Annex K – (normative) – Battery tool and battery packs
K.1 Scope
This annex applies to rechargeable battery-powered motor-operated or magnetically driven tools and the
battery packs for such tools. This annex applies to tools incorporating detachable, integral and separable
battery packs. The maximum rated voltage for tools and battery packs is 75 V d.c.
Battery tools covered by this annex are not considered to be class I, class II, or class III tools and
therefore are not required to have basic, supplementary or reinforced insulation. Electric shock hazard is
considered to only exist between parts of opposite polarity.
Battery packs for tools covered under this annex intended to be charged by a non-isolated charger shall
be evaluated by this annex and standard. When evaluating a battery pack for protection against electric
shock, creepage distances, clearances and distances through insulation, the battery pack shall be fitted
to the intended charger.
All clauses of this standard apply unless otherwise specified in this annex. If a clause is stated in the
annex, the requirements replace the requirements of the standard.
For the purpose of the tools covered by this annex, the term mains switch as it appears in the standard
is understood to refer to the power switch of the battery operated tool.
This annex is not intended to apply to tools using general purpose batteries installed by the user and this
annex alone will not be sufficient to ensure all hazards are considered for these products’ “battery packs”.
This annex does not apply to battery chargers which are covered by IEC 60335-2-29.
