Greetings All. The IEC/EN 61010-1 table 12, Risk assessment of mechanical hazards to body parts, states that a hazard can be avoidable if the speed of the motion was reduced. Reduced to what speed? It says, "The motion is visible and velocity is low enough for body parts to be removed without being trapped".
This 2010 version of the standard is very helpful by including max forces and max continuous contact pressures, but does not specify a speed or velocity. I assume the information I am after can be found in some other standard so I have come to you for help. For instance, the ISO 16089:2015 says in some conditions a speed of 0.5 meter per minute is allowed (only 0.33 inches per second) or 2 meters per minute (1.3 inch per second) if you have a Hold-To-Run device. Are these values universal? Are there other standards that do a better job at specifying actual values to consider when evaluating mechanical hazards? Are there "Rules of Thumb" that field inspectors use to make this determination? Do the occupational health and safety organizations provide actual values to design and test to? Thanks to all.
