EVS-EN ISO 14119:2025

ISO 14119 specifies principles for the design and selection (independent of the nature of the energy source) of interlocking devices associated with guards and guides measures to minimize the possibility of defeat of interlocking devices in a reasonably foreseeable manner.

ISO 14119 covers principles for the design, selection and application of the following:

— parts of the guards that actuate interlocking devices,
— trapped key interlocking devices and systems for machinery applications.

This standard is of relevance for the stakeholder groups representing the market players concerning machinery safety:

— machine manufacturers (small, medium and large enterprises),
— health and safety bodies (regulators, accident prevention organizations, market surveillance).
