This Standard is an adoption of the identically titled ANSI/TIA/EIA (American National Standards Institute/Telecommunications Industry Association/Electronic Industries Alliance) Standard 568-B.1-1-2001 and is the product of the Telecommunications Industry Association

6、 TR-42 Technical Committee, which included a number of Canadian members in order to ensure that Canadian perspectives and requirements were addressed. It is written in SI (metric) units with yard/pound (imperial) units in parentheses. This Standard has been adopted with no technical deviations. Wher

7、e code requirements or regulations necessitate changes from US to Canadian references, they should be made by the user, as follows: (a) Throughout this Standard, replace the term “American” with “Canadian”, as applicable. (b) Throughout this Standard, replace the term “state” with “provincial or ter

8、ritorial”, as applicable. (c) Throughout this Standard, replace “NEC” with “CE Code, Part I” (Canadian Electrical Code), as applicable. In addition, (i) where reference is made to “conduit”, replace it with “conduit/EMT” (electrical metallic tubing) because, in accordance with the Canadian Electrica

9、l Code, Part I, EMT is not considered a type of conduit; and (ii) the definitions of the following terms are to be taken from the Canadian Electrical Code, Part I: “Bonding”, “Ground”, and “Raceway”. (d) Throughout this Standard, where reference is made to “FCC”, replace it with “CRTC” (Canadian Rad
