This standard specifies theory of test method for determining capability of resisting sulfate corrode of cement, instrument and equipment, test materials, composition of mortar, test block molding, curing and measurement of test block, calculation and result treatment. This standard comprises two test methods, namely test method for potential expansion character and that for corrosion resistance. Test method for potential expansion character (P method) is applicable to Portland cement and cements of other varieties specified to adopt this method. Test method for corrosion resistance (K method) is applicable to cement specified to adopt this method.
