DANSK DSF/FPREN IEC 60079-19 PDF

This part of IEC 60079 – gives instructions, principally of a technical nature, on the repair, overhaul, reclamation and modification of equipment designed for use in explosive atmospheres; – applies to overhaul and repair which mitigates deficiencies identified during operation, inspection and maintenance, – does not give advice on cable entry systems which may require a renewal when the equipment is re-installed; – is not applicable to type of protection “m” – assumes that good engineering practices are adopted throughout. Where type of protection “m” is used in association with other types of protection e.g. Ex “d”, Ex “e” the relevant clauses of this standard applies for the overhaul & repair of those types of protection but if the Ex “m” equipment is defective it can only be replaced NOTE – Much of the content of this standard is concerned with the repair and overhaul of electrical 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.
