10.1 Tools shall start under all normal voltage conditions which may occur in use.Compliance is checked by starting the tool 10 times at no-load in succession at a voltage equal to 0,85 times the lowest rated voltage or 0,85 times the lower limit of the rated voltage range, control devices other than speed controls, if any, being set as in normal use.Tools shall in addition be started 10 times in succession at a voltage equal to 1,1 times rated voltage. IEC 62841-1:2014 © IEC 2014 – 37 –The interval between consecutive starts is made sufficiently long enough to prevent undue heating.In all cases, the tool shall operate and overload protection devices incorporated in the tool shall not activate. Centrifugal and other automatic starting switches, if any, shall operate reliably, and without contact chattering.10.2 Tools shall not draw excessive input current during starting that could lead to nuisance operation of facility mains over-current protection devices.Compliance is checked by starting the tool once at rated voltage and no-load with any speed controls set for maximum speed and all other control devices set as in normal use.The current drawn by the tool at (2,0 0,2) s after starting shall not exceed the greater of 30 A or 4 times the rated current of the tool.
