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:
EN 13454-1:2004 (E) 7 a) prebatched (dry) in a factory and mixed on the construction site in factory specified proportions and conditions, b) premixed (dry) in a factory and mixed on the construction site by adding water, c) ready mixed (wet) which is supplied to the construction site in a pre-mixed and gauged condition. 5 Requirements for binders (CAB; CAC) 5.1 General 5.1.1 Reaction to fire Calcium sulfate binders (CAB and CAC) are reaction to fire Class A1fl without testing according to Commission De-cision 96/603/EC as amended, provided that they contain less than 1 % by mass or volume of organic material, whichever is the more onerous. For products which contain 1 % or more of organic material, the product shall be tested and classified in accordance with EN 13501-1. 5.1.2 Release of regulated substances NOTE For CE marking purposes see Annex ZA. 5.2 Content of calcium sulfate (CaSO4) The content of calcium sulfate in the following materials shall be: a) calcium sulfate binders (CAB): ≥ 85 % calcium sulfate by mass, b) calcium sulphate composite binders (CAC): ≥ 50 % and < 85 % calcium sulfate by mass.

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 13454-1:2004 (E) 9 When relevant, the impact sound insulation of a system including factory made mixtures shall be determined in ac-cordance with EN ISO 140-6. 6.6 Thermal resistance This requirement is defined in EN 13813. 6.7 Chemical resistance This requirement is defined in EN 13813. NOTE Floor screeds based on calcium sulfate are not used as wearing surfaces and, consequently, they are not exposed to chemical influences. A chemical resistance test is, therefore, not necessary. 6.8 pH For factory made mixtures based on calcium sulfate the pH value shall be ≥ 7 when determined in accordance with EN 13454-2. NOTE The test is not necessary for factory made mixtures produced exclusively from calcium sulfate binder (CAB) or cal-cium sulfate composite binder (CAC) as defined in 4.1 or 4.2 and aggregates as defined in 3.4 and controlled as specified in 4.3. 6.9 Consistency 6.9.1 General A manufacturer of screed materials may declare the consistency in mm determined in accordance with
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.
EN 13454-1:2004 (E) 10 The working time for ready mixed products begins when the product is loaded (including water). NOTE In EN 13813 the term "setting time" is used for "working time". 6.11 Strength 6.11.1 Compressive strength The compressive strength of factory made mixtures (CA) shall be designated by a "C" (for Compression) followed by the compressive strength class in N/mm2, given in Table 2 in accordance with EN 13813.

The flexural strength shall be determined as specified in EN 13892-2. 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.
EN 13454-1:2004 (E) 11 NOTE This requirement is not applicable for factory made mixtures (CA) produced exclusively from calcium sulfate binder (CAB) or calcium sulfate composite binder (CAC) as defined in 4.1 or 4.2 and aggregates as defined in 3.4 and controlled as specified in 4.3. 6.13 Other characteristics For other characteristics (i.e. surface hardness, resistance to rolling wheel, water permeability, bond strength, sound absorption, modulus of elasticity in flexure and electrical resistance) see EN 13813. 7 Evaluation of conformity 7.1 General Evaluation of conformity is carried out declaring conformity of binders (CAB), composite binders (CAC) and factory made mixtures (CA) with the requirements of this document on the basis of: a) initial type testing, b) factory production control. The purpose of the factory production control is to ensure that binders, composite binders and factory made mix-tures placed on the market conform to their technical specifications defined in Clauses 5 and 6. 7.2 Initial type testing Initial type testing shall be performed to show conformity with this document. Tests previously performed in accor-dance with the provisions of this document (same product, same characteristic(s), test method, sampling proce-dure, system of attestation of conformity etc.) may be taken into account. In addition, initial type testing shall be performed at the beginning of the production of a new product type or at the beginning of a new method of produc-tion (where this may affect the stated properties). The technical specifications and properties specified in this document are defined in terms of EN reference meth-ods which shall be used in the initial type testing to show conformity of the product to the document. 7.3 Factory production control Factory production control means the permanent internal control of production exercised by the manufacturer or his agent on the responsibility of the manufacturer himself. The conformity criteria given in EN 13813 apply. A control system in accordance with Table 4 will meet the control requirements subject to the product meeting the perform-ance requirements listed in Table 4. The manufacturer shall record the results of production control (manufacturer's record). These records shall include at least the following: identification of the product tested, date of sampling, test methods, test and inspection results, date of tests, identification of the responsible authority within the manufacturer, calibration records.
