PD CEN/TS 12390-9:2016 is a Technical Specification that outlines the procedures for testing the freeze-thaw resistance of hardened concrete with de-icing salts, specifically focusing on the occurrence of scaling. The purpose of this standard is to provide a framework for comparing new constituents or concrete compositions against established ones, and to assess their performance based on numerical values or local experiences.

It is important to note that the test methods described in this document may not be suitable for special types of concrete, such as high strength or permeable concrete. Additionally, these methods may not identify aggregates that are prone to occasional pop-outs. Therefore, caution should be exercised when interpreting the results in such cases.

There is no established correlation between the results obtained from the three test methods described in this standard. While all tests can identify poor and good behavior, they differ in their assessment of marginal behavior. The application of different acceptance limits allows for assessing different degrees of exposure severity. Adjustments to the test parameters may be justified, but precautions should be taken in such cases.

Annex A of the standard provides alternative applications that can be considered.
