22、 ed by the Standards Council of Canada to the National Standards sy st em in 1973. It is a not -for - pro fit, nons tatutory , voluntary membership association engaged in stan dards development and certification activities. CSA Gr oup standards reflect a national consensus of pro ducers and user s i
23、ncluding manufacturers, consumer s, retailer s, unions and profes sional organizations, and governmental agencies. The stan dards are used widely by indus try and commerce and oft en adopt ed by municipal, provincial, and federal governments in their regulations, particularly in the fields of health
24、, safety , building and cons truction, and the environm ent.Individuals, companies, and associations acro ss Canada indicate their support for CSA Gr oups stan dards development by volunte ering their time and skills to Commit tee work and supporting CSA Gr oups objectives through sustai ning member

29、ly recognized coordinator of voluntary standards development in the United States thr ough which voluntary organizations, representing virtually every technical discipline and every facet of trade and commerce, organized labor and consumer int erests, establish and improve the some 10,000 national c
30、onsensus stan dards currently approved as American National Standards. ANSI provides that the inter ests of the public may have appr opriate participation and representation in standardization activity , and cooperate s with departments and agencies of U.S. Federal, stat e and local governments in a

32、Electr otechnical Commission (IEC). The Institut e maintains close ties with regional organizations such as the Pacific Area Standards Congress (PASC) and the Pan American Standards Commission (COPANT). As such, ANSI coordinate s the activities involved in the U.S. participation in these groups.ANSI
33、 approval of standards is intended to verify that the principles of openness and due process have been followed in the approval proce dure and that a consensus of those directly and mater ially affect ed by the stan dards has been achieved. ANSI coordination is intended to assist the voluntary sys t
