A uniform method by which the thermal endurance of electrical insulation systems for dry-type specialty and general-purpose transformers can be compared is established. Covered are insulation systems intended for use in the types of transformers described in NEMA ST 1-1988 and NEMA ST 20-1992.

Standard Test Procedure for Evaluation of Systems of Insulation for Dry-Type Specialty and General-Purpose Transformers
To establish a uniform method for preparing samples, conducting tests, and analyzing results for establishing a comparative thermal life of insulation systems intended for use in dry-type transformers described in NEMA ST 1-1988 - Specialty Transformers (Except General Purpose Type) and NEMA ST 20-2014 - Dry Type Transformers for General Applications.
