BM TRADA Certification has developed a heavyweight third-party Q-Mark Certification scheme for the lifetime performance of hinged and pivot doorsets. The scheme is based on Chiltern Dynamics’ highly successful Classification for Service Life Test Programme CDTM01.

The scheme allows manufacturers to demonstrate to specifiers that their products have passed this stringent CDTM01 testing regime and that through regular audits of the manufacturing process they can be assured of consistency as well as quality.
