This European Standard defines and gives the specifications of supersulfated cement and its constituents. The definition of supersulfated cement includes the proportions in which the constituents are to be combined to produce products in accordance with this standard. The definition also includes requirements the constituents have to meet and the mechanical, physical, chemical including heat of hydration requirements. This standard also states the conformity criteria and the related rules. In addition to the specified requirements, an exchange of additional information between the cement manufacturer and user may be helpful. The procedures for such an exchange are not within the scope of this standard but should be dealt with in accordance with national standards or regulations or may be agreed between the parties concerned. The word "cement" in this standard is used to refer only to supersulfated cement unless otherwise specified. This standard differs from DIN EN 15743:2010-04 as follows: a) Clause 6 and Annex ZA have been brought in line with the Construction Products Regulation. The responsible German body is Working Committee NA 005-07-13 AA "Zement, SpA zu Teilbereichen von CEN/TC 51 und ISO/TC 74" ("Cement, Mirror Committee of parts of CEN/TC 51 and ISO/TC 74") of DIN Standards Committee Building and Civil Engineering (NABau).
