Full title and description
Electrical insulating materials and systems — General method of evaluation of electrical endurance under repetitive voltage impulses. IEC 62068:2013 defines test procedures to screen and comparatively evaluate the endurance of electrical insulating materials (EIM) and electrical insulation systems (EIS) when subjected to repetitive impulse voltages, with emphasis on equipment connected to electronic power supplies.
Abstract
IEC 62068:2013 provides a general method for assessing the electrical endurance of insulating materials and systems under conditions of repetitive voltage impulses. It specifies screening and endurance test methods, impulse‑voltage characteristics, partial discharge measurement concepts (including RPDIV and RPDEV), and guidance on data processing and statistical evaluation to enable relative comparison of insulation endurance. The edition replaces IEC 62068-1:2003 and aligns terminology with related IEC technical specifications.

Scope
This standard applies to electrical equipment, irrespective of voltage, that contains an insulation system which is connected to an electronic power supply and requires evaluation of insulation endurance under repetitive voltage impulses. It provides a general test procedure intended to facilitate screening of EIM and EIS and to obtain a relative evaluation of insulation endurance when exposed to periodic impulse stresses.
Key topics and requirements
- Definitions and terminology aligned with IEC/TS 61934 and IEC/TS 60034-18-42 for consistency across insulation evaluation documents.
- Two principal test approaches: a screening (comparative) test method and an endurance test method using a reference EIS.
- Specification of impulse-voltage characteristics (polarity, rise/decay time, repetition rate, duty cycle) used for testing.
- Partial discharge considerations and measurement metrics including repetitive partial discharge inception voltage (RPDIV) and repetitive partial discharge extinction voltage (RPDEV).
- Requirements for test object selection, conditioning and instrumentation for meaningful comparative results.
- Data processing and statistical treatment guidance (references IEC 62539) for analysis of breakdown and life data.
- Evaluation and reporting rules to permit relative ranking of EIM/EIS performance under repetitive impulse stress.
Typical use and users
Used by manufacturers of electrical equipment (motors, transformers, power converters, electronic power supplies), insulation material developers, test laboratories, certification bodies and R&D teams. Typical applications include materials screening during development, comparative life-assessment of insulation systems, qualification testing for products exposed to switching/impulse stresses, and research into partial-discharge susceptibility under repetitive impulses.
