Heat-resistant electrical insulating materials - Part 8. fixed time method
Determine the heat insulating material index (TI and RTE)
1 Scope
This section GB/T 11026 proposes the use of a fixed time method (FTFM) of heat insulating material, temperature index (TI) and relative
Heat index (RTE) experiment and calculation procedures deduced.
According FTFM, the aging process in a handful of fixed period of time occurs each time point using the appropriate aging temperature in the corresponding
At the end of the time period, measured properties of the sample. This method GB/T 11026.1 of the procedure vary, GB/T 11026.1 aging
Process at a few fixed temperature is completed, and measuring performance according to the aging process will be carried out after the aging time.
Diagnostic tests used in FTFM limited to destructive testing. This method does not apply to non-destructive or confirmatory test.
According FTFM, this part of the experimental data obtained from TI and RTE in line with GB/T 11026.1 and IEC 60216-2, and do
Correction. The calculation procedures and statistical test is modified from the GB/T 11026.3 and IEC 60216-5 corresponding program.
