Replaced by 930-2004. This guide describes, with examples, statistical methods to analyze the data for time-to-failure from constant-stress voltage endurance tests or breakdown voltage from progressive-stress tests on specimens or systems of electrical insulation. Methods to compare test data are also given. The methods are principally applied to data from tests on solid insulation, but may also apply to the analyses of data from tests on gas, liquid, and composite systems. The statistical methods discussed here do not take into consideration the physical mechanism of voltage aging. The methods assume that the only aging stress is alternating voltage of constant frequency. The methods may not apply if there is more than one aging stress. Methods to ascertain the short time withstand voltage or operating voltage of an insulation system are not presented in this guide. The mathematical techniques contained in this guide may not directly apply to the estimation of equipment life.

Other Activities From This Working Group
Current projects that have been authorized by the IEEE SA Standards Board to develop a standard.
No Active Projects
Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.
No Active Standards
These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.
No Superseded Standards
These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.
No Inactive-Withdrawn Standards
These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.

IEEE Guide for the Statistical Analysis of Thermal Life Test Data
Statistical analyses of data from thermally accelerated aging tests are described. The basis and use of statistical calculations are explained. Data analysis, estimation of the relationship between life and temperature, and the comparison between two sets of data are covered.
1043-1996
IEEE Recommended Practice for Voltage-Endurance Testing of Form-Wound Bars and Coils
The voltage endurance testing of form-wound bars and coils for use in large rotating machines is covered.
930-2004
(Replaced) IEEE Guide for the Statistical Analysis of Electrical Insulation Breakdown Data
Replaced by IEC 62539 Ed.1 (2007-07). This guide describes, with examples, statistical methods to analyze times to breakdown and breakdown voltage data obtained from electrical testing of solid insulating materials, for purposes including characterization of the system, comparison with another insulator system, and prediction of the probability of breakdown at given times or voltages.
