    Abstract - (Show below) - (Hide below)

    Defines the specification and test methods for unused synthetic organic esters. Pertains to synthetic organic esters, delivered to the agreed point and time of delivery intended, for use in transformers, switchgear and similar related equipment in which synthetic organic esters are required as an insulant and for heat transfer.

    Scope - (Show below) - (Hide below)

    This International Standard covers the specification and test methods for unused synthetic organic esters.

    It applies to synthetic organic esters, delivered to the agreed point and time of delivery intended, for use in transformers, switchgear and similar related equipment in which synthetic organic esters are required as an insulant and for heat transfer. These unused synthetic organic esters are obtained by chemical processing and physical treatments of fatty acids and polyols.

    NOTE Maintenance of synthetic organic esters in equipment is covered in a separate standard (IEC61203).
