scope:

This test method applies to the measurement of x-radiation emitted from projection cathode-ray tubes.

For some applications the test procedures described in Recommended Standard EIA-503 "Recommended Practice for Measurement of X-Radiation from Direct-View Television Picture Tubes," may be more appropriately used than those described herein.

PURPOSE

The purpose of this Standard is to obtain the x-radiation characteristics of projection cathode-ray tubes in order to predict the levels emitted by tubes when the electrical characteristics of the application are known.
