CORRIGENDUM 1
Corrections to the French version appear after the English text. Les corrections à la version française sont données après le texte anglais. Foreword Add the following new table and text after the first table explaining the significance of changes between IEC 60079-2, Edition 6.0, 2014 and IEC 60079-2, Edition 5.0, 2007: The significance of changes between IEC 60079-2, Edition 6.0, 2014 and IEC 61241-4, Edition 5.0, 2007 are as listed below:
Type Changes Clause in 61241-4 Minor and Editorial Changes Extension Major Technical Changes Removed type of protection “pD”.
Included in 3.20, 3.21 and 3.22 3.1
X
Definition of pressurization now accommodates both gas and dust 3.3
X
Definition of protective gas now accommodates both gas and dust 3.4
X
Removed definition for an enclosure.
Defined in IEC 60079-0 3.5 X
Removed note in definition for pressurized enclosure. 3.6 X
Replaced definition of static pressurization with 60079-2 definition 3.7 X
Removed definition for “pressurization with continuous flow of the protective gas”.
Term not used in 61241-4 3.9 X
Removed definition for “electrical apparatus”.
Definition is covered in IEV 3.10 X
Definition of ignition-capable apparatus now accommodates both gas and dust 3.11 X

Type Changes Clause in 61241-4 Minor and Editorial Changes Extension Major Technical Changes Removed definition for “protected apparatus”.
This was only used to address batteries which are now covered in Annex G and Annex H. 3.17 X
Replaced definition of “pressurization system” with 60079-2 definition 3.18 X
Removed definition for “alternate (or auxiliary) source of supply of protective gas”.
Term used is “second source of Supply.
This is now addressed in 60079-2, 9.1 3.19 X
Removed definition for “zones in Area Classification”
This definition is provided in 60079-10-2. 3.20 X
Removed definition for “zone 20 in Area Classification”.
See above 3.21 X
Removed definition for “zone 21 in Area Classification”.
See above 3.22 X
Removed definition for “zone 22 in Area Classification”.
See above 3.23 X
Removed Clause on “Pressurization principle” including sub-clauses.
This information is covered by the definition of “Pressurization”, see 3.13 and other clauses in the standard. 4 X
Removed Clause on “Electrical performance of apparatus”.
Safe performance of equipment is addressed by 60079-0, 6.1 b) 5.1 X
Removed note about equipment with large surface areas subjected to pressures > 1kPa may be subject to pressure vessel legislation. 5.2 X
Text on apertures is equivalently covered by 5.5 and 5.6 5.3 X
Text on electrical connections is equivalently covered in 60079-0, clause 14. 5.4 X
Text on delaying opening of an enclosure because of internal hot surface is equivalently covered in clause 15. 5.5 X
Removed text on providing suitable amount of doors or covers to provide for effective removal of dust from the enclosure.
The text in 61241-4 would not lend itself to consistent assessments from different CBs. 5.5 X
Text on temperature limits is equivalently covered in clause 6
