摘要

Have you experienced any unintended consequences of a "temporary defeat" or bypassing guard interlocks? ISO 14119 "Safety of machinery-Interlocking devices associated with guards-Principles for design and selection" has just been updated and could help mitigate these issues.A Type B standard, ISO 14119: 2013 updates the previous 1998 edition and harmonizes EN 1088 into one international standard. This update expands original considerations to include additional technologies like RFID and electromagnetic guard locking. It also expands classifications for interlocking devices and provides additional requirements/specifications for installation. Extra care is provided for protection against manipulation of devices and guards in a reasonably foreseeable manner.
