Lepila in malte za ploščice - 1. del: Zahteve, ocenjevanje in preverjanje nespremenljivosti lastnosti, razvrščanje in označevanje

Ta evropski standard se uporablja za cementna lepila za keramične ploščice, disperzijska lepila in reakcijska lepila na osnovi smole za lepljenje ploščic na stene ali tla v zaprtih prostorih ali na prostem. Ta standard navaja izrazoslovje glede izdelkov, metod dela, lastnosti nanosa itd. za lepila za keramične ploščice. Ta evropski standard določa vrednosti glede učinkovitosti lepil za keramične ploščice (cementna lepila, disperzijska lepila in lepila na osnovi smole). Ta evropski standard ne zajema meril ali priporočil za projektiranje in nameščanje keramičnih ploščic. OPOMBA:    Lepila za keramične ploščice se lahko uporabljajo tudi za druge vrste ploščic (iz naravnega in aglomeriranega kamna itd.), če ne vplivajo škodljivo na te materiale.

EN 12004-1:2017 (E) 4 European foreword This document (EN 12004-1:2017) has been prepared by Technical Committee CEN/TC 67 “Ceramic tiles”, the secretariat of which is held by UNI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by August 2017, and conflicting national standards shall be withdrawn at the latest by November 2018. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 12004:2007+A1:2012. 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 construction works of Regulation No. 305/2011. For relationship with this Regulation, see informative Annex ZA, which is an integral part of this document. The significant technical changes between this European Standard and the previous edition are listed herewith: — Clause 3.6.1 replacement of the term “Fundamental” with “Basic”; — Clause 4, Tables 1, 2 and 3; — New Clause 5; — New Clause 6 in accordance with CEN guidance documents; — New Annex ZA (informative) in accordance with the CPR (Regulation (EU) No. 305/2011) and the Commission Delegated Regulations (EU) No. 157/2014 relative to DoP made available on websites, (EU) No. 574/2014 relative to the Model of DoP and (EU) No. 568/2014 relative to the assessment and verification of constancy of performance. 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, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. SIST EN 12004-1:2017



EN 12004-1:2017 (E) 5 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 of adhesives for ceramic tiles 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 12004-1:2017



EN 12004-1:2017 (E) 6 1 Scope This European Standard is applicable to the following three types of adhesives for ceramic tiles, i.e. cementitious ones for internal and external tile installations, dispersion and reaction resin ones for internal tile installations, on walls and floors. This European Standard gives the terminology concerning the products, working methods, application properties, etc, for ceramic tile adhesives. This European Standard specifies the performance requirements for the adhesives for ceramic tiles. It also specifies the appurtenant test methods, assessment and verification of constancy of performance (AVCP), as well as classification, designation and marking of adhesives for ceramic tiles. This European Standard does not provide criteria or recommendations for the design and installation of ceramic tiles. Ceramic tile adhesives may also be used for other types of tiles (natural and agglomerated stones, etc.), if they do not adversely affect these materials. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

The test media shall consist of the media to which the chemical resistant materials are to be exposed in service and the test conditions temperature, concentration, etc.) shall simulate the anticipated service and exposure conditions as closely as possible. 4.6 Release of dangerous substances Materials used in products shall not release any dangerous substances in excess of the maximum permitted levels specified in a relevant European Standard for the material or permitted in the national regulations of the member state of destination. National regulations on dangerous substances may require verification and declaration on release, and sometimes content, when construction products covered by this standard are placed on those markets. In the absence of European harmonized test methods, verification and declaration on release/content should be done taking into account national provisions in the place of use. NOTE An informative database covering European and national provisions on dangerous substances is available at the Construction website on EUROPA accessed through: http://ec.europa.eu/growth/tools-databases/cp-ds/ 5 Testing, assessment and sampling methods Testing and assessment methods and requirements for sampling shall be as set out in Clause 4 of this document. 6 Assessment and verification of constancy of performance (AVCP) 6.1 General The compliance of the adhesives for ceramic tiles with the requirements of this standard and with the performances declared by the manufacturer in the DoP shall be demonstrated by: — determination of the product-type on the base of type testing; — factory production control by the manufacturer, including product assessment. The manufacturer shall always retain the overall control and shall have the necessary means to take responsibility for the conformity of the product with its declared performances. 6.2 Type testing 6.2.1 General All performances related to characteristics included in this standard shall be determined when the manufacturer intends to declare the respective performances unless the standard gives provisions for declaring them without performing tests (e.g. use of previously existing data, CWFT and conventionally accepted performance). Assessment previously performed in accordance with the provisions of this standard, may be taken into account provided that they were made to the same or a more rigorous test method, under the same AVCP system on the same product or products of similar design, construction and functionality, such that the results are applicable to the product in question.
