39、zed labor and consumer interests, establish and improve the some 10,000 national consensus standards currently approved as American National Standards.ANSI provides that the interests of the public may have appropriate participation and representation in standardization activity, and cooperates with
40、 departments and agencies of U.S. Federal, state and local governments in achieving compatibility between government codes and standards and the voluntary standards of industry and commerce.ANSI represents the interests of the United States in international nontreaty organizations such as the Intern
41、ational Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC). The Institute maintains close ties with regional organizations such as the Pacific Area Standards Congress (PASC) and the Pan American Standards Commission (COPANT). As such, ANSI coordinates the
42、activities involved in the U.S. participation in these groups.ANSI approval of standards is intended to verify that the principles of openness and due process have been followed in the approval procedure and that a consensus of those directly and materially affected by the standards has been achieve
