Blank pageCAN/CSA-C22.2 No. 126.2-02A National Standard of Canada(approved January 2005)Nonmetallic Cable Tray Systems The Canadian Standards Association (CSA), under whose ausp
5、ices 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 association engaged in standards development and certification activities. CSA s
6、tandards reflect a national consensus of producers and users including manufacturers, consumers, retailers, unions and professional organizations, and governmental agencies. The standards are used widely by industry and commerce and often adopted by municipal, provincial, and federal governments in
7、their regulations, particularly in the fields of health, safety, building and construction, and the environment. Individuals, companies, and associations across Canada indicate their support for CSAs standards development by volunteering their time and skills to CSA Committee work and supporting the
8、 Associations objectives through sustaining memberships. The more than 7000 committee volunteers 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 activ
9、ities. The Association offers certification and testing services in support of and as an extension to its standards development activities. To ensure the integrity of its certification process, the Association regularly and continually audits and inspects products that bear the CSA Mark. In addition
10、 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 countries. Since 1919, the Association has developed the necessary expertise to meet its corporate mission: CSA is an independent service
11、 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, certification and related services to meet national and international needs.For further information on CSA services, write toCanadian Sta
12、ndards Association5060 Spectrum Way, Suite 100Mississauga, Ontario, L4W 5N6CanadaThe Standards Council of Canada is the coordinating body of the National Standards system, a federation of independent, autonomous organizations working towards the further development and improvement of voluntary stand
13、ardization in the national interest. The principal objects of the Council are to foster and promote voluntary standardization as a means of advancing the national economy, benefiting the health, safety, and welfare of the public, assisting and protecting the consumer, facilitating domestic and inter
14、national trade, and furthering international cooperation in the field of standards. A National Standard of Canada is a standard which has been approved by the Standards Council of Canada and one which reflects a reasonable agreement among the views of a number of capable individuals whose collective
15、 interests provide to the greatest practicable extent a balance of representation of producers, users, consumers, and others with relevant interests, as may be appropriate to the subject in hand. It normally is a standard which is capable of making a significant and timely contribution to the nation
16、al 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 Council of Canada. Approval does not refer to the technical content of the standard; this remains the continuing responsibility of the a
17、ccredited standards development organization. Those who have a need to apply standards are encouraged to use National Standards of Canada whenever practicable. These standards are subject to periodic review; therefore, users are cautioned to obtain the latest edition from the organization preparing
18、the standard.The responsibility for approving National Standards of Canada rests with theStandards Council of Canada270 Albert Street, Suite 200Ottawa, Ontario, K1P 6N7CanadaCette Norme nationale du Canada est offerte en anglais et en franais.Although the intended primary application of this Standar

26、le Tray Systems. It is the first edition of CSA C22.2 No. 126.2 and the first edition of UL 568. This common standard was prepared by the CANENA Technical Harmonization Committee for Nonmetallic Cable Tray Systems, which comprises members from Underwriters Laboratories, the Canadian Standards Associ
27、ation, and the cable tray manufacturing industry. The efforts of the CANENA Technical Harmonization Committee are gratefully acknowledged. This standard was reviewed by the CSA Subcommittee on C22.2 No. 126, under the jurisdiction of the Technical Committee on Wiring Products and the Strategic Resou
28、rce Group, and has been formally approved by the Technical Committee. The requirements of CSA Standard C22.2 No. 126, published in 1991, are superseded by this standard for products covered in this standard as indicated in the scope of this standard. Where reference is made to a specific number of s
29、amples to be tested, the specified number is considered to be a minimum quantity. This standard has been approved by the American National Standards Institute (ANSI) as an American National Standard. The most recent designation of ANSI/UL 568 as an American National Standard occurred on July 30, 200
30、4. This ANSI/UL Standard for Safety, which consists of the first edition, is under continuous maintenance, whereby each revision is ANSI approved upon publication. Comments or proposals for revisions on any part of the standard may be submitted to UL at any time. Written comments are to be sent to t
31、he UL-SC Standards Department, 1655 Scott Blvd., Santa Clara, CA 95050. Note: Although the intended primary application of this standard is stated in its scope, it is important to note that it remains the responsibility of the users of the standard to judge its suitability for their particular purpo
