SIST EN 13859-1:2014

EN 13859-1:2014 (E) 9 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 web site on EUROPA accessed through: http://ec.europa.eu/enterprise/construction/cpd-ds/. 5 Testing 5.1 Sampling Samples shall be taken in accordance with EN 13416. 5.2 Test methods 5.2.1 Determination of dimensions, straightness and mass per unit area The length, width, straightness and mass per unit area of underlays shall be determined in accordance with EN 1848-1 and EN 1849-1 for bitumen sheets and in accordance with EN 1848-2 and EN 1849-2 for all other sheets. 5.2.2 Determination of reaction to fire Where required, the product shall be tested and classified in accordance with EN 13501-1:2007+A1:2009, Table 1. When tested according to EN ISO 11925-2, the products shall be tested under conditions of surface flame attack (surface exposure). NOTE It is currently considered that the Euroclasses Classification system at Classes D and above requires investigation to determine its appropriateness to the products covered by this document (the SBI test (EN 13823) may be inappropriate for products covered by the document). Pending results of such an investigation and discussions in the Fire Regulators Group, products covered by this document are tested to EN ISO 11925-2. If and when a new fire test scenario and test method are developed for the products, this document will be amended to refer to them. The underlays, where no limitation in the application is requested, shall be tested free hanging (without substrate) only. The classification obtained shall be applied to all unsupported and supported end use applications. If the intended use of the underlay is solely limited to being supported on a specific substrate, e. g. wood, mineral wool, polyurethane, it should be tested in the end use application in accordance with EN 13238. 5.2.3 Determination of resistance to water penetration Class W1 The resistance to water penetration Class W1 shall be determined in accordance with EN 1928:2000, Method A, with the modifications that: — water column shall be 200 mm; — using water dyed with 0,05 % eosin (instead of a moisture indicating mixture of sugar and methylene blue); — one layer of laboratory filter paper with a mass per unit area of 80 g/m2; — test period: 2 h (instead of 24 h); — three test specimens are used.

Other measuring methods shall also be allowed if the correlation with 5.2.5 is proved and recorded. If the water vapour diffusion-equivalent air layer thickness sd is above or equal to 0,2 m the product shall be tested in accordance with 5.2.5.1. If the sd value is below 0,2 m the product shall be tested in accordance with 5.2.5.2. If the sd value is below 0,1 m the standard deviation s shall also be recorded in the test report. 4.3.4 Tensile properties The product shall be tested in accordance with 5.2.6 and the results shall lie within the declared tolerance of the manufacturer's declared value for tensile strength and the maximum and/or minimum values for elongation for both longitudinal and transverse directions. 4.3.5

FprEN 13859-1:2013 (E) 9 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 web site on EUROPA accessed through: http://ec.europa.eu/enterprise/construction/cpd-ds/. 5 Testing 5.1 Sampling Samples shall be taken in accordance with EN 13416. 5.2 Test methods 5.2.1 Determination of dimensions, straightness and mass per unit area The length, width, straightness and mass per unit area of underlays shall be determined in accordance with EN 1848-1 and EN 1849-1 for bitumen sheets and in accordance with EN 1848-2 and EN 1849-2 for all other sheets. 5.2.2 Determination of reaction to fire Where required, the product shall be tested and classified in accordance with EN 13501-1:2007+A1:2009, Table 1. When tested according to EN ISO 11925-2, the products shall be tested under conditions of surface flame attack (surface exposure). NOTE It is currently considered that the Euroclasses Classification system at Classes D and above requires investigation to determine its appropriateness to the products covered by this document (the SBI test (EN 13823) may be inappropriate for products covered by the document). Pending results of such an investigation and discussions in the Fire Regulators Group, products covered by this document are tested to EN ISO 11925-2.

If and when a new fire test scenario and test method are developed for the products, this document will be amended to refer to them. The underlays, where no limitation in the application is requested, shall be tested free hanging (without substrate) only. The classification obtained shall be applied to all unsupported and supported end use applications. If the intended use of the underlay is solely limited to being supported on a specific substrate, e. g. wood, mineral wool, polyurethane, it should be tested in the end use application in accordance with EN 13238. 5.2.3 Determination of resistance to water penetration Class W1 The resistance to water penetration Class W1 shall be determined in accordance with EN 1928:2000, Method A, with the modifications that:  water column shall be 200 mm;  using water dyed with 0,05 % eosin (instead of a moisture indicating mixture of sugar and methylene blue);  one layer of laboratory filter paper with a mass per unit area of 80 g/m2;  test period: 2 h (instead of 24 h);  three test specimens are used. kSIST FprEN 13859-1:2013

The manufacturer shall always retain the overall control and shall have the necessary means to take responsibility for the product. NOTE The assignment of tasks to the notified bodies and the manufacturer is shown in Annex ZA, Table ZA.3. 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. NOTE Same AVCP system means testing by an independent third party, under the responsibility of a notified product certification body. For the purposes of assessment, the manufacturer's products may be grouped into families, where it is considered that the results for one or more characteristics from any one product within the family are representative for those same characteristics for all products within that same family

Products may be grouped in different families for different characteristics. Reference to the assessment method standards should be made to allow the selection of a suitable representative sample. In addition, the determination of the product type shall be performed for all characteristics included in the standard for which the manufacturer declares the performance (see Table D.1):  at the beginning of the production of a new or modified underlays for discontinuous roofing (unless a member of the same
