This European Standard specifies a test method which provides information on how an aggregate behaves when it is subjected to the cyclic action of freezing and thawing.NOTE: The stresses on aggregates due to frost depend, amongst other factors, on the degree of water saturation as well as the rate of cooling.The results provide a means for assessing an aggregate's resistance to this form of weathering.The test is applicable to aggregates having a particle size between 4 mm and 63 mm.
