benefits this has for the fenestration industry.
George said: “The force required to retract a locking mechanism can be affected by many factors including the quality of installation, alignment of keeps and door maintenance, temperature and building structure. As these factors fluctuate, so does the potential deviation of a door, necessitating meticulous testing against a stepped increase in tolerance to simulate real- world conditions.” “This imperative assessment aligns with PAS24, the robust security standard governing doorsets and windows, drawing its testing methodology from BS6375-2. Mandating a maximum force of 2Nm for retracting the locking mechanism, with lower force indicating smoother operation, underscores the commitment to fortified security and reliability.”
Testing against real world conditions Winkhaus wanted to measure the real-world impact that AV4 can have on a doors ease of use, and invited end-users to test how it operated under thermal expansion compared to other locks on the market. When it comes to thermal expansion, the industry standard tolerance for doors is up to 5mm with a tolerance of +or-2mm being commonplace. To simulate deviation, packers were inserted in 2mm increments with initial measurements being take from zero deviation. The doors used were from the same fabricator and were formed on the same date and batch of manufacture.
For the testing we benchmarked AV4 against
