Bibliography

This European Standard describes the test methods for binders, composite binders and factory made mixtures for floor screeds based on calcium sulfate specified in EN XXXX-1. This European Standard describes reference test methods. If other than these methods and conditions are used, it is necessary 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.
