Scope and object

This clause of Part 1 is applicable except as follows: 

Equipment included in scope

Replacement:

Replace the existing text with the following:

This part of IEC 61010 specifies safety requirements for METERS.

The METERS that have a primary purpose of measuring voltage on a live MAINS CIRCUIT are within the scope of this standard. They have various names, but all of them have capability for measurements of voltages on a live MAINS CIRCUIT. Some of the names given to this equipment are as follows:

- MULTIMETER;

- digital MULTIMETER;

- VOLTMETER;

- clamp METER (see also Part 2-032).

For the purpose of this standard, the term METER is used for these HAND-HELD measuring instruments.

NOTE Parts of the equipment that are not within the scope of this Part 2-033 are considered to be covered by the requirements of Part 1 or other part 2's of IEC 61010 and then will also need to meet the requirements of these other parts.

Equipment excluded from scope

Addition:

Add the following new item to the list:

aa) IEC 61557 (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 - Parts 1 through 12).

Addition:

Add the two following paragraphs at the end of the subclause:

Equipment that is not capable of measuring MAINS voltages is not within the scope of this Part 2-033. See IEC 61010-2-030 for requirements pertaining to such equipment.

Such equipment, including other HAND-HELD equipment such as oscilloscopes, wattmeters, process control MULTIMETERS, and communications test sets is not within the scope of this Part 2-033.

Aspects included in scope

Addition:

Add the following paragraph at the end of the subclause:

Requirements for protection against HAZARDS resulting from NORMAL USE and REASONABLY FORESEEABLE MISUSE of measuring circuits are given in Clause 101.
