Overview
IEC 61340-4-6:2025 is an international standard published by the International Electrotechnical Commission (IEC) that specifies electrical and mechanical test methods and performance limits for wrist straps and wrist strap systems. These devices are critical components in electrostatic discharge (ESD) control programs, used to prevent damage to sensitive electronic assemblies and components by ensuring proper grounding of personnel. This standard provides guidelines for the evaluation, acceptance, and periodic verification testing of wrist straps, ensuring they consistently provide reliable protection against static electricity. The 2025 edition introduces editorial improvements and updated normative references to address equipment safety.

Key Topics
Applications
IEC 61340-4-6:2025 is essential for organizations involved in the production, assembly, and maintenance of electronic devices susceptible to electrostatic discharge. Practical applications include:
- Electronics Manufacturing: Ensuring worker wrist straps meet electrical safety and mechanical durability requirements, reducing ESD-related failures in sensitive components.
- Quality Assurance: Routine in-house testing of wrist straps helps comply with industry ESD control policies and audit requirements.
- Procurement: Acceptance testing guidelines facilitate reliable sourcing of wrist straps from manufacturers, verifying product claims and marking.
- ESD Program Compliance: Enables organizations to implement structured, periodic performance checks and maintain records for auditing and certification.
- Workplace Safety: Specifications for breakaway forces and resistance values deliver added safety for personnel working around live circuits and sensitive devices.
By applying IEC 61340-4-6:2025, facilities can reliably minimize ESD risks, especially in high-reliability electronics sectors such as semiconductors, telecommunications, aerospace, and medical devices.
