GB/T 18831-2017 Safety of machinery—Interlocking devices associated with guards—Principles for design and selection

Scope: This standard specifies the principles for the design and selection of interlocks associated with guards, regardless of the type of energy used. This standard applies to components of drive interlocks in guards. Note: The general requirements for the design and manufacture of guards specified in ISO 14120 are mainly used to prevent mechanical hazards. For the processing of the signal issued by the interlock device to stop the machine and keep it still, see GB/T 16855.1 or IEC 62061. This standard does not specify all specific requirements for key retention systems. This standard gives measures to prevent, as far as possible, the abandonment of interlocks in a reasonably foreseeable manner.
