Scope

This standard specifies the positioning of safety guards in relation to the approach speed of human body parts. This standard specifies parameters based on the value of the approach speed of human body parts, and provides a method for determining the minimum distance from the detection zone or the actuating device of the safety guard to the danger zone. The approach speed values (gait speed and upper body movement) in this standard have been verified by timed tests or actual experience. This standard gives guidance for calculating minimum distances for typical approaches. This standard does not consider other forms of approach, such as running, jumping or falling. This standard specifies the distance from the detection area, detection surface, detection line, detection point or interlock guard entry point to the danger zone where the moving parts of the machine pose a hazard (such as crushing, shearing, entanglement). This standard applies to machinery defined in GB/T 15706. This standard does not apply to protection against risks due to hazards posed by projected solid or fluid materials, emissions, radiation or electricity. This standard does not apply to safety guards that can be moved closer to the danger zone than the calculated minimum distance without the use of tools (such as suspended two-hand controls). The minimum distances derived from this standard do not apply to safety guards that detect the presence of persons in areas already protected by guards or electro-sensitive protective equipment.
