This document describes the test methods for binders for floor screeds based on calcium sulphate specified in EN 13454-1. In addition, some of the described test methods apply for factory made mixtures for floor screeds based on calcium sulphate specified in EN 13813. This document describes reference test methods. If methods and conditions other than these are used, it is important to show that they give results equivalent to those given by the reference methods. In the event of a dispute, only the reference test method is used. This document describes test methods for binders and made mixtures where the principal active component is calcium sulphate.
