Description / Abstract:
This part of IEC 60745 deals with the safety of hand-held
motor-operated or magnetically driven electric tools, the rated
voltage of the tools being not more than 250 V for single-phase
a.c. or d.c. tools, and 440 V for three-phase a.c. tools.
So far as is practicable, this standard deals with the common
hazards presented by handheld tools which are encountered by all
persons in the normal use and reasonably foreseeable misuse of the
tools.
Tools with an electric heating element are within the scope of
this standard. They should also comply with relevant parts of IEC
60335.
Requirements for motors not isolated from the supply, and having
basic insulation not designed for the rated voltage of the tools,
are given in Annex B. Requirements for rechargeable battery-powered
motor-operated or magnetically driven tools and the battery packs
for such tools are given in Annex K. Those for such tools that are
also operated and/or charged directly from the mains or a
non-isolated source are given in Annex L.
Hand-held electric tools, hereinafter referred to as tools,
which can be mounted on a support or working stand for use as fixed
tools without any alteration of the tool itself, are within the
scope of this standard. Requirements for such supports or working
stands are given in Annex M.
This standard does not apply to:
– hand-held tools intended to be used in the presence of
explosive atmosphere (dust, vapour or gas);
– hand-held tools used for preparing and processing food;
– hand-held tools for medical purposes (IEC 60601);
– heating tools which are covered by IEC 60335-2-45.
For hand-held tools intended to be used in vehicles or on board
ships or aircraft, additional requirements may be necessary.
For hand-held tools intended to be used in tropical countries,
special requirements may be necessary.
NOTE Attention is drawn to the fact that in many countries,
additional requirements are specified by the national health
authorities, the national authorities responsible for the
protection of labour, the national water supply authorities,
etc.
1DV DR Addition: Add the following
paragraph:
This standard deals with tools used in non-hazardous
locations in accordance with the National Electrical Code, NFPA 70,
and the Canadian Electric Code, Part 1, CSA C22.1, and General
Requirements – Canadian Electrical Code, Part II, CAN/CSA-C22.2 No.
