ISO 14119 for interlocking devices associated with guards has arrived

摘要

The new standard "ISO 14119:2013 Safety of machinery - Interlocking devices associated with guards - Principles for design and selection" has arrived and will replace EN 1088 within 18 months. David Collier CMSE, Business Development Manager at Pilz UK and chairperson of the Machinery Safety Alliance, explains what it will mean for machine builders. Although there is an 18 month transition from EN 1088, machine builders who design safety gate systems will be at an advantage if they aim to comply with the new ISO 14119 immediately. Technologies exist which can overcome challenges, like fault masking, and when deployed can provide added peace of mind as well as compliance with the more exacting requirements of this new standard. In contrast to the previous standard EN 1088, ISO 14119 considers additional technologies such as RFID or electromagnetic guard locking, classifies interlocking switches and regulates more clearly the specifications for installing guards. These regulations are particularly significant with regard to protection against guard manipulation, also known as defeating of guards. ISO 14119 will replace all national standards on this subject and will be valid worldwide. Formally this signifies a huge step forwards: the old standard was purely European, whereas the new standard is published by ISO. There are too many technical differences between EN 1088 and ISO 14119 to be detailed here, but there follows a taste of some of these differences.
