BS EN 60745-1:2009+A11:2010

BS EN 60745-1:2009 + A11:2010 Hand-held motor-operated electric tools. Safety. General requirements

BS EN 60745-1 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.

BS EN 60745-1 deals with the common hazards presented by hand-held 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 batterypowered 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 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.

BS EN 60745-1 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.
