Main Changes in the ISO 14119 Standard for Interlocking Devices

PUBLISHED 06/19/2025

The upgraded ISO 14119:2024 favored– concealing interlacing devices connected with guards– came to be published specific a couple of months back, altering the 2013 design. This modification is important for device contractors, discontinue customers, and safety and security experts.

The adjustments were likewise stated in a fresh webinar organized by Citadel Safety– peer the recording right here when you neglected it.

The usual covers the recordsdata for the stem and choice of interlacing devices connected with guards, simply of the nature of the power resource, and it pays for procedures to reduce loss of interlocks in a relatively near fashion. A few of the concerns resolved have:

• Kinds of interlacing devices connected with guards, and their pointers of procedure
• Demands for the stem and establish of interlacing devices with and with out guard securing
• Concept for the choice of interlacing devices
• Steps to reduce the loss of interlacing devices
• Demands for combination right into the safeguard supervise device

The choice and valid order of a specific interlocking device, from the 5 kinds detailed within the preferred, is room by the discomfort evaluation.

What’s fresh in ISO 14119:2024?

In the most recent design of ISO 14119, terms has actually been upgraded, and a couple of tables were boosted and relabelled. Below are amongst the contrary important adjustments:

• Mistake concealing demands (covered by ISO/TR 24119) were incorporated right into Annex J. The usual currently entails extra small print on mistake concealing circumstances and pays for guiding for the estimate of primarily one of the most analysis protection (DC) worths and stem guiding for the protection-linked formula of the safeguard supervise device (SRP/CS).
• Entraped vital interlocking systems, formerly covered by ISO/TS 19837, were incorporated in Annex K and were categorized as kind 5 interlocking devices. The enhancement of a fresh course kind is an important upgrade, increasing the previous category from 4 to 5 kinds, and highlights the importance of mechanical entraped vital interlocking devices.

Entraped vital interlacing relies upon the enforcement of a chain of procedures in a fixed analyze by the button of secrets that are either entraped or launched earlier than the succeeding action within the series might well furthermore be carried out.

The fresh category of interlacing devices in conformity to the actuation concept and the design of actuator is summed up in Table 2 of the preferred (additional small print might well furthermore be conceal in ISO 14119:2024).

Eye-catching requirements for entraped vital interlocking systems stated in Annex K emulate capacity factors connected to vital coding and the recreation of secrets to stop 2 or additional interlocking devices from accidentally sharing an a similar trick, as this might well possibly repercussion in direct exposure to a risk.
