Introduction
Insulating materials used in electrical and electronic equipment, it is necessary to play a considerable part of the electrically insulating effect, but also play as a heat conduction
Use, its thermal performance will directly influence the design of electrical and electronic equipment size, temperature, operational reliability and service life. However,
Standard Test Method for Determination of the relevant domestic no electrical insulating materials thermal conductivity. The development of the standard response to this situation, in order to regulate the electrical
Test Method for Thermal Conductivity of insulation.
This standard is mainly based on application status of thermal insulation materials research, as well as thermal performance testing technical level, and with reference to the United States
ASTMD5470-06 (2011) compiled.
Performance test methods for electrical insulating materials thermal conductivity
1 Scope
This standard specifies the test methods for electrical insulating materials thermal conductivity properties.
