Anotace textu normy ČSN EN IEC 63013 (360701):

This document is applicable to LED packages for general lighting services.
It specifies procedures and conditions for measuring the luminous flux maintenance of LED packages. It also provides the procedures and conditions (criteria) of projecting the long-term luminous flux maintenance based on limited luminous flux maintenance test data collected. Within the context of this document, wherever luminous flux measurement data is specified, radiant flux measurement data can also be used.
These projection methods employ data collected as per ANSI/IES LM-80-15 (LM-80).
The long-term projection is based on the exponential-fit-function procedure of IES TM-21-11 (TM-21), and gives an alternative border function procedure in the case where the exponential-fit-function of IES TM-21-11 is not applicable.
