Scope and object IEC 61010-1:2010, Clause 1 and IEC 61010-1:2010/AMD1:2016, Clause 1 apply except as follows: 1.1.1 Equipment included in scope Replace the existing text with the following: This group safety publication is primarily intended to be used as a product safety standard for the products mentioned in the scope, but shall also be used by technical committees in the preparation of their publications for products similar to those mentioned in the scope of this document, in accordance with the principles laid down in IEC Guide 104 and lSO/lEC Guide 51. This part of IEC 61010 specifies safety requirements for HAND-HELD multimeters for domestic and professional use, capable of measuring MAINS. HAND-HELD multimeters are multi-range multifunction measuring instruments intended to measure voltage and other electrical quantities such as resistance or current. Their primary purpose is to measure voltage on a live MAINS. They are suitable to be supported by one hand during NORMAL USE. 1.1.2 Equipment excluded from scope Add the following new item to the list and the following paragraph: aa) IEC 61557 (all parts), Electrical safety in low voltage distribution systems up to 1 000 V a.c. and 1 500 V d.c. – Equipment for testing, measuring or monitoring of protective measures HAND-HELD EQUIPMENT such as oscilloscopes, wattmeters, process control multimeters not RATED for measuring voltage on a live MAINS, clamp multimeters and communications test sets are not within the scope of this document. 1.2.1 Aspects included in scope Replace item c) of the second paragraph with the following new item: c) spread of fire or arc flash from the HAND-HELD multimeters (see Clause 9); Replace the third paragraph with the following two new paragraphs: Requirements for protection against HAZARDS arising from NORMAL USE, REASONABLY FORESEEABLE MISUSE and ergonomic factors are specified in Clause 16 and Clause 101. Annex BB provides guidance to equipment manufacturer on HAZARDS that should be considered for equipment intended for performing tests and measurements on hazardous conductors, including MAINS conductors and telecommunication network conductors
