What does this mean?

ICC/Ansi A117.1 2003

Thanks

ICC - International Code Council

On December 9, 1994, the International Code Council (ICC) was established as a nonprofit organization dedicated to developing a single set of comprehensive and coordinated national codes.

ANSI is also a standards organization.

Is there any more information that you can supply.

Right now, based on what you have given, I can only suggest that yo are missing some letters.

It could be the "International Communication Council" or Interstate Commerce Committee or International Code Committee, but they do not set ANSI standards.

Okay,

The winner is, "ICC" = International Code Committee.

Here's the link that provides a description of the ANSI standard.
