PURPOSE

This document establishes general quality criteria for
monochrome CRT bulbs. General Quality Criteria No. 1, 2, and 3 were
originally published in 1956 in JETEC Publication No. 10, which is
no longer available; they are republished in this document without
any revision or modification, because they have been incorporated
by reference in other published materials.

General Quality Criteria No. 4, while in use informally for many
years, has not previously been formally published. It was adopted
in its present form. by TEPAC in 1979 and is being formally
published at this time. General Quality Criteria No. 5 was prepared
by the JT-20 Committee and also approved for use in 1979 by TEPAC;
it is being published here for the first time.
