1 Scope
This standard specifies the terms and definitions, model preparation methods, basic
parameters, technical requirements, test methods, signs, instruction manuals, packaging,
transport, storage, handling of hand-held chain-saws with lithium-ion battery as power
source (hereinafter referred to as chain-saws with lithium-ion battery).
This standard applies to hand-held chain-saws, which are operated by a single person,
for sawing branches, wood and similar materials; are powered by a rechargeable
lithium-ion battery pack (battery pack) with a nominal voltage not greater than DC 75V,
under normal environmental conditions.
This standard does not apply to.
- Lithium-ion chain-saws for one-handed operation and/or for use at heights, such as
in trees;
- Hand-held chain-saws, which are powered by user-installed universal battery packs
or battery packs;
- Other hand-held chain-saws, which are powered by non-lithium-ion batteries.
