EN 15824:2009 (E) 3 Foreword This document (EN 15824:2009) has been prepared by Technical Committee CEN/TC 125 “Masonry”, the secretariat of which is held by BSI. 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of an identical text or by endorsement, at the latest by January 2010, and conflicting national standards shall be withdrawn at the latest by January 2010. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. 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 EC Directive(s). For relationship with EC Directive(s), see informative Annex ZA, which is an integral part of this document. The CEN Enquiry on this Work Item was submitted as prEN 998-3:2006 but as a result of the discussion of the comments, the title of the draft was changed. As a result of this change the identifier of the Final Draft is changed too. 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, 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 and the United Kingdom.

EN 15824:2009 (E) 4 Introduction The properties of external renders and internal plasters based on organic binders are primarily determined by the type or types of binders used and their respective proportions. Organic renders and plasters can be defined according to the:
chemical and physical nature of the main active binder(s) and its state of dissolution, dispersion, or powder, which is decisive for the final characteristics of the surface covering with one or several coats; finishes determined by the aggregate distribution and application technique; properties and/or type of use. They are factory-made products produced in paste form, ready to use or in powder form. Renders and plasters do not attain their final characteristics until properly dried and hardened after application. The functions performed by renders and plasters depend on the properties of the type of raw materials used, on the thickness of the coats and the type of application. In addition, renders and plasters determine the final surface of the construction before eventually receiving a finish if required. The manufacturer designates the appropriate properties and characteristics for end use and appearance and should give information about the use of the renders or plasters and the relevant conditions of use.

NOTE For CE marking and labelling, clause ZA.3 applies. When Annex ZA.3 requires the CE marking to be accompanied by specific information from the list here above, relevant requirements can be considered to have been met. 7 Evaluation of conformity 7.1 General Conformity assessment is needed to demonstrate, by Initial Type Testing ITT (see 7.2), that the product complies with the requirements of this European Standard and that the performance declarations represent the true behaviour of the product and by Factory Production Control FPC (see 7.3) , that the performance declarations based on initial type testing results remain valid for subsequent products. The manufacturer or his agent shall demonstrate the compliance for his product with the requirements of this European standard by carrying out both ITT and FPC and is responsible for the product being in compliance with all the provisions. 7.2 Initial Type Tests (ITT) After completion of the development of a new product type and before the commencement of the manufacture and the offering for sale, appropriate initial type testing shall be carried out that the properties predicted during the development meet the requirements of this standard and the values to be declared for the product. For the verification of product characteristics requiring expensive and complicated special testing which is needed to be performed only during ITT, an individual manufacturer may use the ITT results obtained by someone else (another manufacturer) or carried out by industry to justify his own declaration of conformity regarding a product that he considers to be the same, provided that permission is given, and the test is valid for both products. Where a manufacturer produces the same product on more than one production line or unit, or in more than one factory, there may be no need to repeat ITT for these different production lines or units (the manufacturer takes responsibility for ensuring that the products are indeed the same). 7.2.1 Sampling Sampling shall be carried out in accordance with EN ISO 15528 for renders and plasters in paste form, or EN 1015-2 for renders and plasters in powder form.

