Main Changes in the ISO 14119 Standard for Interlocking Devices

POSTED 06/19/2025

The updated ISO 14119:2024 typical – protecting interlocking gadgets linked with guards – used to be published perfect a pair of months within the past, replacing the 2013 version. This revision is necessary for machine builders, cease customers, and security professionals.

The adjustments had been also discussed in a most up-to-date webinar hosted by Fortress Security – scrutinize the recording here if you occur to missed it.

The same outdated covers the guidelines for the manufacture and various of interlocking gadgets linked with guards, goal of the character of the energy provide, and it presents measures to minimise defeat of interlocks in a moderately foreseeable formula. Just a few of the issues addressed embody:

• Kinds of interlocking gadgets linked with guards, and their tips of operation
• Necessities for the manufacture and set up of interlocking gadgets with and with out guard locking
• Precept for the assorted of interlocking gadgets
• Measures to minimise the defeat of interlocking gadgets
• Necessities for integration into the preserve watch over gadget

The many and appropriate kind use of a explicit interlocking instrument, from the 5 forms outlined within the typical, is pickle by the possibility review.

What’s unique in ISO 14119:2024?

In the most fresh version of ISO 14119, terminology has been updated, and a few tables were improved and renamed. Below are likely the most different significant adjustments:

• Fault masking criteria (covered by ISO/TR 24119) were constructed-in into Annex J. The same outdated now involves additional particulars on fault masking eventualities and supplies steering for the estimation of the utmost diagnostic protection (DC) values and manufacture steering for the security-linked parts of the preserve watch over gadget (SRP/CS).
• Trapped key interlocking systems, previously covered by ISO/TS 19837, were constructed-in in Annex Okay and were categorised as kind 5 interlocking gadgets. The addition of a novel category kind is a significant update, rising the old classification from four to 5 forms, and highlights the importance of mechanical trapped key interlocking gadgets.

The unique classification of interlocking gadgets in line with the actuation principle and the invent of actuator is summarised in Desk 2 of the typical (more particulars will also be chanced on in ISO 14119:2024).

Nice looking requirements for trapped key interlocking systems discussed in Annex Okay address capability disorders linked to key coding and the reproduction of keys to quit two or more interlocking gadgets from unintentionally sharing an identical key, as this may perchance well lead to publicity to a hazard.

Encourage with ISO 14119 Conception and Application

Fortress is a dash-setter in interlocking solutions, with broad ride in designing and providing trapped key systems tailored to meet the requirements of every application and security requirements, alongside side ISO 14119.

To decrease the possibility of duplicates, Fortress keys have odd codes. Each and every key comes with an engraving to examine its lock, with additional personalisation doable. Fortress also has a database of key codes and their areas to quit the unintended duplication of keys on situation.
