Overview
EN 495-5:2013 - published by CEN - is the European test method for assessing foldability at low temperature of plastic and rubber flexible sheets for roof waterproofing. It defines the specimen preparation, apparatus, exposure and folding procedure, inspection and reporting needed to determine the lowest temperature at which a membrane can be folded without cracking. EN 495-5:2013 supersedes EN 495-5:2000 and adds allowance for instrumented folding apparatus and precision data from a Round Robin test.
Key topics and technical requirements
- Scope: Tests behaviour of plastic and rubber sheets for waterproofing to folding after low-temperature exposure (product characterization before use).
- Specimens:
- Standard: four specimens 100 × 50 mm (two longitudinal, two transverse) per temperature step.
- For artificially aged material, reduced specimens (two of 50 × 25 mm) may be used.
- Sheets with backing: sample from uncoated area; tested only in machine direction.
- Apparatus:
- Folding apparatus (metal or instrumented) with adjustable parallel plates.
- Cold chamber capable down to −45 °C with ±2 °C accuracy.
- Inspection tool: 6× magnifier.
- Procedure:
- Measure overall thickness (EN 1849-2) and set plate gap to three times thickness.
- Loop specimens (top surface inside/outside variants), condition 1 h at test temperature.
- Close folding apparatus within 1 s and hold for a minimum of 1 s in the cold chamber.
- Allow specimens to warm to (23 ± 5) °C and inspect folded area for cracks under 6× magnification.
- Repeat in 5 °C temperature steps; cold folding temperature = lowest step where no specimen shows cracking.
- Precision & reporting:
- Precision confirmed by a Round Robin (seven labs) with agreement at the 5 °C step size.
- Test report must reference EN 495-5, product identification, sampling (EN 13416), specimen prep, results, deviations and test date.

Diese Norm ist speziell für Kunststoff- und Gummiblätter zur Dachabdichtung ausgelegt und stellt sicher, dass diese Materialien auch unter extremen Bedingungen ihre Funktionalität bewahren. Die Norm beschreibt ein standardisiertes Verfahren zur Untersuchung des Verhaltens von Abdichtungsfolien bei tiefen Temperaturen. Dies ist entscheidend, da Abdichtungsfolien in unterschiedlichen klimatologischen Bedingungen eingesetzt werden und ihre Faltbarkeit bei Kälte direkt mit ihrer Langlebigkeit und Effektivität in realen Anwendungsszenarien verbunden ist. Durch die Festlegung klarer Testmethoden ermöglicht die SIST EN 495-5:2013 eine konsistente und nachvollziehbare Bewertung der Materialeigenschaften, die für Architekten, Bauingenieure und Materialhersteller von großer Bedeutung ist. Ein herausragendes Merkmal der Norm ist ihre Relevanz für die Qualitätssicherung von Dachabdichtungen. Die Faltbarkeit der Materialien wird als kritischer Parameter betrachtet, um sicherzustellen, dass das Dachsystem dauerhaft wasserdicht bleibt, selbst bei extremen klimatischen Bedingungen. Die Norm bietet somit eine wertvolle Grundlage für die Auswahl geeigneter Abdichtungsfolien und trägt zu einem höheren Standard in der Bauindustrie bei. Insgesamt stellt die SIST EN 495-5:2013 eine bedeutende Ressource für Fachleute im Bereich der Wasserdichtigkeit und Bauwesen dar. Ihre konsequente Anwendung kann dazu beitragen, kostspielige Schäden durch Wassereinbrüche zu vermeiden und die Lebensdauer von Dachsystemen erheblich zu verlängern. Die Norm schafft Vertrauen in die Qualität der verwendeten Materialien und stärkt die Position der europäischen Bauindustrie im globalen Wettbewerb.
