This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard. This Standard was prepared by the Integrated Committee on Flexible Cords/Equipment and Appliance Wires and Cables, under the jurisdiction of the Technical Committee on Wiring Products and the Strategic Steering Committee on Requirements for Electrical Safety, and has been formally approved by the Technical Committee. This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.
