Flexible sheets for waterproofing - Determination of resistance to ozone - Plastic and rubber sheets for roof waterproofing
This European Standard specifies a method for the determination of the resistance of plastic and rubber sheets for waterproofing to cracking when exposed, under static tensile strain, to air containing a definite concentration of ozone and at a definite temperature without the effects of direct light.

Diese Europäische Norm legt ein Verfahren zur Bestimmung des Widerstandes von Abdichtungsbahnen aus Kunststoffen und Elastomeren gegen Rissbildung fest, wenn sie unter statischer Zugbelastung der Luft mit festgelegter Ozonkonzentration und bei festgelegter Temperatur und ohne direkte Lichteinwirkung ausgesetzt werden.
Feuilles souples d'étanchéité - Détermination de la résistance à l'ozone - Feuilles d'étanchéité de toiture plastiques et élastomères
La présente Norme européenne spécifie une méthode de détermination de la résistance à l'apparition de craquelage sur les feuilles d’étanchéité de toiture plastiques et élastomères lorsque celles-ci sont exposées, sous contrainte de traction statique, à de l’air contenant une concentration donnée d’ozone, à une température donnée et à l’abri de la lumière directe.

Overview
EN 1844:2013 - produced by CEN - specifies a laboratory method to determine the resistance of plastic and rubber flexible sheets for roof waterproofing to ozone-induced cracking. The test evaluates whether waterproofing membranes develop cracks when exposed, under static tensile strain, to a controlled ozone atmosphere and temperature, with direct light excluded. EN 1844:2013 supersedes EN 1844:2001 and includes a technical correction to the ozone concentration used in testing.
Key topics and technical requirements
- Scope: Assessment of cracking of polymeric and elastomeric roofing sheets (as manufactured or supplied), not installed membrane systems.
- Sampling: Follow EN 13416 for representative sampling of sheets.
- Test specimens: Strips (≥10 mm wide; ≥40 mm length between grips); surface must be undamaged; at least three specimens per test.
- Conditioning
- Unstrained: minimum 16 h after manufacture before straining (with specified upper limits for some test types).
- Strained: 48–96 h in ozone‑free dark at (23 ± 2) °C after stretching.
- Test conditions
- Ozone concentration: (200 ± 20) pphm (note guidance on expressing ozone as partial pressure per ISO 1431‑1).
- Temperature: (40 ± 2) °C.
- Relative humidity: (65 ± 5) %.
- Exposure time: (168 ± 2) h (one week).
- Elongation: (20 ± 2) % static strain.
- Apparatus: In accordance with ISO 1431‑1; ozone chamber must allow control of relative humidity and temperature.
- Result reporting: Simple outcome - “no cracking” or “cracking”. Test report must reference EN 1844 and include specimen prep, number tested, air flow, whether cracking occurred, dates, and other test particulars.
- Precision: No precision data provided in this revision.
Practical applications and users
- Manufacturers of plastic and rubber roofing membranes use EN 1844:2013 to verify material resistance to ozone and to support product data sheets.
- Independent testing laboratories and quality control departments adopt the method for type testing and production checks.
- Roof system specifiers, architects, consultants and building owners rely on results to select materials for ozone-exposed installations (urban/industrial environments).
- Regulatory bodies and certification schemes can reference EN 1844 when setting durability or conformity requirements for roofing membranes.
