Auto Minimum Robustness of oculars test
LEMA TRM Auto Minimum Robustness
- AS/NZS 1067.1
Safety Eyewear Standards:
TRM device is used for testing static deformation, by applying a 100N mass on the lens sample.
The test can be executed manually or automatically.
Speed is controlled by means of an electronic inverter, with +/-3% precision.
The device comes with 5 pre-set descent speeds, but it is also possible to set different ones.
Deformation test time is set by means of a timer.
Sample deformation is measured in hundreds of millimeters and displayed on a digital indicator
BUILT FOLLOWING ISO 12311:2013 STANDARD.
