The principal objects of the Council are to foster and promote voluntary standardization as a means of advan

A National Standard of Canada is a standard which has been ap

Approval of a standard as a National Standard of Canada indicates that a standard conforms to the criteria and procedures established by the Standards Council of C

Any divergence between the IEC Standard and the corresponding national or regional standard shall be clearly indicated in the latter. 5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment d

In excep- tional circumstances, a technical committee may propose the publication of a technical re- pori of one of the following types: type 1, when the required s

23、upport cannot be obtained for the publication of an Inter- national Standard, despite repeated efforts; type 2, when the subject is still under technical development or where for any other reason there is the future but not immediate possibility of an agreement on an Inter- na t io na I St a nda rd

24、; type 3, when a technical committee has collected data of a different kind from that which is normally published as an lnternationa! Standard, for example “state of the art“. Technical reports of types 1 and 2 are subject to review within three years of publication to decide whether they can be tra

25、nsformed into International Standards. Technical reports of type 3 do not necessarily have to be reviewed until the data they provide are considered to be no longer valid or useful.
