This standard applies to hand-held rechargeable battery-powered, motor-operated or magnetically driven tools intended for indoor or outdoor use designed for use by one person and the battery packs for such tools including those intended to be charged from chargers with a non-isolated output with an output voltage of not more than 250 volts. Battery operated tools which can be operated while connected to the mains shall also comply with EN 50144-1. This Part 1 is to be used in conjunction with the appropriate Part 2, which contains clauses which supplement or modify the corresponding clauses in Part 1 to provide the complete requirement for each sort of tool. It also applies, as far as is reasonable, to tools not mentioned in Part 2 and to those designed on basically new principles in which case additional requirements may be necessary. This standard covers tools which can be used in a fixed support. Unless the requirement for such a support is given in a relevant Part 2, this standard alone will not be sufficient to ensure that the combination of tool and support is adequate. Tools or battery packs incorporating battery chargers are also within the scope of this standard but such tools and packs are also required to comply with EN 60335-2-29. This standard does not apply to: - tools used for preparing or processing food; - tools used in explosive atmospheres. It does not apply to a general purpose battery that may be purchased and installed by the user. It does not apply to battery chargers.
