Overview

oSIST prEN IEC 61010-2-032:2026 is the European draft standard that details the safety requirements for electrical equipment used in measurement, control, and laboratory settings. Specifically, this part – Part 2-032 – addresses the unique safety aspects related to hand-held and hand-manipulated current sensors. Such devices are commonly used for electrical test and measurement tasks, where they measure, detect, or indicate current in circuits without any physical interruption of the circuit path. The standard was developed under the auspices of the International Electrotechnical Commission (IEC) and prepared by technical committee IEC TC 66.

By setting out detailed requirements and test procedures, oSIST prEN IEC 61010-2-032:2026 aims to mitigate the risks associated with using portable current sensors and ensure their safe integration into broader electrical testing and laboratory processes. The requirements supplement the general safety requirements outlined in IEC 61010-1, focusing attention on potential hazards unique to hand-held measurement equipment, such as electric shock, mechanical stresses, fire, and misuse.

Key Topics

oSIST prEN IEC 61010-2-032:2026 covers several crucial aspects specific to hand-held current sensors used for electrical test and measurement, including:

• Definitions and Terminology
  Comprehensive definitions for equipment (such as "hand-held," "clamp multimeter," and "jaw"), circuits (e.g., "measuring circuit"), and safety concepts (like "high integrity" and "measurement category").

• Assessment, Testing, and Environmental Conditions
  Procedures for verifying performance and safety under various environmental and fault conditions.

• Marking and Documentation
  Clear labeling requirements for terminals, measurement categories, and sensor types, aiding in user awareness and proper use.

• Protection Against Hazards
  Criteria to prevent electric shock, mechanical injuries, spread of fire or arc flash, and exposure to hazardous substances.

• Construction and Performance
  Requirements on design features such as insulation, interlocks, and resistance to mechanical stress.

• Categories and Compatibility
  Guidance on measurement categories (e.g., CAT II, CAT III, CAT IV) and operational voltages.

• Guidance on Misuse
  Consideration for reasonably foreseeable misuse scenarios to ensure robust protection even if equipment is not used as intended.

Applications

oSIST prEN IEC 61010-2-032:2026 is essential for manufacturers, testing laboratories, and certification bodies involved with:

• Designing and Producing Hand-held Current Sensors
  Ensures new products comply with international safety expectations for electrical test equipment, including current clamps and probes.

• Quality Assurance and Compliance Testing
  Testing organizations rely on the standard to evaluate whether devices provide the necessary level of safety for end users, especially in industrial, laboratory, or field environments.

• Laboratory and Industrial Electrical Testing
  Lab and field engineers can select compliant current sensors, ensuring safety during diagnostic, maintenance, and troubleshooting activities involving live circuits.

• Equipment Integration
  For manufacturers combining current sensors as part of broader assemblies (multimeters, process control), this standard provides a harmonized approach to integrating safety measures.

• Instruction and Documentation
  The standard underpins clear device marking and user manuals, supporting safe everyday operation and reducing misuse risks.

Related Standards

oSIST prEN IEC 61010-2-032:2026 is part of a broader family of standards addressing electrical safety in measurement, control, and laboratory settings:

• IEC 61010-1 – General safety requirements for electrical equipment for measurement, control, and laboratory use.
• IEC 61010-2-030 – Requirements for testing and measuring circuits.
• IEC 61010-2-033 – Requirements for hand-held multimeters and similar equipment.
• IEC 61010-2-034 – Requirements for insulation resistance measurement and test equipment.
• IEC 61010-031 – Safety requirements for hand-held probe assemblies for electrical measurement and test.

358 TERMINALS may have a RATED voltage or a RATED current, or both, within that set, and each
359 individual TERMINAL may have a RATED voltage to earth. For some current sensors, the RATED
360 voltage between TERMINALS may be different from the RATED voltage to earth. Markings shall be
361 clear to avoid misunderstanding.
362 Some MEASURING CIRCUIT TERMINALS for the current sensor within the scope of this document
363 also serve as output TERMINALS.
364 Except as permitted in 5.1.5.101.4:
365 a) each pair or set of MEASURING CIRCUIT TERMINALS that are intended to be used together shall
366 be marked with the value of the RATED voltage or the RATED current, as applicable; and
367 b) MEASURING CIRCUIT TERMINALS RATED for MEASUREMENT CATEGORIES shall be marked with the
368 value of the RATED nominal AC RMS line-to-neutral or DC voltage of MAINS as specified in
369 5.1.5.101.2, and other MEASURING CIRCUIT TERMINALS shall be marked with the value of the
370 RATED voltage to earth; and
371 c) each individual, pair, or set of MEASURING CIRCUIT TERMINALS shall be marked with the
372 pertinent numeral of the MEASUREMENT CATEGORY as specified in 5.1.5.101.2 or with the
373 symbol 14 of Table 1 as specified in 5.1.5.101.3, if applicable.
374 Markings shall be placed adjacent to the TERMINALS. However, if there is insufficient space (as
375 in multi-input current sensor), the marking may be on the RATING plate or scale plate, or the
376 TERMINAL may be marked with symbol 14 of Table 1.
377 Any set of MEASURING CIRCUIT TERMINALS does not need to be marked symbol 14 of Table 1
378 more than once, if it is close to the TERMINALS.
379 Conformity is checked by inspection and, if applicable, as specified in 5.1.5.101.2 and
380 5.1.5.101.3, taking the exceptions in 5.1.5.101.4 into account.
