This test method applies to the measurement of x-radiation emitted from non-raster-scanned direct-view cathode ray tubes. For some applications the test procedures described in Recommended Standard EIA-501, "Recommended Practice for the Measurement of X-Radiation from Raster-Scanned Direct-View Data Display Cathode Ray Tubes," or EIA-503, "Recommended Practice for Measurement of X-Radiation from Direct-View Television Picture Tubes, It may be more appropriately used than those described herein.

PURPOSE

The purpose of this Standard is to obtain the x-radiation characteristics of non-raster-scanned direct-view data display cathode ray tubes in order to predict the levels emitted by tubes when electrical characteristics of the application are known.
