This standard is intended to establish procedures and supervision that are required for the use and maintenance of natural ester liquid in sealed transformers and other electrical equipment.

This standard is applicable to natural esters, originally supplied conforming to IEC 62770 and other applicable Standards (e.g. ASTM D6871, etc.) in transformers, switchgear and electrical apparatus where liquid sampling is practical and where the normal operating conditions specified in the equipment specifications apply.

At present, there is a limited amount of information available for electrical equipment than transformers.

This standard is also intended to assist the power equipment operator to evaluate the condition of the natural ester and maintain it in a serviceable condition. It also provides a common basis for the preparation of more specific and complete local codes of practice. 

The standard includes recommendations on tests and evaluation procedures and outlines methods for reconditioning and reclaiming the liquid, when necessary.
