Curtain walling - Watertightness - Laboratory test under static pressure
This standard defines the method for determining the watertightness of curtain walling, both its fixed and openable parts. It describes how the outside face of the specimen should be subjected to a continuous film of water with a positive static air pressure. NOTE: This standard applies to curtain walling in accordance with WI 00033238.
Vorhangfassaden - Schlagregendichtheit - Laborprüfung unter Aufbringung von statischem Druck
In dieser Norm wird das Verfahren zur Bestimmung der Schlagregendichtheit der feststehenden und öffenbaren Teile von Vorhangfassaden festgelegt. Es wird beschrieben, wie auf die Außenfläche des Prüfkörpers ein kontinuierlicher Wasserfilm bei positivem statischem Luftdruck aufgebracht werden sollte. ANMERKUNG: Diese Norm gilt für Vorhangfassaden nach WI 00033238.

Overview
EN 12155:2000 - issued by CEN and adopted as SIST EN 12155 - specifies a laboratory procedure for assessing the watertightness of curtain walling (both fixed and openable parts). The test subjects the external face of a curtain wall specimen to a continuous film of water while a positive static air pressure is applied, reproducing conditions that can drive water through joints and seals. This standard is intended for curtain walling manufactured in accordance with WI 00033238.
Key topics and requirements
- Scope and applicability: Applies to curtain wall systems (fixed and openable elements) where watertightness performance must be verified in a controlled laboratory environment.
- Test principle: The specimen’s outside face is exposed to a continuous water film combined with a positive static air pressure differential to evaluate leak paths under simulated rain/driving conditions.
- Specimen preparation: Requirements for mounting and sealing the test sample so results are repeatable and representative of installed systems.
- Test conditions and observation: Controlled application of water and air pressure, monitoring of interior face for water penetration, and documentation of leakage behaviour.
- Performance reporting: Structured recording of test set-up, conditions, observations and whether the specimen met the watertightness objectives defined for the test (note: specific acceptance criteria are defined within the standard).
Applications and who uses it
- Façade manufacturers use EN 12155 to validate product watertightness during development and production control.
- Independent test laboratories adopt the method to produce reproducible, comparable test reports for clients and regulators.
- Façade engineers and consultants reference this standard when specifying performance requirements and verifying compliance in tender documents.
- Architects and building owners rely on test results based on EN 12155 to select curtain wall systems suitable for local exposure conditions.
- Regulatory bodies and specifiers use results from this laboratory method as part of conformity assessment and quality assurance for building envelopes.
Related standards
- EN 12155 is part of the broader body of CEN standards covering curtain walling and façade performance. Related EN standards typically address air permeability, structural performance, and serviceability of façades (refer to CEN catalogue for specific references).
- Adopted national versions (e.g., SIST EN 12155:2001) reflect the same test method for local use.
Using EN 12155 helps ensure consistent, repeatable laboratory evaluation of curtain wall watertightness - a crucial step in delivering durable, weather-resistant façades.
