22、ds 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 including manufacturers, consumer s, retailer s, unions and pro

23、fes 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, safety , building and cons truction, and the environm ent.In

24、dividuals, 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 ships. The more than 7000 committ ee volunte ers and the 2000

25、 sustai ning member ships together form CSA Gr oups total member ship fro m which its Directors are chosen. Sustai ning member ships represent a major source of income for CSA Gr oups stan dards development activities.CSA Gr oup offers certification and tes ting services in support of and as an ext

26、ension to its stan dards development activities. To ensure the integri ty of its certification pr ocess, CSA Gr oup regularly and continually audits and inspects pr oducts that bear the CSA Gr oup Mark.In addition to its head office and laboratory complex in Toronto, CSA Gr oup has regional branch o

30、andards. 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 achieving compatibility between government codes and standards

31、and the voluntary standards of indus try and commerce.ANSI represents the inter est s of the Unit ed State s in international nontreaty organizations such as the International Organization for Standardization (ISO) and the Int ernational Electr otechnical Commission (IEC). The Institut e maintains c

32、lose 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 approval of standards is intended to verify that the principl

33、es 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 te m to ensure that national standards needs are identified and
