Warning: Last items in stock!
Availability date:
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.