NOTE Information about special properties may be included when it is intended to use the render or plaster in specific conditions. 6 Marking and labelling The designation (see 5.2) and abbreviation identifying the product shall be marked on the packaging, delivery ticket and/or the manufacturer’s data sheet or other information accompanying the product. NOTE For CE marking and labelling, clause ZA.3 applies. When Annex ZA.3 requires the CE marking to be accompanied by specific information from the list here above, relevant requirements can be considered to have been met. 7 Evaluation of conformity 7.1 General Conformity assessment is needed to demonstrate, by Initial Type Testing ITT (see 7.2), that the product complies with the requirements of this European Standard and that the performance declarations represent the true behaviour of the product and by Factory Production Control FPC (see 7.3) , that the performance declarations based on initial type testing results remain valid for subsequent products. The manufacturer (or his agent) shall demonstrate the compliance for his product with the requirements of this European standard by carrying out both ITT and FPC and is responsible for the product being in compliance with all the provisions. 7.2 Initial Type Tests (ITT) After completion of the development of a new product type and before the commencement of the manufacture and the offering for sale, appropriate initial type testing shall be carried out that the properties predicted during the development meet the requirements of this standard and the values to be declared for the product. For the verification of product characteristics requiring expensive and complicated special testing which is needed to be performed only during ITT, an individual manufacturer may use the ITT results obtained by someone else (another manufacturer) or carried out by industry to justify his own declaration of conformity regarding a product that he considers to be the same, provided that permission is given, and the test is valid for both products. Where a manufacturer produces the same product on more than one production line or unit, or in more than one factory, there may be no need to repeat ITT for these different production lines or units (the manufacturer takes responsibility for ensuring that the products are indeed the same). 7.2.1 Sampling Sampling shall be carried out in accordance with EN ISO 15528 for renders and plasters in paste form, or EN 1015-2 for renders and plasters in powder form. kSIST prEN 15824:2008
prEN 15824:2008 (E) 11 7.2.2 Reference test The tests to be conducted shall be reference tests as described in this standard for properly dried and hardened product properties according to paragraph 5, consistent with the product type’s intended use. 7.2.3 Repeating of initial type test
Initial type test shall also be carried out on existing products when a change in the basic materials or manufacturing procedures leads to the manufacturers consider to be a change in the product designation or the use of the product. In these cases the appropriate initial type tests carried out are those for the properties which are affected or need confirming and any new properties introduced by a change of use. 7.2.4 Recording The results of the initial type tests shall be recorded. 7.2.5 Application of test methods
As defined in the relevant clauses defining the requirements, tests could not be performed when the declaration of characteristics is based on tabulated values.
NOTE For CE marking, where some characteristics are not subject to regulations, it might be possible using the NPD option (see Annex ZA). 7.3 Factory Production Control (FPC) 7.3.1 General The manufacturer shall establish, document and maintain a FPC-system to enable continuing conformity with the standard and the declared values of the product placed on the market. The FPC-system shall consist of procedures for process control (incoming raw material and production process), finished products (tests on finished products and test equipment), and traceability treatment of
non-conforming products. Any FPC system complying with EN ISO 9001, and made specific to the requirements of this standard, is deemed to satisfy the requirement of FPC. 7.3.2 Process control 7.3.2.1 Incoming raw materials The manufacture shall define the acceptance criteria of raw materials, and the procedures operated to ensure that these are met; 7.3.2.2 Production process The relevant features of the production processes shall be defined giving the frequency of the manufacturer’s inspection checks, together with the required criteria and the required in-progress product characteristics. Actions to be taken when the criteria or the product characteristics are not achieved shall be specified by the manufacturer within the FPC documentation. All production equipment that has an influence on the declared values shall be controlled and regularly inspected according to the documented procedures, frequencies and criteria. kSIST prEN 15824:2008
prEN 15824:2008 (E) 12 7.3.3 Finished product conformity 7.3.3.1 Tests on the finished product The FPC system shall incorporate a sampling plan containing the frequencies of testing of the products. The results of testing shall be recorded. For production evaluation the manufacturer shall define the conformity criteria in the FPC documentation. Alternative methods of test, to the reference methods specified in this European Standard may be adopted except for initial type tests and in case of dispute, provided that these alternative methods satisfy the following: a) a correlation can be demonstrated between the results from the reference test and those from the alternative test and b) the information is available on which the correlation is based on. The sampling shall be representative for the production. The results of testing shall meet the specified compliance criteria and shall be recorded. 7.3.3.2 Test equipment All weighing, measuring and testing equipment which has an influence on the declared values shall be calibrated and regularly inspected in accordance with the documented procedures and frequencies, as stated in the FPC manual. 7.3.4 Statistical techniques Where and when possible and applicable, the results of inspections and testing shall be interpreted by means of statistical techniques, by attributes or by variables, to verify the product characteristics and to determine if the production conforms to the compliance criteria and the product conforms to the declared values. 7.3.5 Traceability – marking and stock control of products The marking and stock control shall be documented. Products shall be identifiable and traceable with regard to their production origin. 7.3.6 Non conforming products The procedure for dealing with non conforming products shall be documented. Products that do not conform to the requirements shall be segregated and marked accordingly. However, these may be reclassified by the manufacturer and given different declared values. The manufacturer shall take action to avoid a recurrence of the non conformity. kSIST prEN 15824:2008
