Window and Door Testing & Certification for the Construction and Building Industry

One-Stop-Shop Service from the Experts in Windows and Doors

These days, windows and doors aren't just windows and doors anymore. They are safety barriers, they can help prevent climate change, protect us against environmental incidents and come with state-of-the-art technology built in for our comfort, security, safety and insulation. However, with greater demands also come greater responsibilities to ensure that windows and doors can indeed fulfil the new functions they promise. TÜV Rheinland as the notified body can support you in fulfilling these standards and keeping the product’s promises.

We are accredited and notified to verify your windows and doors products (incl. any intended application of these products in building and construction) against their compliance with the CPD/CPR (European Construction Products Directive / European Construction Products Regulation) standards as stated in the 1999/93/EC Windows & Doors mandate for CE marking. The certifications we offer covers testing and certification of all types of external doors and windows to ensure burglar and bullet-proof safety, security, and environmental / climate / insulation efficiency. The fundament for certification is the EN 14351-1 and prEN16034 standard for windows and doors.

The CE Marking EN14351-1 Standard

The CE marking EN14351-1 standard applies to windows and doors and outlines norms that define product standards and performance characteristics.

Part 1 regulates windows and external pedestrian doorsets without resistance to fire and/or smoke leakage characteristics. This European Standard identifies material-independent performance characteristics under CE marking that are applicable to windows (including roof windows, roof windows with external fire resistance and French windows), external pedestrian doorsets (including unframed glass doorsets and escape route doorsets) and screens.

The EN14351-1 standard applies to:

  • Manually or power operated windows
  • Roof windows
  • French windows and screens
  • External pedestrian doorsets with flush or panelled leaves

The following related hardware is also covered in the standard:

  • Weather stripping
  • Glazed apertures when so intended
  • Windows with or without incorporated shutters and/or shutter boxes and/or blinds
  • Fully or partially glazed windows, including any non-transparent infill
  • Fixed or partly fixed windows or openable with one or more casements/sashes (e.g. hinged, projecting, pivoted, sliding etc)
  • Manually or power-operated windows
  • Integral fanlights

The products covered by this European Standard are not assessed for structural applications. It also does not apply to windows and pedestrian doorsets subject to regulations on smoke leakage and resistance to fire according to prEN 16034. However, individual characteristics and performance requirements are also relevant for these doors and windows.
