Values of A-C. test voltage for household devices cancelled

In the 1922 Edition of the A. I. E. E. Standards, Rule 16,000 “Values of A-C. Test Voltage for Household Devices” specifies a test of 500 volts at operating temperature for heating devices taking not over 660 watts and intended solely for operation on supply currents not exceeding 275 volts. This rule has never been replaced in the work of revision and in accordance with Standards procedure is therefore still applicable. In the opinion of the Standards Committee, because of the low value of test specified, the rule should be cancelled. An action recommending such action to the Board of Directors was taken and will come before the Board at its meeting of March 21.
