In 1959 it was decided to extend the work on standardization of electronic tubes and valves to reference line gauges for cathode-ray tubes. In October 1961, sheets 67-IV-1, 67-IV-2 and 67-IV-3 were adopted for inclusion in Publication 67. New developments will necessitate additions and revisions. To this end, the work is being continued.
