SIST EN 13970:2005 is the Slovenian adoption of EN 13970:2004 from CEN. It covers flexible reinforced bitumen sheets intended to act as water vapour control layers in buildings, and it specifies the definitions, product characteristics, test methods and conformity evaluation used by manufacturers, test laboratories and specifiers.
What does SIST EN 13970:2005 specify?
SIST EN 13970:2005 specifies the requirements for flexible reinforced bitumen sheets used as water vapour control layers for buildings. It is organized into clauses on scope, normative references, terms and definitions, product characteristics, conformity assessment, product data sheets, and marking, labelling and packaging.

| Annex B | Example of a product data sheet |
| Annex ZA | Clauses addressing essential requirements and other provisions of EU Directives, including CE marking and attestation of conformity |
What are the key requirements of SIST EN 13970:2005?
SIST EN 13970:2005 ties product acceptance to named test methods and declared values. The main idea is simple: the manufacturer states the relevant performance, and the product is checked against those stated values or limits.
Product characteristics and test methods
Clause 5 requires the product to be free of visible defects, checked to EN 1850-1. Dimensions and straightness are verified to EN 1848-1, with length and width meeting the manufacturer’s limiting value (MLV) and straightness staying within the stated limit.
Thickness and mass per unit area are checked to EN 1849-1 against the manufacturer’s declared value (MDV). Watertightness is tested to EN 1928:2000 at 2 kPa and must pass. In practice, these requirements tell the buyer whether the sheet arrives in the right size, is uniform, and will hold back liquid water.
Mechanical and durability performance
Clause 5 also covers resistance to impact, tearing, joint strength, tensile properties and low temperature flexibility. Impact resistance uses EN 12691 with a 300 mm drop height, while tear resistance, joint strength and tensile properties use EN 12310-1, EN 12317-1 and EN 12311-1.
Durability is checked in two ways. After artificial ageing in EN 1296, water vapour resistance measured to EN 1931 must not change by more than ±50%. Where chemical exposure is relevant, EN 1847 is used before re-testing to EN 1931, again with a ±50% limit. For a reader, this means the document asks for evidence that the sheet still performs after ageing or contact with chemicals likely to matter in use.
Fire and substance requirements
Clause 5.13 requires reaction to fire testing and classification according to EN 13501-1:2002, with testing under surface flame attack to EN ISO 11925-2. Clause 5.14 also addresses dangerous substances, including asbestos and coal tar constituents, and requires hazardous additives or constituents to be disclosed.
Conformity evaluation and documentation
Clause 6 requires initial type testing and factory production control (FPC). Initial type testing covers the characteristics in Clause 5 as required, and samples are taken according to EN 13416. The FPC system must be documented and maintained, and its frequency is set by the manufacturer.
Clause 7 requires a technical data sheet with the product name, manufacturer, origin or traceable code, method of application, test results, certification mark if any, consumer information, and a description of the sheet. Clause 8 requires marking on each roll or consignment, including production identification, trade name, dimensions, thickness or mass, and any required dangerous-substance labelling.
What terms does SIST EN 13970:2005 define?
- Water vapour control - action that prevents or controls the passage of water vapour through a building element.
- Bitumen water vapour control layer - a flexible sheet of bitumen or a bitumen composite used to control movement of water and water vapour through a wall, floor or roof.
- Carrier material - material incorporated into or onto the sheet to provide stability and/or mechanical resistance.
- Backing material - material added to the sheet without a permanent mechanical function.
- Manufacturer's limiting value (MLV) - a value stated by the manufacturer that the test result must meet, either as a minimum or a maximum.
- Manufacturer's declared value (MDV) - a value declared by the manufacturer together with a declared tolerance.
- Reinforced bitumen sheet - a factory-made flexible bitumen sheet with one or more carriers, supplied in roll form.
- Sample / test piece / test specimen - the document distinguishes the piece taken from production, the part cut for testing, and the precise specimen used in the test.
Who uses SIST EN 13970:2005?
SIST EN 13970:2005 is used by manufacturers of flexible sheets for waterproofing, especially bitumen sheets intended for water vapour control layers. It is also used by test laboratories, notified bodies, quality and production control staff, and technical buyers who need a common basis for product claims, sampling, and conformity evidence. In practice, it supports product design, routine production control, technical documentation and CE-related information.
What changed in SIST EN 13970:2005 from the previous edition?
SIST EN 13970:2005 is identical to EN 13970:2004.
Which standards are used with SIST EN 13970:2005?
SIST EN 13970:2005 depends on several test and support standards, including EN 13416 for sampling; EN 1850-1 for visible defects; EN 1848-1 for dimensions and straightness; EN 1849-1 for thickness and mass; EN 1928 for watertightness; EN 1931 for water vapour transmission properties; EN 1296 for artificial ageing; EN 1847 for exposure to liquid chemicals; EN 1109, EN 12310-1, EN 12311-1, EN 12317-1 and EN 12691 for flexibility and mechanical properties; EN 13501-1 and EN ISO 11925-2 for reaction to fire; and EN ISO 9001 where a manufacturer uses that system as the basis for FPC.
What does the SIST EN 13970:2005 document contain?
SIST EN 13970:2005 contains the product definition, the list of key performance characteristics, and the test methods used to verify them. It also contains the conformity assessment logic, including initial type testing, family grouping, and factory production control. The annexes add practical material: chemical resistance information, an example data sheet, and the CE-marking route under EU provisions.

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.
