Overview
SIST EN 13970:2005 sets out the key definitions, characteristics, requirements, and conformity evaluation methods for flexible reinforced bitumen sheets used as water vapour control layers in buildings. Developed by the Slovenski inštitut za standardizacijo (SIST) and aligned with the European standard EN 13970:2004, this standard supports effective waterproofing and moisture control in construction. It is essential for manufacturers, specifiers, and construction professionals involved in selecting or verifying bitumen water vapour control products, helping ensure performance, safety, and compliance with EU regulations.
Key Topics
- Product Definitions: The standard defines key terms such as water vapour control, bitumen water vapour control layer, carrier materials, and reinforcement types (e.g., oxidized, elastomeric, or plastomeric bitumens).
- Product Characteristics: It specifies measurable properties such as watertightness, thickness, mass per unit area, visible defects, tensile properties, joint strength, flexibility at low temperatures, and resistance to tearing and impact.
- Test Methods: Clear references are provided to harmonized EN test methods for each characteristic (e.g., EN 1849-1 for thickness, EN 1928 for watertightness, EN 12311-1 for tensile properties, EN 1931 for water vapour transmission).
- Durability and Resistance: Requirements on artificial ageing, chemical resistance, and performance after exposure to potential in-service conditions ensure long-term reliability.
- Evaluation of Conformity: Guidance is given on type testing, factory production control, sampling procedures, frequency of testing, and criteria for compliance.
- Marking and Labelling: Instructions are included for CE marking, product labelling, and mandatory data to be provided on rolls and technical data sheets, contributing to traceability and regulatory compliance.
Applications
- Building Construction: These sheets are vital in roofs, walls, and floors for controlling the movement of water and water vapour, which helps to prevent condensation, mold growth, and structural damage.
- New Construction and Renovation: The standard’s requirements apply to both new buildings and refurbishment projects, enhancing building envelope performance.
- Product Specification and Procurement: Architects, engineers, and procurement teams use the standard to specify materials that meet regulatory and project requirements for waterproofing and water vapour control.
- Quality Control: Manufacturers employ the standard for initial type testing and to establish factory production control systems, ensuring consistent product quality for the marketplace.
- Regulatory Compliance: Products conforming to SIST EN 13970:2005 are prepared for CE marking and compliance with the EU Construction Products Regulation, aiding market access across Europe.

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 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.
