Safety of machinery — Interlocking devices associated with guards — Principles for design and selection

ISO 14119:2013 specifies principles for the design and selection ? independent of the nature of the energy source ? of interlocking devices associated with guards.It covers the parts of guards which actuate interlocking devices. It does not necessarily provide all the specific requirements for trapped key systems.

ISO 14119:2013 provides measures to minimize defeat of interlocking devices in a reasonably foreseeable manner.
