I'm trying to determine if a moving part is hazardous or not. According to IEC/EN 61010-1 section 7.3.4,
Forces less than those listed below are considered Non-Hazardous: * Contact pressure of 50 N/cm² with a maximum force of 150 N. * For body contact areas greater than 3 cm² a temporary force of 250 N is allowed for no more than 0.75 seconds. To determine "Contact pressure" I must take the Max Force (which I can measure) and divide it by the "Body Contact Area" in cm². But how do I know what my body contact area is for a finger tip, entire finger, or a hand? Are there standard values that are used in industry for these calculations? Are there values used for arm, head, foot, etc.? How about if the moving part creates a Sheer hazard? How is the Body Contact Area determined in this case? Thanks for any advice on this topic.
