Electrical Apparatus for Explosive Gas Atmospheres Part 19: Repair and Overhaul for Apparatus Used in Explosive Atmospheres (Other Than Mines or Explosives)
|Publication Date:||1 September 1993|
|ICS Code (Electrical apparatus for explosive atmospheres):||29.260.20|
This part of IEC 79:
- gives instructions, principally of a technical nature, on the repair, overhaul, reclamation and modification of a certified apparatus designed for use in explosive atmospheres (other then mining applications or explosive processing and manufacture);
- is not applicable to maintenance, other than when repair and overhaul cannot be disassociated from maintenance, neither does it give advice on cable entry systems which may require renewal when the apparatus is re-installed;
- assumes that good engineering practices are adopted throughout.
NOTE - Much of the content of this standard is concerned with the repair and overhaul of electrical rotating machines. This is not because they are the most important items of explosion-protected equipment but rather because they are often major items of repairable capital equipment in which, whatever type of protection is involved, sufficient commonality of construction exists as to make possible more detailed instructions for their repair, overhaul, reclamation or modification.
