical values based on local experiences.Extrapolation of test results to assess different concretes, i.e. new constituents or new concretecompositions, requires an expert evaluation.NOTE In some cases the test methods may not be suitable for testing special concretes e.g. high strengthconcrete or permeable concrete. In these cases the result needs to be treated with caution. Also, the testingmethods 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 willclearly identify poor and good behaviour, but they differ in their assessment of marginal behaviour. Theapplication of different acceptance limits for test results enables assessment for different degrees ofexposure 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 137244:2005
