Overview
EN IEC 60512-99-002:2022/A1:2025 is an amendment to the European adoption of IEC 60512 Part 99-002 and defines the endurance Test 99b: test schedule for unmating under electrical load. Approved by CENELEC in 2025, this document forms part of the IEC 60512 series on tests and measurements for connectors. It provides a standardized test schedule to assess connector behaviour when unmating occurs while current or voltage is present.
The amendment clarifies normative references and aligns the European version with the international edition. It is intended for manufacturers, test laboratories and design engineers who need to validate connector safety and durability under realistic operational stress.
Key Topics
- Scope and purpose: Establishes an endurance test schedule specifically for unmating events that occur under electrical load to evaluate performance, safety and potential failure modes.
- Standard alignment: The amendment maintains consistency with IEC 60512 and notes relevant normative references (including IEEE Std 802.3 and IEEE Std 802.3bt in the bibliography).
- Regulatory timetable: CENELEC set implementation guidance with national adoption deadlines and withdrawal schedules for conflicting national standards.
- Stakeholders: Prepared by IEC TC 48 / SC 48B (Electrical connectors) and adopted by CENELEC members across European national committees.
Applications
This test schedule has direct practical value where connectors may be disconnected while energized, including:
- Product development and validation for industrial, telecom and consumer connectors
- Quality assurance and durability testing in production and acceptance testing
- Safety and risk assessment for designs exposed to live unmating events
- Supplier and component qualification, improving interoperability and field reliability
By following a harmonized test schedule, manufacturers can reduce the risk of arcing, contact damage or unsafe conditions resulting from unmating under load and demonstrate conformity to internationally recognized testing practice.
