Part 1: Definitions and requirements
Part 2: Test methods This document specifies binders, composite binders and factory made mixtures where the principal active constitu-ent is calcium sulfate. The requirements in EN 13454-1 on binders and composite binders are based on the results of tests according to EN 13454-2.
The requirements on factory made mixtures for floor screeds based on calcium sulfate are in accordance with
EN 13813. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following coun-tries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Esto-nia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.

1 Scope This document applies to calcium sulfate binders and composite binders made of calcium sulfate used for the manufacture of floor screeds for interior use in buildings. It also includes requirements for factory made mixtures made of calcium sulfate used for the manufacture of floor screeds which are given in EN 13813. This document does not cover the application of floor screeds. Floor screeds made with products covered by this document may contribute to thermal and sound insulation and fire protection of the floor. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

With respect to the manufacturing methods, factory made mixtures shall be suitable for application in one of the three consistencies: stiff, highly plastic or flowing (see 6.9). If calcium sulfate binders or calcium sulfate composite binders, as specified in this document, are used for the manufacture of factory made mixtures, the tests specified in EN 13454-2 for determination of the pH value and for determination of shrinkage and swelling need not to be carried out. Factory made mixtures can be produced and delivered as:

The strength of binders shall be determined as specified in EN 13454-2. 5.6 Shrinkage and swelling The values for shrinkage and swelling shall not exceed 0,2 mm/m. Shrinkage and swelling shall be determined as specified in EN 13454-2. 6 Requirements for factory made mixtures CA
6.1 General NOTE Factory made mixtures placed on the market of the European Economic Area, and therefore subject to conformity with the construction Products Directive, are covered by EN 13813; tests performed to EN 13454-2 may, however, be taken into account to demonstrate conformity to EN 13813. Factory made mixtures are, though, marked in accordance with EN 13813. 6.2 Reaction to fire Factory made mixtures (CA) are reaction to fire Class A1fl without testing according to Commission Decision 96/603/EC as amended, provided that they contain less than 1 % by mass or volume of organic material, whichever is the more onerous. Products which contain 1 % or more of organic material shall be tested and classified in ac-cordance with EN 13501-1. 6.3 Release of regulated substances NOTE For CE marking purposes see Annex ZA of EN 13813:2002. 6.4 Water vapour permeability Where the intended use of a factory made mixture is for moisture diffusion control, the permeability to water vapour of the factory made mixture shall be determined in accordance with EN 12086. 6.5 Impact sound insulation Impact sound insulation is a property of the assembled system and not of the product itself.

EN 13454-2. Where the consistency value is greater than 300 mm, it may be determined in accordance with
EN 12706. For premixed and prebatched mixtures the consistency is determined with a given water to solid ratio as specified by the supplier. 6.9.2 Flowing mixtures The spread shall be ≥ 220 mm. The spread shall be determined as specified in EN 13454-2. With this consistency the mixtures shall not segregate (no visual sedimentation, no visual development of layers). 6.9.3 Highly plastic mixtures The spread shall be between 150 mm and less than 220 mm and determined as specified in EN 13454-2. 6.9.4 Stiff mixtures The flow diameter shall be 110 mm to 140 mm. The flow diameter shall be determined as specified in EN 13454-2. 6.10 Working time The minimum working time for flowing, highly plastic and stiff mixtures shall be ≥ 30 min. The working time shall be determined as specified in EN 13454-2.

NOTE A description of the test is given in EN 13454-2. 6.12 Shrinkage and swelling A manufacturer of screed materials may declare the shrinkage value and swelling value of the screed material in mm/m, determined in accordance with EN 13454-2 or in accordance with EN 13872 where the product is intended to be applied at a thickness less than 10 mm. The values for shrinkage and swelling shall not exceed 0,2 mm/m.
