43 www.drivesncontrols.com March 2026 SAFETY AND SECURITY n Safety gate standard gets an update The ISO organisation has published a new edition of its ISO 14119 Safety of machinery - Interlocking devices associated with guards standard. The document sets out principles for the design and selection of safety gate systems. The requirements for accessible safety gates have now been specified. Design engineers are advised to familiarise themselves with the new requirements to guarantee that their machines are CE-compliant in the future. Since 2013, ISO 14119 has classified interlocking switches and regulated the specifications for installing guards. The new, third edition specifies the procedure for safeguarding accessible gates: if there is a risk that machinery will start up unexpectedly, devices such as a manual reset function or presence detection devices are required. There should also be suitable means for escape and emergency release. Specifically, the new edition requires the use of key transfer systems and the series connection of electromechanical contacts (the number of devices that can be connected in series) to increase the safety of accessible safety gates. These two subjects were previously described in ISO TR 19837 (interlocking systems) and ISO TR 24119 (series connections), and are now included in the new edition of ISO 14119, in Clause 6.3. “We recommend that you now use ISO 14119:2024 as a basis for designing safety gates, as it represents the current state-ofthe-art,” says Jan Franck, a member of the standards team at Pilz, ISO has updated its standard covering safety gate systems, which now requires the use of key transfer systems and the series connection of electromechanical contacts.
