The majority of the Association’s standards activities are carried out by the Technical Committee on Product Standards (TCPS) in accordance with The Aluminum Association procedures governing these activities.  Product Divisions may also form technical committees to work on specific standards that affect their products.  For example, the Electrical Division has a Task Group of AA Representatives on National Electrical Code Panels.

Builders have safely used aluminum wiring for more than 40 years.

The National Electrical Code has permitted the use of aluminum wire since 1901, a mere four years after the first recognized national electrical code was published in 1897. AA-8000 aluminum conductors have more than 40 years of reliable field installations.
