Failure Time of PET Film

The hirose data frame has 44 rows and 3 columns.

PET film is used in electrical insulation. In this accelerated life test the failure times for 44 samples in gas insulated transformers. 4 different voltage levels were used.

Format

This data frame contains the following columns:

volt

The voltage (in kV).

time

The failure or censoring time in hours.

cens

The censoring indicator; 1 means right-censored data.
