Explanation of the types of changes:
A) Definitions
1) Minor and editorial changes:
• Clarification
• Decrease of technical requirements
• Minor technical change
• Editorial corrections
These are changes which modify requirements in an editorial or a minor technical way. They include changes of the wording to clarify technical requirements without any technical change, or a reduction in level of existing requirement.
2) Extension: Addition of technical options
These are changes which add new or modify existing technical requirements, in a way that new options are given, but without increasing requirements for equipment that was fully compliant with the previous standard. Therefore, these will not have to be considered for products in conformity with the preceding edition.
3) Major technical changes:
• addition of technical requirements
• increase of technical requirements
These are changes to technical requirements (addition, increase of the level or removal) made in a way that a product in conformity with the preceding edition will not always be able to fulfil the requirements given in the later edition. These changes have to be considered for products in conformity with the preceding edition. For these changes additional information is provided in Clause B below.
NOTE These changes represent current technological knowledge. However, these changes should not normally have an influence on equipment already placed on the market.
B) Information about the background of changes
Al — It was determined that this was already covered by the sealed device definition
Cl — Enclosed break devices “nC” are now designated as mdc” and the requirements are
located in IEC 60079-1:2014.
C2 — Type of protection “nATM is now designated as type of protection ec” and the

C3 — Test time for the preparation of non-incendive component samples has been
specified.
C4 — Additional documentation requirements for seals and gaskets.
C5 — As the pressure inside an enclosure fitted with fans can be affected by the
operation of the fan, it is now specified that the restricted breathing test is
conducted with fans operating and stationary.
