IEC 62863:2017 pdf download.Method of measuring performances of electric hair clippers or trimmers for household use
1 Scope
This document applies to reciprocating electric hair clippers or trimmers for household use. This document deals with the methods of measuring performances of electric hair clippers or trimmers for household use with a rated voltage not greater than 250V. This document does not specify safety or performance requirements. This document does not apply to professional hair clippers or trimmers, animal shearers and animal clippers, or shavers. For shavers, refer to IEC 61 254. NOTE This document does not cover safety requirements (see IEC 60335-2-8).

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply. ISO and IEC maintain terminological databases for use in standardisation at the following addresses: • IEC Electropedia: available at http://www.electropedia.org/ • ISO Online browsing platform: available at http://www.iso.org/obp 3.1 clipper trimmer appliance that is designed to cut hair that consists of a motor, drive system, fixed blade containing teeth and a moving blade containing teeth moving in a reciprocating motion intended for clipping/trimming, not shaving Note 1 to entry: Depending on the specific function, clippers are also called trimmers.3.2 battery-operated hair clipper battery-operated hair trimmer hair clipper or trimmer deriving its energy solely from primary batteries or secondary batteries and not designed for connection to the mains supply or a charger, or from the battery packs that are supplied by manufacturers together with the hair clipper or trimmer Note 1 to entry: If the manufacturer supplies a specific charger and rechargeable batteries with the clipper or trimmer, the combined device is considered as a rechargeable hair clipper or trimmer when performance is measured.3.3 rechargeable hair clipper rechargeable hair trimmer hair clipper or trimmer powered by rechargeable batteries or battery packs that are recharged in the hair clipper or trimmer Note 1 to entry: There are two types, cordless rechargeable hair clipper or trimmer and cord/cordless rechargeable hair clipper or trimmer. 3.4 cordless rechargeable hair clipper cordless rechargeable hair trimmer rechargeable hair clipper or trimmer that is not intended to run while connected to the mains supply or a charger 3.5 cord/cordless rechargeable hair clipper cord/cordless rechargeable hair trimmer cordless rechargeable hair clipper or trimmer that can be operated while connected to the mains supply with discharged batteries 3.6 corded hair clipper corded hair trimmer hair clipper or trimmer without batteries or battery packs, that can operate only while connected to the mains supply 3.7 cool state state in which one hour passes after the outside of the device has fallen to ambient temperature 3.8 stationary blade tooth plane SEE: Figure 1 .
4 General conditions for the tests
4.1 General
Unless otherwise specified, the tests are carried out in accordance with Subclauses 4.1 to 4.8.Unless otherwise specified, the tests are carried out when the controller of the hair clipper or trimmer is set to the highest setting. 4.2 Pre-conditioning For rechargeable hair clippers, preconditioning shall be carried out according to 5.2.1 before performing the tests specified in this document. For hair clippers or trimmers other than rechargeable types, a preconditioning run shall be carried out according to 5.2.2 before performing the tests specified in this document. 4.3 Battery condition For battery-operated hair clippers or trimmers, new batteries shall be used, unless otherwise specified. For rechargeable hair clippers or trimmers, the battery shall be fully charged before each test according to the manufacturer’s instructions. 4.4 Test environment The tests are carried out in draft-free indoor environment at an ambient temperature of (23 ± 2) °C. 4.5 Limits of voltage variation During the test, the variation in the voltage shall not exceed ± 1 % of the test voltage. 4.6 Test voltage Unless otherwise specified, the tests are carried out at a specific voltage within a voltage range (e.g. 1 00 V to 240 V) or at the rated voltage or voltages (e.g. 1 20 V, or 1 20 V and 240 V). 4.7 Test frequency Hair clippers or trimmers are tested at the rated frequency or within a rated frequency range (e.g. rated as 50 Hz and 60 Hz, or 50 Hz to 60 Hz). 4.8 Test electrical supply system Total harmonic distortion of the test electrical supply system shall be less than 5 %.
