The Canadian Standards Association (CSA), underwhose auspice

10、s this National Standard has been produced, was chartered in 1919 and accredited by the Standards Council of Canada to the National Standards system in 1973. It is a not-for-profit, nonstatutory, voluntary membership assodation engaged in standards development and certification activities. CSA stand

13、ns objectives through sustaining memberships. The more than 7000 committeevolunteers and the 2000 sustaining memberships together form CSAs total membership from which its Directors are chosen. Sustaining memberships represent a major source of income for CSAs standards development activities. The A

14、ssociation offers certification and testing services in support of and as an extension to its standards development actMties. To ensure the integrity of its certification process, the Assodation reguIa1y and continually audits and inspects products that bear the CSA Mark. In addition to its head off
