Overview - EN 13970:2004 (Bitumen water vapour control layers)

EN 13970:2004 is a CEN European product standard that defines flexible reinforced bitumen sheets intended for use as water vapour control layers (VCLs) in buildings. It sets out definitions, required product characteristics, test methods and the procedures for evaluation of conformity. The standard is a general product standard in the series for factory-made flexible sheets for waterproofing and was approved by CEN in 2004.

Key topics and technical requirements

• Scope and terms: Defines key terms (bitumen VCL, carrier/backing materials, MDV/MLV - manufacturer’s declared/limiting values).
• Product characteristics: Requirements and test methods for:
  • Visible defects (EN 1850-1) - product must be free of visible defects.
  • Dimensions and straightness (EN 1848-1) - length/width ≥ MLV; straightness ≤ 20 mm per 10 m.
  • Thickness and mass per unit area (EN 1849-1) - within declared tolerances.
  • Watertightness (EN 1928) - pass at 2 kPa pressure.
  • Resistance to impact (EN 12691) - evaluated with drop height h = 300 mm and compared to MLV.
  • Durability / ageing (EN 1296 then EN 1931) - artificial ageing at 70 °C for 12 weeks; water vapour resistance must not change by more than ±50%.
  • Chemical resistance (EN 1847 where relevant) - followed by EN 1931; water vapour resistance change ≤ ±50%.
  • Low temperature flexibility (EN 1109), tear resistance (EN 12310-1), joint strength (EN 12317-1), tensile properties (EN 12311-1), water vapour transmission (EN 1931).
  • Reaction to fire (EN 13501‑1 / EN ISO 11925‑2) when required.
• Dangerous substances: Sheets must not contain asbestos or coal tar; hazardous additives must be disclosed.
• Conformity assessment: Requires initial type testing and an ongoing Factory Production Control (FPC) system; sampling per EN 13416.

Practical applications and users

Who uses EN 13970:

• Manufacturers - to specify product design, testing and factory production control for bitumen VCLs.
• Test laboratories - to perform EN-referenced test methods and initial type testing.
• Architects and specifiers - to select compliant VCL products for roofs, walls and floors.
• Contractors and installers - to verify product marking, datasheets and on-site conformity.
• Regulatory bodies and certification agents - for assessing compliance with EU directives (see Annex ZA).

Typical applications:

• Use as vapour control layers within building envelopes to control moisture migration.
• Integration in roofs, walls and floor constructions where controlled water vapour resistance and durability are required.

(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

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 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.
