IEC 60745-2-5:2010 deals with the safety of hand-held motor-operated or magnetically driven electric tools, specific requirements for all types of circular saws. The rated voltage being not more than 250 V for single-phase a.c. or d.c., and 440 V for three-phase a.c. tools. This standard does not apply to saws used with abrasive wheels. The principal changes in this edition as compared with the fourth edition are as follows: – clause 17 introduction of endurance tests in practical use for the guards of all types of saws; – clause 19 clarifications and editorial improvements in respect to the guarding; – annex M editorial improvements. This publication is to be read in conjunction with \/2.<\/p>\n
