Accessory fitting on all NBS crumpling devices to automate the pressuring process.
IGT Testing Systems has developed a device that can eliminate the variation in applied pressure. The NBS Automated Pressuring Device – ensures that the plunger is always pushed down with the same force. When the weight begins to rise it exerts a pressure of 100 N over a fixed period and so the danger of the crumpled ball being pushed too far is eliminated. The crumple test produces this way more reproducible test results. All versions of NBS crumple testers fit on the NBS Automated Pressuring Device which can therefore be ordered for use with all existing devices.
