What is IEC 61010?

IEC 61010 specifies safety requirements for electrical equipment used in measurement, control, and laboratory applications. While IEC 61326 addresses electromagnetic compatibility for this equipment category, IEC 61010 addresses electrical safety — protection against electric shock, energy hazards, fire, mechanical hazards, and other safety risks that could harm users or damage property.

IEC 61010 is distinct from general electrical safety standards like IEC 62368-1 (AV/IT equipment) or IEC 60335-1 (household appliances) because measurement and laboratory equipment presents unique hazards: users regularly connect it to live circuits, handle high voltages, and make measurements in hazardous electrical environments. The standard's Measurement Category (CAT) system addresses these specific risks systematically.

EN 61010-1 is the European adoption of IEC 61010-1 and is a harmonized standard under the Low Voltage Directive 2014/35/EU, providing presumption of conformity with the LVD's safety essential requirements. IEC 61010 safety testing is therefore typically combined with IEC 61326 EMC testing to complete the full CE marking compliance package for measurement equipment.

Measurement Categories (CAT Ratings)

IEC 61010 introduced the Measurement Category system to address the transient overvoltages present at different points in electrical installations. The CAT rating of an instrument defines the maximum transient overvoltage the instrument must withstand without endangering the user — a critical safety parameter for any equipment connected to live electrical circuits.

CAT I

Signal Level Circuits

Measurements on circuits not directly connected to the distribution mains — equipment connected to specially protected secondary circuits, electronic equipment circuits, battery-powered circuits, and circuits with protective measures against transient overvoltages.

Lowest transient overvoltage requirement
Typical: oscilloscopes measuring audio circuits, data acquisition on sensor outputs

CAT II

Single-Phase Receptacle Level

Measurements on single-phase loads connected to permanently installed electrical outlets — household appliances, portable tools, and similar loads supplied from fixed installation outlets.

Typical: multimeters measuring appliance supply voltages
Higher transient withstand than CAT I
Most handheld multimeters carry at minimum CAT II rating

CAT III

Distribution Level

Measurements in fixed installations — distribution boards, circuit breakers, bus bars, junction boxes, wiring in commercial buildings, and industrial motor control centers supplied from the fixed installation.

Significantly higher transient overvoltage requirement than CAT II
Typical: electricians' instruments used in panel work
Required for equipment used at the distribution board

CAT IV

Service Entrance Level

Measurements at the origin of the low-voltage installation — utility service entrances, electricity meters, primary overcurrent protection devices, and overhead line connections from the utility to the building.

Highest transient overvoltage requirement in the IEC 61010 system
Required for instruments used at the utility connection point
Typical: utility meters and service entrance test equipment

FDA ASCA Accreditation for IEC 61010-1

Compatible Electronics holds FDA Accreditation Scheme for Conformity Assessment (ASCA) accreditation for IEC 61010-1, Ed. 3.1 (2017-01) (FDA#19-34) at the Lake Forest/Silverado location. This is significant for manufacturers of measurement and laboratory equipment that also qualifies as a medical device under FDA jurisdiction.

Under the FDA ASCA program, test reports issued by ASCA-accredited laboratories to recognized consensus standards can be submitted directly with 510(k) premarket notifications. The FDA accepts ASCA-accredited test reports for the cited recognized standard without independent FDA review of the test report — streamlining the premarket submission process and potentially reducing review time.

This is particularly relevant for IVD instruments, laboratory analyzers, and diagnostic measurement equipment that must simultaneously comply with IEC 61010-1 safety requirements and IEC 60601-1-2 or IEC 61326-2-6 EMC requirements for both FDA and EU regulatory submissions.

Real-World Testing Examples

CAT III Clamp Meter — IEC 61010-1 + IEC 61010-2-030 + CE Marking

A test instrument manufacturer needed CE marking under the Low Voltage Directive for a 600 V CAT III clamp meter intended for electricians working in commercial building distribution panels. Compatible Electronics performed the complete IEC 61010-1 Ed. 3.0 safety test suite — dielectric strength at CAT III levels (6 kV impulse per IEC 61010-1 for 600 V CAT III), leakage current under normal and single-fault conditions, creepage and clearance verification for Pollution Degree 2, and temperature testing at maximum rated current. IEC 61010-2-030 particular requirements for the measuring circuits were applied, addressing the specific requirements for the current input circuit. The accredited safety test report, combined with the EN 61326-1 EMC report, completed the full CE marking technical file for the LVD and EMC Directive simultaneously.

Laboratory Oven — IEC 61010-2-010 + EN IEC 61010-2-010 + CE + cCSAus

A laboratory equipment manufacturer needed simultaneous CE marking and North American (UL/CSA) safety certification for a laboratory drying oven operating up to 300°C. Compatible Electronics performed testing to EN IEC 61010-2-010 (2020) for CE marking under the LVD, and to CSA C22.2 No. 1010.1 for North American market access — both from the same test engagement at Lake Forest/Silverado. Key tests included temperature rise of accessible surfaces and internal components at 300°C setpoint, thermal cutout verification, dielectric strength between heating elements and accessible metal parts, leakage current, and protective conductor continuity. The test also confirmed compliance with the oven's Pollution Degree 2 environment assumptions. The dual accredited test reports — EN IEC 61010-2-010 (ILAC MRA recognized for CE marking) and CSA C22.2 No. 1010.1 (for cCSAus listing) — were delivered from a single test session.

Automated IVD Analyzer — IEC 61010-1 ASCA + IEC 61326-2-6 + IEC 60601-1-2

A clinical diagnostics company needed safety and EMC compliance for an automated nucleic acid extraction and PCR system used in hospital molecular diagnostic laboratories. The system required IEC 61010-1 Ed. 3.1 safety testing (FDA ASCA accredited at Compatible Electronics) for 510(k) submission, IEC 61326-2-6 EMC testing for CE marking under the IVDR, and IEC 60601-1-2 Ed. 4 EMC for the medical electrical environment. Compatible Electronics structured an integrated three-standard test plan: IEC 61010-1 Ed. 3.1 safety testing (ASCA accredited), IEC 61326-2-6 + IEC 61326-1 emissions and immunity, and IEC 60601-1-2 Ed. 4 immunity augmentation for the professional healthcare facility environment. All testing was completed at Lake Forest/Silverado in a single extended engagement. The FDA ASCA accredited IEC 61010-1 safety report was submitted directly with the 510(k); the ILAC MRA accredited EMC reports supported the CE marking IVDR technical documentation.
