Abstract
It is first pointed out that triodes are life tested primarily as an aid to the manufacturers in proving their performance and useful length of service rather than to obtain any average life figure. The apparatus employed and its method of operation, together with the procedure in handling the data, is next described. Some actual results obtained are then given to illustrate the methods employed and results obtained. These results are given in the form of tables and curves. One point emphasized thruout the paper is that triode life is just as much a variable as other factors such as electron emission or impedance.
