CSA standards reflect a national consensus of producers and users including manufacturers, consumers, retailers, unions and professional organizations, and governmental a

6、gencies. The standards are used widely by industry and commerce and often adopted by municipal, provincial, and federal governments in their regulations, particularly in the fields of health, safety, building and construction, and the environment. Individuals, companies, and associations across Cana

7、da indicate their support for CSAs standards development by volunteering their time and skills to CSA Committee work and supporting the Associations objectives through sustaining memberships. The more than 7000 committee volunteers and the 2000 sustaining memberships together form CSAs total members

8、hip from which its Directors are chosen. Sustaining memberships represent a major source of income for CSAs standards development activities. The Association offers certification and testing services in support of and as an extension to its standards development activities. To ensure the integrity o

9、f its certification process, the Association regularly and continually audits and inspects products that bear the CSA Mark. In addition to its head office and laboratory complex in Toronto, CSA has regional branch offices in major centres across Canada and inspection and testing agencies in eight co

10、untries. Since 191 9, the Association has developed the necessary expertise to meet its corporate mission: CSA is an independent service organization whose mission is to provide an open and effective forum for activities facilitating the exchange of goods and services through the use of standards, c

12、 system, a federation of independent, autonomous organizations working towards the further development and improvement of voluntary standardization in the national interest. The principal objects of the Council are to foster and promote voluntary standardization as a means of advancing the national

13、economy, benefiting the health, safety, and welfare of the public, assisting and protecting the consumer, facilitating domestic and international trade, and furthering international cooperation in the field of standards. A National Standard of Canada is a standard which has been approved by the Stan

14、dards Council of Canada and one which reflects a reasonable agreement among the views of a number of capable individuals whose collective interests provide to the greatest practicable extent a balance of representation of producers, users, consumers, and others with relevant interests, as may be app

15、ropriate to the subject in hand. It normally is a standard which is capable of making a significant and timely contribution to the national interest. Approval of a standard as a National Standard of Canada indicates that a standard conforms to the criteria and procedures established by the Standards

16、 Council of Canada. Approval does not refer to the technical content of the standard; this remains the continuing responsibility of the accredited standards-development organization. Those who have a need to apply standards are encouraged to use National Standards of Canada whenever practicable. The

17、se standards are subject to periodic review; therefore, users are cautioned to obtain the latest edition from the organization preparing the standard. The responsibility for approving National Standards of Canada rests with the Standards Council of Canada 45 OConnor Street, Suite 1 200 Ottawa, Ontar

Note: In performing this test, precautionary steps are

46、necessary to prevent a shock hazard. ) 6.6 Flexing (Power Supply Cords and Cord Sets) and Detachment6.6.1The power supply cord or cordset in a cord-connected appliance shall withstand a flexing test where thecord enters the enclosure or where the cord enters the appliance plug (or thermostatic probe

47、) withoutcausing discontinuity or exposure of a conductor or displacement or breakage of the antikink device. The rate of flexing shall be 10 cycles per minute unless the manufacturer agrees to a faster rate, and thenumber of cycles shall be as specified in Table 5. At the conclusion of the test the

48、 appliance shall still function and shall comply with the specifieddielectric strength test (see Clause 6.5). A flexing test is not required by this Standard where the cord enters the attachment plug. 6.6.2One cycle of the flexing test shall consist of the movement of the cord from one position of t

49、he mostextreme flex to the opposite position of the most extreme flex and back again, but no more than a totalof 180 (twice), and in the direction resulting in the most severe test. 6.6.3The flexing test shall be conducted with the cord under a tension of 0.12 kg (1/4 lb), with the tensionapplied to the cord 20 cm (8 in) from the point of the cord entry.
