1 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
This document specifies safety requirements for hand-held and hand-manipulated current sensors intended for measuring, detecting or injecting current, or indicating current waveforms on circuits without physically opening the current path of the circuit being measured.
These current sensors are hand-manipulated before and/or after a test or measurement, but are not necessarily hand-held during the test or measurement. They can be stand-alone current sensors or accessories to other equipment or parts of combined equipment. These include measurement circuits which are part of electrical test and measurement equipment, laboratory equipment, or process control equipment.
NOTE 1 Combined equipment is equipment that is electrically connected to a current sensor by means of a permanent connection which can be detached only by the use of a tool.
NOTE 2 Some current sensors are also known as current clamps, clamp multimeters and current probes.
The types of current sensors covered by this document are defined in Annex FF.
1.1.2 Equipment excluded from scope
This document does not apply to current sensors used as fixed equipment.
1.2.1 Aspects included in scope
spread of fire or arc flash from the current sensor (see Clause 9);
Requirements for protection against hazards arising from normal use, reasonably foreseeable misuse and ergonomic factors are specified in Clause 16, Clause 101 and Annex GG.
Annex BB provides guidance to equipment manufacturers on hazards that should be considered for equipment intended for performing tests and measurements on hazardous conductors, including mains conductors and telecommunication network conductors.
