This document is currently submitted to the CEN Enquiry.
This document will supersede EN 13454-1:2004.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports essential requirements of Regulation
(EU) No. 305/2011.
For relationship with Regulation (EU) No. 305/2011, see informative Annex ZA, which is an integral
part of this document.
Compared with the previous version the following changes have been made:
a) differentiation between binders for stiff and flowing mixtures;
b) modification of the strength classes for binders;
c) Clause 7 and Annex ZA updated in line with the CPR.
This document specifies binders and factory made mixtures where the principal active constituent is
calcium sulphate.
The requirements in EN 13454-1 on 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 sulphate are in
accordance with EN 13813.

6 Requirements for factory made mixtures
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 Regulation, are covered by EN 13813; tests performed to
prEN 13454-2 can, 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 A1 without testing according to Commission
fl
Decision 96/603/EC as amended, provided that they contain ≤ 1 % by mass or volume of organic
material, whichever is the more onerous. Products which contain > 1 % of organic material shall be
tested and classified in accordance with EN 13501-1.
6.3 Dangerous substances
Where required the release of dangerous substances shall be declared.
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.
8

---------------------- Page: 10 ----------------------
oSIST prEN 13454-1:2017
prEN 13454-1:2017 (E)
When relevant, the impact sound insulation of a system including factory made mixtures shall be
determined in accordance with the EN ISO 10140 series.
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 sulphate are not used as wearing surfaces and, consequently, they are
not ex-posed to chemical influences. A chemical resistance test is, therefore, not necessary.
6.8 pH-value
For factory made mixtures based on calcium sulphate the pH-value shall be ≥ 7 when determined in
accordance with prEN 13454-2.
NOTE The test is not necessary for factory made mixtures produced exclusively from binder as defined in 4.1
to 4.4 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 prEN 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
prEN 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 prEN 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 prEN 13454-2.
