Just (08.2019) the long-awaited next edition of the EN 1127-1 standard has been released. The standard, which is the basic standard in the scope of Directive 2014/34 / EU (ATEX), is also harmonized with the machinery directive (MD: 2006/42 / EC). In the case of the MD directive, EN 1127-1 is a type B standard (earlier editions were identified as a type C standard). The most important updates should be the clarification (clearer distinction) between ignition sources “hot surfaces” and “mechanically produced sparks” and new information regarding the assessment of ultrasound sources.
The standard is not yet included in the list of harmonized standards, but it will certainly be.
