ANSI C78.389 2004 Edition, 2004 For Electric Lamps - High Intensity Discharge Methods of Measuring Characteristics
More info
Description / Abstract:
Scope and purpose
This standard describes the procedures to be followed and the precautions to be observed in measuring the electrical characteristics of high intensity discharge lamps as specified in the American National Standard Specifications for Mercury (Hg), High-pressure Sodium (HPS) and Metal Halide (MH) Lamps, as referenced in clause 2, Normative references. 1
It is the purpose of this standard to outline methods of measurement that will make it possible to obtain reproducible and accurate measurements of High Intensity Discharge lamp characteristics.
Deviations from the procedures given in this standard are permissible for production or other testing, provided that the methods used give results in substantial agreement with the methods given herein. In cases of doubt, reference shall be made to the methods specified in the appropriate American National standard, referenced in clause 2, to establish the validity of the results obtained by any alternate procedure.
1 In the absence of an appropriate lamp standard, consult with particular lamp manufacturer offering the lamp in question
