EN 13956:2005 (E) 10 5.2.6 Hail resistance Where required, the hail resistance of the sheet shall be determined in accordance with EN 13583 and shall be greater than or equal to the manufacturer's limiting value (MLV). 5.2.7 Joint strength Where required, the peel resistance of joints shall be determined in accordance with EN 12316-2. The peel resistance shall be greater than or equal to the manufacturer's limiting value (MLV). Where required, the shear resistance of joints shall be determined in accordance with EN 12317-2. The shear resistance shall be greater than or equal to the manufacturer's limiting value (MLV). If no result can be obtained due to too great an elongation, the grip distance may be reduced. 5.2.8 Water vapour properties If necessary, the moisture resistance factor µ of plastic and rubber sheets may be determined in accordance with EN 1931 and the result shall lie within the declared tolerance of the MDV. The tolerance of the MDV shall lie within ±30 %. 5.2.9 Tensile properties (strength and elongation) The tensile properties for homogenous sheets and sheets with a non-woven inner layer (e.g. fibre glass mat) of less than or equal to 80 g/m2 shall be determined in accordance with Method B of EN 12311-2. For all other sheets Method A of EN 12311-2 shall be used to determine tensile properties. The tensile force (Method A) or the tensile stress (Method B) shall be greater than or equal to the manufacturer's minimum limiting value (MLV) for the longitudinal and transverse direction of the sheet. The mean of the elongation at maximum tensile force (Method A) or the mean of the elongation at break (Method B) shall be greater than or equal to the manufacturer's limiting value (MLV) for the longitudinal and transverse direction of the sheet. 5.2.10 Resistance to impact Where required, the resistance to impact shall be determined in accordance with EN 12691 and shall be greater than or equal to the manufacturer's limiting value (MLV). 5.2.11 Resistance to static loading Where required, the resistance to static loading of the sheet shall be determined in accordance with either method A or method B of EN 12730 and shall be greater than or equal to the manufacturer's limiting value (MLV). If method A is used, the depth of the penetrating tool shall not exceed 10 mm. 5.2.12 Tear resistance Where required, the tear force shall be determined in accordance with EN 12310-2. The mean of the tear resistance (maximum tensile force of pre-cut test specimen) shall be greater than or equal to the manufacturer's limiting value (MLV) for the longitudinal and transverse direction of the sheet. 5.2.13 Resistance to root penetration The resistance to root penetration shall only be determined for products used as root barriers. Where required, the resistance to root penetration determined in accordance with prEN 13948 shall give a pass result. 5.2.14 Dimensional stability Dimensional stability shall be determined in accordance with EN 1107-2. The mean of the dimensional change in length (ûL) and width (ûT) shall be less than or equal to the manufacturer's limiting value (MLV). SIST EN 13956:2005
EN 13956:2005 (E) 11 5.2.15 Foldability at low temperature Foldability at low temperature shall be determined in accordance with EN 495-5. Only the top surface (the upper side of the sheet as used in-situ) shall be tested. The cold folding temperature shall be less than or equal to the manufacturer's limiting value (MLV). 5.2.16 Behaviour following exposure to UV radiation, elevated temperature and water Where required, when the product is subjected to exposure according to EN 1297, the duration of exposure to UV shall be 1 000 h. Following exposure, the change in visual aspects shall be determined according to EN 1297:2004, Annex B.
Surface cracks according to EN 1297:2004, Table B.1, Grades 0, 1 and 2 will give a pass result for the visual examination. Grade 3 will give a fail result. NOTE 1 The purpose of testing in accordance to EN 1297 is to characterize the long-term ageing behaviour of plastic and rubber sheets. The test does not give results corresponding to the service conditions in practice. Results should only be used to compare products of similar thickness, construction and composition, and they cannot be used for general durability classification. The chosen exposure duration for artificial ageing in accordance to EN 1297 has no relevance to a real product lifetime. NOTE 2 Sheets passing ETAG 006 requirements are considered to comply with the criteria for behaviour following exposure to UV radiation, elevated temperature and water. 5.2.17 Resistance to ozone Where required, the sheet shall be tested according to EN 1844 and the sheet shall show no cracks. This test is only required for sheets made of rubber materials. 5.2.18 Exposure to contact with bitumen Where required, the behaviour of the sheet where it may come in contact with bitumen shall be determined in accordance with prEN 1548. The sheet is compatible with bitumen if: a) for sheets with an inner layer or backing, the percentage loss in mass is less than or equal to 5 %; b) for sheets without an inner layer or backing, the change in Young's Modulus is less than or equal to 50 %. Results obtained by this test method from sheets without an inner layer or backing can be applied to sheets manufactured with same chemical formulation but having inner reinforcement layers or backing. The results obtained on a given thickness apply to any product of the same formulation with greater thickness.
By experience, sheets with a non-woven backing of at least 150 g/m2 or equivalent, which prevents any contact of the waterproofing membrane with bitumen, are considered as bitumen compatible. 5.3 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. NOTE See also [3] and [4]. SIST EN 13956:2005
