The length and width shall be greater than or equal to the manufacturer's limiting value (MLV). The maximum deviation from straightness shall not exceed 20 mm per 10 m length, or in proportion for other lengths
(e.g. 10 mm per 5 m length). 5.4 Thickness and mass per unit area The thickness and mass per unit area shall be determined in accordance with EN 1849-1. Where a product is specified by mass per unit area no single measurement shall lie outside the declared tolerance of the manufacturer's declared value. Where a product is specified by thickness, no single measurement value shall lie outside the declared tolerance of the manufacturer's declared value. 5.5 Watertightness Watertightness shall be determined by Method A or B of EN 1928:2000 using a pressure of 2 kPa and shall give a pass result. 5.6 Resistance to impact Where required, the resistance to impact shall be determined in accordance with EN 12691 but with a drop height of 300 mm ± 5 mm. The smallest diameter it will resist shall be less than or equal to the manufacturer's
EN 13970:2004 (E) 7 limiting value. The expression of the manufacturer's limiting value in millimetres shall be accompanied by the drop height h = 300 mm. 5.7 Durability 5.7.1 After exposure to artificial ageing The product shall be exposed to elevated temperature of 70 °C for 12 weeks in accordance with EN 1296. The water vapour resistance of the aged product shall not change by more than ± 50 % of that of the un-aged product when tested to EN 1931. 5.7.2 Against chemicals Information about the chemical resistance of bitumen is given in Annex B. Where the product is likely to come into contact with a "not stable in all cases" substance the resistance shall be exposed according to EN 1847, the test parameters being declared with the result, and subsequently tested to EN 1931. The water vapour resistance shall not change by more than ± 50% of the manufacturer's declared value according to 5.11 and the result indicated as a pass. NOTE Experience has shown that water has little or no effect upon the in-service performance of reinforced bitumen sheets. 5.8 Flexibility at low temperatures (pliability) Where required, the flexibility at low temperatures shall be determined in accordance with EN 1109 and shall be less than or equal to the manufacturer's limiting value. NOTE This test does not give results corresponding to the application conditions in practice. Results should be used only to compare products of similar thickness and construction. 5.9 Resistance to tearing (nail shank) The tear resistance (nail shank) shall be determined in accordance with EN 12310-1 and shall lie within the declared tolerance of manufacturer's declared value. 5.10 Joint strength Where required, the joint strength shall be determined in accordance with EN 12317-1 and shall lie within the declared tolerance of manufacturer's declared value. 5.11 Water vapour transmission properties The water vapour resistance shall be determined in accordance with EN 1931 and shall lie within the declared tolerance of manufacturer's declared value. 5.12 Tensile properties The tensile properties shall be determined in accordance with EN 12311-1 and shall lie within the declared tolerance of manufacturer's declared value for the longitudinal and transverse directions of the sheet. 5.13 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.
EN 13970:2004 (E) 8 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 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.
5.14 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. Bitumen sheets 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. 6 Evaluation of conformity 6.1 General The compliance of a reinforced bitumen sheet with the requirements of this document and with the stated values (including classes) shall be demonstrated by: initial type testing; factory production control by the manufacturer. For the purposes of testing, products may be grouped into families, where it is considered that the selected property is common to all products within that family. 6.2 Type testing 6.2.1 General Initial type testing shall be performed to show conformity with this document. Tests previously performed in accordance with the provisions of this document (same product, same characteristic(s), test method, sampling procedure, system of attestation of conformity, etc.) may be taken into account. In addition, initial type testing shall be performed at the beginning of the production of a new product type (unless a member of the same family) or at the beginning of a new method of production (where this may affect the stated properties). All characteristics in Clause 5 shall be subject to initial type testing, where required. Whenever a change occurs in the product design, the raw material or supplier of the components, or the production process (subject to the definition of a family), which would change significantly one or more of the characteristics, the type tests shall be repeated for the appropriate characteristic(s). 6.2.2 Sampling Samples shall be taken according to EN 13416. The minimum number of tests to show compliance for initial and further type testing shall be one for all characteristics.
EN 13970:2004 (E) 9 6.3 Factory production control (FPC) 6.3.1 General The manufacturer shall establish, document and maintain an FPC system to ensure that the products placed on the market conform with the stated performance characteristics. The FPC system shall consist of procedures, regular inspections and tests and/or assessments and the use of the results to control raw and other incoming materials or components, equipment, the production process and the product. If a manufacturer claims compliance with FPC requirements by operating an EN ISO 9001 system,
EN ISO 9001 shall be applied in full and shall be made specific to the requirements of this document. The results of inspections, tests or assessments requiring action shall be recorded, as shall any action taken. The action to be taken when control values or criteria are not met shall be recorded. 6.3.2 Frequency of testing The characteristics to be controlled within the framework of factory production control are those for which the manufacturer claims a performance. Control of the product is required, either by direct testing or by indirect control. The frequency of testing shall be given in the manufacturer's FPC system.
