21、performance of powder products based on gypsum binder for building purposes. This includes premixed gypsum building plasters for plastering of walls and ceilings inside buildings where they are applied as a finishing material which can be decorated. These products are specially formulated to meet th
22、eir application requirements by the use of additives/admixtures, aggregates and other binders. Gypsum and gypsum based building plasters for manual and mechanical applications are included. This European Standard also applies to gypsum binders both for direct use on site and for further processing i
23、nto gypsum blocks, gypsum plasterboards, gypsum boards with fibrous reinforcement, gypsum fibrous plasterwork and gypsum ceiling elements. Gypsum mortar for internal not load bearing partitions not exposed to water is also included. Calcium sulfate used as binder for floor screeds is not covered by
24、this European Standard. This European Standard defines the reference tests for technical characteristics and provides for the evaluation of conformity of the products covered by this European Standard. Building lime, as calcium hydroxide, can be used as an additional binder together with gypsum bind
25、er. If gypsum binder is the principle active binding component in a plaster then this plaster is covered by this European Standard. If building lime is the principle active binding component in a plaster then the plaster is covered by EN 998-1. 2 Normative references The following referenced documen
