Summary: This standard specifies the low voltage motor stator winding insulation life assessment of rapid test methods. The method uses the machine for sample temperature stepwise manner to achieve rapid test purposes, the average life expectancy of the insulation structure to obtain maximum likelihood estimates. This standard applies to run under normal conditions, a variety of heat-resistant grade of three-phase, single-phase low voltage motors, its life lognormal distribution, pending flat insulation insulation structure and benchmarks compared in the same experiment to assess the relative.
