EN 1088 will soon be superseded by EN ISO 14119
The new EN ISO 14119 standard
The currently valid EN 1088 will soon be superseded by EN ISO 14119.
Both standards provide assistance in the assessment of interlocking devices on movable safety guards.
In addition to EN ISO 14119, all other valid standards taken into account for assessing the “guard locking” safety function will be introduced briefly below.
The “main standard” in connection with safety doors is currently EN 1088, “Safety of machinery - Interlocking devices associated with guards - Principles for design and selection”.
This standard has existed since 1995 and was most recently supplemented and published in 2005.
The date of the standard is now 2008, but only legal adaptations to the modified Machinery Directive have been added. In terms of content, virtually nothing has changed since the initial publication.
A fundamental revision of EN 1088 has been in progress for several years.
The draft appeared in the year 2011 under a new number - prEN ISO 14119.
The final version is scheduled to appear in early 2013. It has again undergone extensive revisions compared to the draft version.
Several key changes will be introduced briefly over the course of this article
ISO 14119:2013
Safety of machinery - Interlocking devices associated with guards - Principles for design and selection
ISO 14119:2013 specifies principles for the design and selection independent of the nature of the energy source of interlocking devices associated with guards.
It covers the parts of guards which actuate interlocking devices. It does not necessarily provide all the specific requirements for trapped key systems.
ISO 14119:2013 provides measures to minimize defeat of interlocking devices in a reasonably foreseeable manner.
