ANSI provides a forum for development of American national standards

The American National Standards Institute - ANSI - is a private, non-profit organization that administers and coordinates the U.S. voluntary standardization and conformity assessment system.

ANSI provides a forum for development of American national standards from organizations as 

• ASME - American Society of Mechanical Engineers
• NFPA - National Fire Protection Association and more, 

and serves as a coordination point for national distribution of international standards issued from organizations as 

• ISO - International Organization for Standardization,
• DIN - Deutsches Institut für Normung eV, 
• IEC - International Electro technical Commission and others.

Many of committees are chaired and sponsored by engineering societies such as 

• ASME - American Society of Mechanical Engineers and 
• IEEE - Institute of Electrical and Electronics Engineers.

Safety is the basic objective in the standards developed by ANSI. The ANSI standards include prohibition for practices considered unsafe.

Some of the ANSI codes may eventually become known as ASME standards - as the ANSI B31 Pressure Piping Code is changed to ASME B31.
