3 Foreword This document (EN 16105:2011) has been prepared by Technical Committee CEN/TC 139 “Paints and varnishes”, the secretariat of which is held by DIN. 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of an identical text or by endorsement, at the latest by March 2012, and conflicting national standards shall be withdrawn at the latest by March 2012. 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. 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 and the United Kingdom.
5 1 Scope This European Standard specifies a laboratory method to determine the leaching behaviour of substances from coatings into water over defined time intervals. The release of substances from coatings under natural conditions cannot be determined with this method. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 23270, Paints and varnishes and their raw materials — Temperatures and humidities for conditioning and testing (ISO 3270:1984) EN ISO 15528, Paints, varnishes and raw materials for paints and varnishes — Sampling (ISO 15528:2000) 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 substance single chemical element or compound, or a complex structure of compounds, that is contained in the coating and can potentially be extracted from the coating via water contact 3.2 target substance substances to be tested according to 6.3.2 NOTE One or more target substances may be defined. For example, biocides can be the target substances (see Annex B). 3.3 biocide additive added to a coating material to prevent organisms responsible for microbiological degradation from attacking a coating material or a film thereof [EN ISO 4618:2006] NOTE A list of biocides is given in Annex I and IA of the Biocidal Products Directive 98/8/EC (Directive 98/8/EC of the European Parliament and of the Council of 16 February 1998 concerning the placing of biocidal products on the market – BPD). 3.4 coating continuous layer formed from a single or multiple application of a coating material to a substrate [EN ISO 4618:2006] SIST EN 16105:2011

7 4 Reagents 4.1 Standard leachant. Deionised water with a pH-value of (6 ± 1) and a water temperature of (23 ± 2) °C shall be used. 5 Apparatus 5.1 General Check the materials and equipment specified in 5.2.1 to 5.2.6 before use for proper operation and absence of interfering elements that might affect the results of the test. The equipment specified in 5.2.2 to 5.2.5 shall also be calibrated. 5.2 Equipment 5.2.1 Immersion container The container for immersion shall be made of a material inert to the target substances in the eluates (e.g. glass, PTFE coated). The immersion container shall be large enough to allow the test specimens to have the coated face completely exposed to water and contain 25 l water per square metre exposed face. The water column below (see Figure 1 a)) or above (see Figure 1 b)) the test surface shall be ≥ 10 mm. NOTE For example, a test specimen of 100 cm2 requires 250 ml water.
