IEC 60079-26 has been published with a major extension
The scope of the standard was extended for separation elements between all EPLs for Gas and Dust hazardous areas as well as for non-electrical equipment.
Suffice to say IEC 60079-26 now covers just about everything and may have a good deal of impact on the certication of certain types of equipped that often contain flammable atmospheres such as pumps or dust conveying equipment.
There are numerous other changes including ‘major technical changes ‘ that may prompt for re-certication (concerning equipment with partition walls of a certain construction).
If in doubt, consult with your issuing Certication Body who should be advising you on the update.
