This document supersedes !EN 12004:2007". The start and finish of text introduced or altered by amendment is indicated in the text by tags ! ". 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 EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

EN 12004:2007+A1:2012 (E) 4 Introduction It is essential that the characteristics of the construction products defined in this standard consider that the normal stresses due to the works for which they are intended, assembled or installed, can be properly accommodated. Some special characteristics will take into account the type of substrate and that the adhesives should resist the degrading actions of climate, etc. Many properties of adhesives for tiling are mainly determined by the type of binders used. Different types of tile adhesives are defined according to the chemical nature of their binders. The different types have specific characteristics in terms of their application properties and final performance. The relationship between characteristics and the working conditions (dry or humid conditions, hot climate, fast setting, etc.) is not given in this standard. The manufacturer should give information about the use of the product and the correct conditions of use. The specifier should evaluate the state of the job site (mechanical and thermal influences) and choose the appropriate product considering all the possible risks. SIST EN 12004:2007+A1:2012

Tests which have previously been performed in accordance with the provisions of this standard (same product, same characteristic, test method, sampling procedure, etc.) may be taken into account for the purpose of demonstrating satisfactory initial type testing. Initial type tests shall also be carried out on existing products after any change in raw materials or manufacturing procedures that can modify the declared values of the characteristics or application properties. In these cases the appropriate initial type testing to be carried out are those for the characteristics and properties that can be affected and need confirmation; any new property or properties arising from a change of formulation or manufacturing procedure shall be tested and the results reported. The initial type testing shall be performed as listed in !Table 5". !Only one ITT is required where different manufacturing units are producing the same product, for the same manufacturer, using the same materials (having the same performance) and documented production and process control. Where components (e.g. cement) are used whose characteristics have already been determined by the component supplier on the basis of conformity with other product standards, these characteristics need not be re-assessed to demonstrate compliance with the European Standard. Retesting due to a new method of production or product modification, or change of supplier of components, shall only be performed if one or more of the stated performance characteristics will be downgraded, i.e. the mix design becomes dissimilar. A manufacturer may, however, always retest if he wishes to declare improved performance." SIST EN 12004:2007+A1:2012

They shall be kept for at least 10 years after the date of last manufacture of the products to which they relate. 5.4 Factory Production Control 5.4.1 General A Factory Production Control (FPC) plan shall be established and documented in a manual. Any change in raw materials, manufacturing procedures or control plan that can affect the properties of the product shall be recorded. The manual shall include the FPC procedures relevant to the declared properties, as confirmed by the initial tests. The FPC procedures shall consist of a system for the production quality control to ensure that the product conforms with this standard. The production control shall consist of the following main phases: 1) inspection and testing of raw materials, 2) inspection and testing of production equipment and process, 3) inspection and testing on finished products. 5.4.2 Production 5.4.2.1 Raw materials The manufacturer shall define the acceptance criteria and control procedures for incoming materials to ensure that these are not used until it has been verified that they conform to the required specifications. 5.4.2.2 Production process The manufacturer shall identify and define the plant and production processes and ensure that the processes are carrie