32、se. Level of Harmonization This standard uses an IEC format, but is not based on, nor is it to be considered equivalent to, an IEC standard. This standard is published as an equivalent standard for CSA and UL. An equivalent standard is a standard that is substantially the same in technical content,
33、except as follows. Technical deviations are allowed for codes and governmental regulations and those recognized as being in accordance with NAFTA Article 905, for example, because of fundamental, climatic, geographical, technological, or infrastructural factors, scientific justification, or the leve
34、l of protection that the country considers appropriate. Presentation is to be word for word except for editorial changes. Reasons for Differences to IEC The Technical Harmonization Committee identified one IEC Standard that addresses electrical cable tray systems included in the scope of this standa
35、rd. The THC determined that the safe use of electrical cable tray is dependent on the design, performance, and installation of the cable tray system. Significant investigation is required to assess safety and system issues that may lead to harmonization of traditional North American electrical cable
36、 tray standards with those presently addressed in the known IEC standard. The THC agreed such future investigation might be facilitated by completion of harmonization of the North American standards for electrical cable tray. JANUARY 28, 2005 CSA C22.2 NO. 126.2-02 UL 568 5 Interpretations The inter
37、pretation by the Standards Development Organization (SDO) of an identical or equivalent standard is to be based on the literal text to determine compliance with the standard in accordance with the procedural rules of the SDO. If more than one interpretation of the literal text has been identified, a
38、 revision is to be proposed as soon as possible to each of the SDOs to more accurately reflect the intent. UL Effective Date As of October 15, 2004, all products Listed or Recognized by UL must comply with the requirements in this standard. CSA Effective Date The effective date for CSA will be annou
39、nced through CSA Informs or a CSA Certification Notice. 6 CSA C22.2 NO. 126.2-02 UL 568 OCTOBER 15, 2002 Foreword (CSA) The Canadian Standards Association (CSA) develops standards under the name Canadian Standards Association, and provides certification and testing under the name CSA International.
40、CSA International provides certification services for manufacturers who, under license from CSA, wish to use the appropriate registered CSA Marks on certain products of their manufacture to indicate conformity with CSA Standards. CSA Certification for a number of products is provided in the interest
41、 of maintaining agreed-upon standards of quality, performance, interchangeability and/or safety, as appropriate. Where applicable, certification may form the basis for acceptance by inspection authorities responsible for enforcement of regulations. Where feasible, programs will be developed for addi
42、tional products for which certification is desired by producers, consumers, or other interests. In performing its functions in accordance with its objectives, CSA does not assume or undertake to discharge any responsibility of the manufacturer or any other party. The opinions and findings of the Ass
43、ociation represent its professional judgement given with due consideration to the necessary limitations of practical operation and state of the art at the time the Standard is processed. Products in substantial accord with this Standard but which exhibit a minor difference or a new feature may be de
44、emed to meet the Standard providing the feature or difference is found acceptable utilizing appropriate CSA International Operating Procedures. Products that comply with this Standard shall not be certified if they are found to have additional features which are inconsistent with the intent of this
45、Standard. Products shall not be certifiable if they are discovered to contravene applicable laws or regulations. Testing techniques, test procedures, and instrumentation frequently must be prescribed by CSA International in addition to the technical requirements contained in Standards of CSA. In add
46、ition to markings specified in the Standard, CSA International may require special cautions, markings, and instructions that are not specified by the Standard. Some tests required by CSA Standards may be inherently hazardous. The Association neither assumes nor accepts any responsibility for any inj
47、ury or damage that may occur during or as the result of tests, wherever performed, whether performed in whole or in part by the manufacturer or the Association, and whether or not any equipment, facility, or personnel for or in connection with the test is furnished by the manufacturer or the Associa
48、tion. Manufacturers should note that, in the event of the failure of CSA International to resolve an issue arising from the interpretation of requirements, there is an appeal procedure: the complainant should submit the matter, in writing, to the Secretary of the Canadian Standards Association. If t
49、his Standard is to be used in obtaining CSA Certification please remember, when making application for certification, to request all current Amendments, Bulletins, Notices, and Technical Information Letters that may be applicable and for which there may be a nominal charge. For such information or for further information concerning CSA Certification, please address your inquiry to Applications and Customer Service, CSA International, 178 Rexdale Boulevard, Toronto, Ontario, Canada M9W 1R3.
