    Significance and Use

    To provide a standardized test method that can be used for a valid comparison of luminance time curves, color changes and cosmetic changes between lamps of various designs, fabrication techniques, and sources.

    1. Scope

    1.1 This test method establishes the procedures for determining the visible performance change, which is defined by luminance, color and cosmetic appearance of an electroluminescent lamp during operation over an extended time.

    1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
