IEEE Standard for the Preparation of Test Procedures for the Thermal Evaluation of Solid Electrical Insulating Materials
Revision Standard - Active.
The test procedures covered by this standard apply to the thermal endurance of solid insulating materials, including processed compositions of raw materials, before they are fabricated into insulating structures identified with specific parts of electrical equipment.
The test procedures covered by this standard apply to the thermal endurance of solid insulating materials, including processed compositions of raw materials, before they are fabricated into insulating structures identified with specific parts of electrical equipment.
Tests for specific types of insulating materials, such as wire enamel, varnish, sheet, tape, etc., are not within the scope of this standard.
This standard provides principles for the development of test procedures to evaluate the thermal endurance of solid electrical insulating materials (EIMs) thermally aged in air.
The test procedures use accelerated thermal endurance test(s), conducted in accordance with prescribed procedures herein.
The thermal endurance value for a measured property can be assigned based on one of two following methodologies:
Both TI and RTI are long-term thermal aging (LTTA) methodologies.
