Overview
EN 61010-031:2015/A11:2021 is a CLC/CENELEC amendment to the IEC 61010 series that defines safety requirements for hand‑held and hand‑manipulated probe assemblies used for electrical test, measurement and laboratory applications. The standard covers probe assemblies and related accessories that provide direct electrical connection between a test point and measurement equipment, whether fixed or detachable. It clarifies ratings, insulation, testing and documentation needed to demonstrate safe use across expected voltage and current ranges.
Key topics and technical requirements
- Scope and probe types: The standard formally classifies probe assemblies into four types:
- Type A - non‑attenuating, low- and high‑voltage probes rated up to 63 kV (no voltage divider).
- Type B - high‑voltage attenuating/divider probes, rated >1 kV r.m.s. (up to 63 kV).
- Type C - low‑voltage attenuating/divider probes, rated ≤1 kV r.m.s.
- Type D - low‑voltage probes (≤30 V r.m.s.) suitable for currents >8 A, can be attenuating/non‑attenuating.
- Exclusions: Current sensors covered by IEC 61010‑2‑032 are excluded (though input leads/accessories may fall under EN 61010‑031).
- Insulation and materials: Manufacturers are required to select insulating materials with the probe’s expected service life in mind.
- Voltage and impulse testing: Amendment A11 references EN 61180:2016 for test equipment and specifies that voltage testers must maintain regulated output within ±5% during AC and 1 min DC tests. The impulse test uses a 1.2/50 µs waveform per EN 61180.
- Documentation and marking: Safe usage information, rated voltages/currents and assembly instructions must be provided to support correct assembly and safe use.
- Harmonization: Annex ZZ maps this standard to the safety objectives of Directive 2014/35/EU (Low Voltage Directive), aiding conformity assessment in the EU.

The EN 61010-031:2015/A11:2021 standard serves a critical role in ensuring safety for electrical equipment utilized in measurement, control, and laboratory environments. It specifically addresses the safety requirements for hand-held and hand-manipulated probe assemblies, highlighting the importance of proper protocols for devices that establish direct electrical connections between a component and test or measurement equipment. The scope of this standard is comprehensive, categorizing probe assemblies into four distinct types: Type A, Type B, Type C, and Type D. Each type is tailored for specific voltage and functionality requirements, thereby ensuring that safety is maintained across a range of applications. Type A deals with non-attenuating probe assemblies rated for high voltage, while Type B focuses on attenuating or divider probe assemblies capable of handling higher voltage ranges. Type C further narrows down to low-voltage attenuating or divider assemblies, and Type D specifies requirements for low-voltage assemblies suitable for higher current applications. This classification not only enhances clarity for manufacturers and users but also fosters safer practices in electrical testing and measurement. One of the key strengths of the EN 61010-031 standard is its explicit safety directives, which incorporate essential features like overload protection through components such as fuses. This ensures that probe assemblies are equipped to handle surges and other potentially hazardous situations. Furthermore, the inclusion of guidance on signal conditioning and component functions aids users in selecting the appropriate equipment according to their specific needs, ultimately promoting safety and reliability in electrical testing. Moreover, the standard provides useful exclusions, explicitly stating that it does not cover current sensors per IEC 61010-2-032, while still allowing applicability to input measuring circuit leads and accessories. This distinction helps clarify the usability of the standard in various contexts, enhancing its relevance to professionals in electrical testing fields.
