Overview
IEC 62911:2025 - "Audio, video and information technology equipment - Routine electrical safety testing in production" specifies routine electrical safety test procedures to be used during or after manufacturing of complete equipment, sub-assemblies or components powered from AC or DC mains. The standard is intended to detect manufacturing failures and unacceptable tolerances in materials and assembly for equipment that complies with IEC 62368-1 (and legacy IEC 60065 / IEC 60950-1). IEC 62911:2025 emphasizes production-level testing (not product development or type verification) and aligns terminology and requirements with IEC 62368-1:2023.
Key topics and requirements
- Scope and purpose: Defines routine electrical safety tests (3.16) for each manufactured item to identify production/manufacturing errors.
- Test types: Includes continuity/ resistance testing of the protective bonding system (for Class I equipment) and electric strength (dielectric) tests.
- AC and DC mains: Adds explicit test conditions for equipment supplied from DC mains in addition to AC mains. Test voltage tables are provided for different mains/overvoltage categories.
- Conformance and records: Equipment must pass applicable routine tests before shipment; results shall be recorded per Clause 6.
- Practical guidance: Notes state that not all routine tests must be performed at the final assembly site - manufacturers can define optimal test location and integrate with the applicable conformity assessment scheme.
- Limitations: Tests are intended to find manufacturing faults and are not a substitute for type testing or design verification (see IEC 62368-1).
Practical applications and users
Who uses IEC 62911:2025:
- Manufacturers and contract assemblers - to define and implement production-line electrical safety checks.
- Production test engineers / QA teams - to set up continuity, dielectric and bonding tests and to maintain test records.
- Test lab personnel and conformity assessors - to review production test plans as part of certification and conformity schemes.
- Safety managers and compliance officers - to ensure routine testing aligns with IEC 62368-1 safety objectives.
Practical uses:
- Preventing shipping of units with assembly defects (e.g., improper earth bonding, insulation faults).
- Integrating routine tests into automated production test stations.
- Demonstrating ongoing compliance during audits via documented test records.
