Thickness and mass per unit area shall be determined in accordance with EN 1849-2, except that where the surface structure is caused by the inner layer, the mechanical thickness measurement method shall be applied and the result shall meet the requirements given in Table 2.
Terms and definitions of this European Standard shall have priority over those given in EN 1849-2. SIST EN 13956:2005

Table 2 — Thickness and mass per unit area requirements Effective thickness: Thickness of the sheet providing the waterproofing function including any surface texture but excluding any surface profile and backing shall be greater than 80 g/m2. The measured effective thickness shall lie within the declared tolerance of the MDV. The tolerance of the MDV shall lie within –5 % and +10 %. Single measurement: Each single measurement value shall lie within the declared tolerance of the MDV. The tolerance of the MDV shall lie within ±10 %. Mass: The mass per unit area shall lie within the declared tolerance of the MDV. The tolerance of the MDV shall lie within –5 % and +10 %.
5.2.3 Watertightness The watertightness shall be determined in accordance with EN 1928 using method B at an applied water pressure of 10 kPa (0,1 bar) and shall give a pass result. 5.2.4 Effects of liquid chemicals including water Information on the effect of liquid chemicals on plastics and rubber is given in Annex C. When further information on resistance to liquid chemicals is required, tests shall be conducted according to EN 1847 at a temperature of 23 °C for 28 days. 5.2.5 Fire performance 5.2.5.1 External fire performance Where the manufacturer wishes to declare external fire performance (e.g. when subject to regulatory requirements), the product shall be tested and classified in accordance with prEN 13501-5. Where the defined system meets the deemed to satisfy criteria1 no testing is required. 5.2.5.2 Reaction to fire Where required, the product shall be tested and classified in accordance with EN 13501-1:2002, Table 1. When tested according to EN ISO 11925-2, the products shall be tested under conditions of surface flame attack. 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 European Standard (the SBI test may be inappropriate for products covered by the European Standard). Pending results of such an investigation and discussions in the Fire Regulators Group, products covered by this European Standard are tested to EN ISO 11925-2. If and when a new fire test scenario and test method are developed for the products, this European Standard will be amended to refer to them.

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
