1.1 Scope
1.1.1 Equipment included in scope
Replace the existing text of 1.1.1 with the following new text:
This part of IEC 61010 specifies safety requirements for equipment for measuring insulation resistance and for equipment for testing electric strength which have an AC or a DC output voltage exceeding 50 V or 120 V respectively.
This document also applies to combined measuring equipment which has an insulation resistance measurement function or an electric strength test measurement function.
This group safety publication focusing on safety essential requirements is primarily intended to be used as a product safety standard for the products mentioned in the scope, but is also intended to be used by technical committees in the preparation of 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 ISO/IEC Guide 51.
One of the responsibilities of a technical committee is, wherever applicable, to make use of basic safety publications or group safety publications, or both, in the preparation of its publications.
1.1.2 Equipment excluded from scope
Add the following two new items after item h) of the list in 1.1.2:
aa) IEC 61557-8, (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 –  Part 8: Insulation monitoring devices for IT systems);
bb) IEC 61557-9, (Electrical safety in low voltage distribution systems up to 1 000 V AC and 1 500 V DC – Equipment for testing, measuring or monitoring of protective measures – Part 9: Equipment for insulation fault location in IT systems).
1.2.1 Aspects included in scope
Replace item c) and item h) from the list of the second paragraph of 1.2.1 with the following new item c) and item h):
c) spread of fire or arc flash from the equipment (see Clause 9);
h) HAZARDS related to the use and REASONABLY FORESEEABLE MISUSE of the equipment (see Clause 16 and Annex BB).
Insert the following new paragraph between the third paragraph and the NOTE of 1.2.1:
Annex BB and Annex CC are informative and address HAZARDS associated with equipment intended for performing tests and measurements on hazardous conductors, including MAINS conductors and telecommunication network conductors.
1.2.2 Aspects excluded from scope
Add a new item aa) after item h) of the list ins 1.2.2:
aa) HAZARDS related to the use by pupil OPERATORS in educational establishments (see IEC 61010-2-130).
