Overview

EN IEC 61010-2-034:2021/A11:2021 is a critical European safety standard developed by the European Committee for Electrotechnical Standardization (CLC). This amendment to EN IEC 61010-2-034:2021 specifies particular safety requirements for electrical equipment used in measurement, control, and laboratory settings, focusing on devices that measure insulation resistance and test electric strength. It applies especially to equipment with output voltages exceeding 50 V AC or 120 V DC, including combined instruments featuring insulation resistance or electric strength test functions.

The standard plays a vital role in ensuring product safety and conformity with the EU Low Voltage Directive 2014/35/EU, providing manufacturers and technical committees with guidelines aligned to IEC Guide 104 and ISO/IEC Guide 51 principles. It includes detailed technical specifications to minimize risks associated with the use of high-voltage test equipment in laboratory and industrial environments.

Key Topics

• Scope and Applicability
  • Covers measurement equipment for insulation resistance and electric strength testing with regulated outputs.
  • Applies to both standalone devices and combined measuring instruments with relevant functions.
• Voltage Test Requirements
  • The standard requires that voltage testers maintain regulated output within ±5% of the specified test voltage during both AC and DC tests, ensuring consistent and safe testing conditions.
• Material and Design Considerations
  • Manufacturers are advised to select insulating materials that consider the expected service life of the equipment to maintain long-term safety and functionality.
• Conformity with EU Regulations
  • The standard aligns with Directive 2014/35/EU to ensure safe market availability of electrical equipment meeting essential safety objectives.
• Annexes and References
  • Includes normative references to other IEC publications relevant to electrical test and measurement equipment safety.
  • Informative annexes detail the relationship between the standard and EU safety directives, supporting compliance and regulatory acceptance.

Applications

EN IEC 61010-2-034:2021/A11:2021 is applicable across various fields that require precise and safe measurement of insulation resistance and electric strength:

• Electrical and Electronic Testing Laboratories
  Ensures that test instruments used for verifying insulation integrity and dielectric strength comply with safety requirements to protect operators and equipment.
• Industrial Quality Control and Maintenance
  Enables manufacturers and maintenance teams to safely assess electrical insulation and withstand voltage properties during production and service inspections.
• Chemical and Research Laboratories
  Supports safety in environments where electrical measurement equipment is routinely used for controlling laboratory processes and testing.
• Product Design and Manufacturing
  Guides technical committees and manufacturers in the design, testing, and certification of compliant electrical test equipment.

Related Standards

• EN IEC 61010-1 - General safety requirements for electrical measurement, control, and laboratory equipment.
• EN IEC 61010-2-032 - Particular requirements for hand-held and hand-manipulated current sensors for electrical test and measurement.
• IEC Guide 104 and ISO/IEC Guide 51 - Principles for standardization and safety aspects related to product standards.
• EU Directive 2014/35/EU - Low Voltage Directive setting essential safety objectives for electrical equipment marketed in the European Union.

By adhering to EN IEC 61010-2-034:2021/A11, manufacturers, technical experts, and regulatory bodies ensure that insulation resistance and electric strength test equipment operate safely and reliably, reducing electrical hazards while maintaining compliance with European safety legislation. This standard is essential for advancing safety in electrical measurement technologies worldwide.
