General Information
Overview
EN 12154:1999 - Curtain walling - Watertightness - Performance requirements and classification is a CEN standard that defines how the watertightness performance of curtain walling is specified and classified. It covers both fixed and openable parts of curtain façades when subjected to positive static air pressure. The standard was adopted by Slovenia as SIST EN 12154:2001.
Key topics and technical requirements
- Scope and applicability: Applies to curtain walling systems in accordance with WI 00033238, covering components and assemblies used in external façades.
- Watertightness performance: Establishes performance requirements and a classification system for resistance to water penetration under defined positive static air pressure conditions.
- Fixed vs openable parts: Differentiates requirements for non‑operable (fixed) elements and operable elements (e.g., vents, windows integrated in the curtain wall).
- Classification framework: Provides a structured approach to rank systems by watertightness performance (classification bands or levels), enabling comparison between products.
- Testing conditions: Specifies the use of controlled positive static air pressure during assessment (note: refer to the standard text for detailed test setups and thresholds).
- Documentation and conformity: Requires manufacturers and test laboratories to document results and classification to support specification and compliance.
Practical applications
- Façade design and specification: Architects and façade engineers use EN 12154 to specify minimum watertightness requirements for curtain wall systems in projects.
- Product selection and procurement: Clients and specifiers reference the classification to compare curtain wall products for performance and suitability.
- Factory and site quality control: Manufacturers use the standard to design products and verify production quality; installers use it to confirm installed performance.
- Testing and certification: Accredited test laboratories apply the standard’s criteria when issuing watertightness test reports and classification certificates.
- Regulatory and compliance checks: Building inspectors and compliance officers consult the classification to assess conformity with performance requirements.
Who uses this standard
- Façade and structural engineers
- Architects and building designers
- Curtain wall manufacturers and component suppliers
- Test laboratories and certification bodies
- Building owners, contractors, and specifiers
- Regulatory authorities and compliance consultants
