Window and Door Testing

Our testing facility for windows and doors is part of the accredited EPH laboratory.

The EPH issues proof of performance for product features of windows, doors and frame materials that are required by the provisions of the European product standard DIN EN 14351-1 for CE marking and also by EPH’s clients.

The EPH has decades of experience in testing CE performance parameters for usability, but also in evaluating burglary-resistant performance parameters, characteristic values relevant to heat insulation or ventilation in special window designs.

Thanks to our partnership with RAL Quality Associations/RAL-Gütegemeinschaften, we are able to offer special services as a testing, surveillance and certification body.
