DESCRIPTION

21/30405143 DC


This standard 21/30405143 DC BS EN ISO 14119. Safety of machinery. Interlocking devices associated with guards. Principles for design and selection is classified in these ICS categories:
  • 13.110 Safety of machinery

This International Standard specifies principles for the design and selection — independent of the nature of the energy source — of interlocking devices associated with guards and provides guidance of measures to minimize the possibility of defeat of interlocking devices in a reasonably foreseeable manner.

This International Standard covers the parts of guards which actuate interlocking devices and principles for the design, selection and application of trapped key interlocking devices and systems for machinery applications, independent of the type of energy used to control them or that they control

NOTE

ISO 14120 specifies general requirements for the design and construction of guards provided primarily to protect persons from mechanical hazards. The processing of the signal from the interlocking device to stop the machine and prevent unexpected start up is dealt with in ISO 13849-1 or IEC 62061:2015.
