The cyclic operation machine tests the operation and use of each multi point lock. The machine works by fitting the multi point lock in to a door, and then adding a handle and cylinder. The machine will then cycle test the lock by turning the cylinder to unlock; pull the handle down to open the door; close the door; lift the handle to engage the multi point hooks, and then finally lock the cylinder. This gives a true test of how the multi point lock will work in a real life situation.
Each multi point lock is cycle tested to 200,000 cycles.
Salt Spray Test
This machine tests the corrosion resistance of the multi point locks. The salt spray cabinet produces a corrosive environment, by releasing a dense saline fog into the chamber which the multi point locks are exposed to. This creates an accelerated corrosion of the MPL and allows us to test how well the locks would stand up in harsher environments.
The multi point locks are tested to BS EN1670 grade 4 for 420 hours.
