IEC 62841-3-7-2020 Electric motor-operated hand-held tools, transportable tools and lawn and garden machinery – Safety – Part 3-7: Particular requirements for transportable wall saws. This clause of Part 1 is applicable, except as follows: Replacement of the third paragraph: The rated voltage is not more than 250 V for single-phase a.c. or d.c. tools, and 480 V for three-phase a.c. tools. Addition: This document applies to transportable wall saws guided by a track guiding system intended for dry cutting or to be connected to a liquid system for cutting concrete, stone or similar material by means of a diamond wheel. The rated speed of the diamond wheel does not exceed a peripheral speed of 1 00 m/s at rated capacity. This document does not apply to transportable wall saws that are intended to be left unattended while performing an operation. This document does not apply to transportable wall saws that employ hydraulic systems. This document does not apply to hand-held cut-off machines. NOTE 1 01 Hand-held cut-off machines will be covered by a future part of IEC 62841 -2. 2 Normative references This clause of Part 1 is applicable, except as follows: Replacement of normative reference ISO 3744: ISO 3744:201 0, Acoustics – Determination of sound power levels and sound energy levels of noise sources using sound pressure – Engineering methods for an essentially free field over a reflecting plane Replacement of normative reference ISO 11201: ISO 1 1 201 :201 0, Acoustics – Noise emitted by machinery and equipment – Determination of emission sound pressure levels at a work station and at other specified positions in an essentially free field over a reflecting plane with negligible environmental corrections IEC 61 008-1 :201 0, Residual current operated circuit-breakers without integral overcurrent protection for household and similar uses (RCCBs) – Part 1: General rules IEC 61 008-1 :201 0/AMD1 :201 2 IEC 61 008-1 :201 0/AMD2:201 3 IEC 62841 -1 :201 4, Electric motor-operated hand-held tools, transportable tools and lawn and garden machinery – Safety – Part 1: General requirements ISO 6603-1 , Plastics – Determination of puncture impact behaviour of rigid plastics – Part 1: Non-instrumented impact testing 3 Terms and definitions ISO and IEC maintain terminological databases for use in standardization at the following addresses: • IEC Electropedia: available at http://www.electropedia.org/ • ISO Online browsing platform: available at http://www.iso.org/obp This clause of Part 1 is applicable, except as follows:...
