This document briefly summarizes the following families flicker standards for information technology equipment (ITE) and related (generic) equipment:

NOTE: ??? means that no withdrawal date has been published for this standard, as of the date of this document.

DISCLAIMER
These documents are freely offered to anyone who wishes to use them. No warranty for their use is expressed or implied. The most-current versions may be downloaded from the dBi Corporation web site http://www.dbicorporation.com/. The information in these documents is believed to be correct, as far as it goes, because they are based strictly on the FCC regulations, Official Journal of the European Communities (OJ) and the test standards themselves- see Bibliography. Nevertheless, please base your decisions on the current FCC regulations, appropriate issue(s) of the OJ, the pertinent test standard(s), and their amendments.

The "References standards:" and "Referenced by standards:" sections in particular are known to be incomplete. These sections can only be filled out by referring to the exact test standard/amendment. And we don't want to spend up to several hundred dollars buying a standard to get this information, when the OJ tells us that it is identical to one we already own!

COMMENTS
If you refer to one or more of these documents in written communications, please attribute them to http://www.dbicorporation.com/. Similarly, if you link to them from your own web page(s), we would appreciate an E-mail to jrbarnes@iglou.com giving the universal resource link (URL) so that we may provide a reciprocal link.
