Tile Adhesives - EN 12004

Systems of assessment and verification of constancy of performance (AVCP) to be applied to tile adhesives are determined according to the table below in accordance with the definitions given in the EN 12004 standard.


Intended Uses

Level or Classes

AVCP system(s)

Adhesives for tiles

For internal and external uses in building and other civil engineering works



For uses subject to reaction fire regulations

(A1, A2, B, C)*


(A1, A2, B, C)**, D, E


(A1to E)*** and  F


* Products/materials for which a clearly identifiable stage in the production process results in an improvement of the reaction to fire classification (e.g. an addition of fire retardants or a limiting of organic materials)
** Products/materials not covered by footnote (*)
*** Products/materials that do not require to be tested for reaction to fire (e.g. products/ materials of Class A1 according to Commission Decision 96/603/EC).

The approval of conformity of tile adhesives specified in Table ZA.2 must be based on the evaluation of conformity procedures shown in Table ZA.3 containing the result of the application of the articles of this standard.


Content of the task

Tasks under the responsibility of the manufacturer

Factory product control (FPC)

Parameters related to essential characteristics of Table ZA.1.1 to ZA.1.4, which have to be declared fort he relevant intended uses

Tasks under the responsibility of the notified body

Initial type testing by a notified test laboratory

Essential characteristics of Tables ZA.1.1to ZA.1.4, which have to be declared for thr relevant intended uses

Tests Required to be Performed by Notified Laboratories: For initial type tests, the control activities of the certification body for products included in system 3 are limited to the following features. The producer is responsible for the application of other tests given in the ZA.1 table.

1) Reaction to fire,
2) Bond strength,
3) Durability of bond strength against climate/ heat ageing action,
4) Durability of bond strength against water/humidity action,
5) Durability of bond strength against freeze-thaw cycles
