Comparison of ASTM D971 and IEC 62961 standards

This webinar provides an overview of the key differences between the new IEC 62961 and the older ASTM D971 standards for measuring the quality of insulating oils used in electrical transducers. It highlights why the IEC 62961 standard was introduced, the main procedural changes, and the improvements it brings, such as updated measurement timing, relaxed water purity requirements, encouragement of automation, and enhanced cleaning protocols. The session is concise, lasting about 10 minutes, and is designed to help participants understand what has changed and why these changes matter
