3.2 manufacturer's limiting value (MLV) value stated by the manufacturer to be met during testing. The manufacturer's limiting value can be a minimum or a maximum value according to statements made under product characteristics of this document 3.3 manufacturer's declared value (MDV) value declared by the manufacturer accompanied by a declared tolerance 3.4 sampling procedure used to select or constitute a sample 3.5 sample sheet from which a test piece is taken 3.6 test piece part of the sample from which test specimens are taken 3.7 test specimen piece of precise dimensions taken from the test piece SIST EN 13859-2:2005+A1:2009

4.3 Application related characteristics 4.3.1 Reaction to fire Where required, the reaction to fire shall be determined in accordance with 5.2.2. 4.3.2 Resistance to water penetration 4.3.2.1 Class W1 The product shall be classified as resistant to water penetration Class W1 if it passes the resistance to water penetration test in accordance with 5.2.3. If the product fails the test of resistance to water penetration indicated in 5.2.3, it shall be tested in accordance with 4.3.2.2. 4.3.2.2 Class W2 A product failing to pass the test indicated in 5.2.3 shall be tested in accordance with 5.2.4. If the measured mean volume of water passing through the specimens tested is less than 100 ml, the product shall be classified as resistant to water penetration Class W2. 4.3.2.3 Class W3 If the product fails the test indicated in 4.3.2.2, e.g. the measured mean volume passing the specimens exceeds 100 ml, it shall be classified as resistant to water penetration Class W3. SIST EN 13859-2:2005+A1:2009

4.3.3 Water vapour transmission properties The product shall be tested in accordance with 5.2.5 and the results shall lie within the declared tolerance of the manufacturer’s declared value. 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 Resistance to penetration of air The product shall be tested in accordance with 5.2.6. The test result shall be given as air permeability, expressed in m³ air per m², hour and 50 Pascals pressure difference (m³/(m² x h x 50 Pa)). The value of air permeability shall be equal to or lower than the manufacturer's limiting value. 4.3.5 Tensile properties The product shall be tested in accordance with 5.2.7 and the results shall lie within the declared tolerance of the manufacturer’s declared values for tensile strength and the maximum and/or minimum values for elongation for both longitudinal and transverse directions. 4.3.6 Resistance to tearing The resistance to tearing of underlays shall be tested in accordance with 5.2.8 and the results shall lie within the declared tolerance of the manufacturer's declared value in both (longitudinal and transverse) directions. 4.3.7 Dimensional stability The dimensional stability shall be determined in accordance with 5.2.9. 4.3.8 Flexibility at low temperature (pliability) Where appropriate, the flexibility at low temperature (pliability) determined in accordance with 5.2.10 shall be equal to or less than the manufacturer’s limiting value. 4.3.9 Artificial ageing behaviour The product shall be tested in accordance with 5.2.11. The mean values of tensile strength and elongation of the test specimens before and after artificial ageing shall be declared on the product data sheet by the manufacturer. The resistance to water penetration of artificially aged materials shall pass the same class declared by the manufacturer as defined in 4.3.2. For walls which do not exclude UV exposure, e.g. with open joints, the artificial ageing by UV shall be extended over a period of 5 000 h. NOTE "UV-exposed“ means that there are designed open joints in the wall covering which allow the penetration of daylight to reach the product. 4.4 Dangerous substances For products placed on the market within the European Economic Area see ZA.1. Outside the EEA products shall conform to any applicable provisions related to dangerous substances valid in the place of use. Underlays covered by this document shall not contain asbestos or coal tar constituents. The manufacturer shall disclose on the product wrapper and in the health and safety data sheets the use of any additive or constituent considered hazardous. SIST EN 13859-2:2005+A1:2009

If the intended use of the underlay is solely limited to being supported on a specific substrate, e. g. wood, mineral wool, polyurethane, it shall 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:  the 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. 5.2.4 Determination of resistance to water penetration Class W2 The resistance to water penetration Class W2 shall be determined in accordance with EN 13111 using three test specimens.
