NOTES
1. The first periodic review shall be carried out no later than within the period specified in
the table after their commissioning.
2. In the case of very frequent use of electric hand tools (for example, the tool is
operated for more than 250 operating hours per year), it is advisable to set shorter
periods for periodic reviews by means of local operating safety regulations.
3. The intervals of inspections and reviews are applied also in the case of electrical
appliances that are being leased on a long-term basis.
4. Inspections and reviews apply also to extension cables and detachable power supply
cords. If the power cord is equipped with a protective conductor, its integrity and
resistance is reviewed and the same intervals apply as in the case of appliances of
protection class I.
5. With respect to extension cables, the intervals of periodic reviews shall be set the
same as the intervals applicable to handheld appliances. With respect to detachable
power cords, the intervals of periodic reviews shall be set the same as the intervals
applicable to the appliance with which such power cords are being used.
14
6. Electrical appliances operated during the warranty period (as prescribed by the law,
manufacturer or seller) shall be reviewed only within the scope not requiring any
intervention in their construction. The inspection is carried out pursuant to Art. 6.3.1
of the standard and in addition to such inspection, electric parameters are measured.
The review interval is counted since their commissioning.
7. In the case of appliances of protection class I and in the case of extension cables and
detachable power cords, it is recommended to verify the continuity of the protective
conductor before their commissioning.
8. The intervals of periodic reviews may possibly be determined differently based on a
risk analysis.

possibility of any contact under voltage is excluded. Each appliance may only
be operated in the environment specified by the manufacturer.
3. If an unsatisfactory condition is found during an inspection, the electrical
appliance shall be taken out of service and visibly marked. Non-functional
appliances must be reported to the person responsible for the given appliance.
Re-commissioning is only possible after repair, subject to confirmation of
a safe state by means of a review.
4. If at any time during the use of electrical appliances a fault is found in the
appliance, e.g. insulation damage, burn odor, smoke, unusually noisy or irregular
or shock operation, strong hum, jerky start, excessive heating of some parts,
sparking, electric tingling, it is necessary to switch off the electrical device and
report the fault - proceed according to point 3 of this Annex.
5. In the event of a fall of the appliance, it is necessary to perform its thorough
inspection before its re-commissioning.
