2、o reproduction or networking permitted without license from IHS-,-,-The CANADIAN GENERAL STANDARDS BOARD (CGSB), under whose auspices this standard has been developed is a government agency within the Federal Department of Supply and Services. CGSB is engaged in the production of voluntary standards

3、 in a wide range of subject areas through the media of standards committees and the consensus process. The standards committees are composed of representatives of relevant interests including producers, consumers and other users, retailers, governments, educational institutions, technical, professio

4、nal and trade societies, and research and testing organizations. Any given standard is developed on the consensus of views expressed by such representatives. The Ministers Advisory Council on CGSB reviews the results of the consensus process. CGSB has been accredited by the Standards Council of Cana

5、da as a national standards-writing organization. The standards that it develops and offers as National Standards of Canada conform to the criteria and procedures established for this purpose by the Standards Council of Canada. In addition to standards it publishes as national standards, CGSB produce

6、s standards to meet particular needs, in response to quests from a variety of sources in both the public and private sectors. Both CGSB standards and national standards developed by CGSB are developed in conformance with the policies described in the Policy Manual for the Development and Maintenance

7、 of Standards by CGSB. CGSB standards are subject to review and revision at any time, so as to ensure that they keep abreast of technological progress. Suggestions for their improvement, which are always welcome, should be brought to the notice of the standards committees concerned. Changes to stand

8、ards are issued either as separate amendment sheets or in new editions of standards. An up-to-date listing of CGSB standards, including details on latest issues and amendments, and ordering instructions, will be found in the CGSB Catalogue, which is published annually and is available without charge

9、 upon request. 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 purpose. Many tests required by CGSB standards are inherently hazard

10、ous. CGSB neither assumes nor accepts any responsibility for any injury or damage that may occur during or as the result of tests, wherever performed. CGSB takes no position respecting the validity of any patent rights asserted with any item connected with this standard. Users of this standard are e

11、xpressly advised that determination of the validity of any such patent rights are entirely their own responsibility.

12、TANDARDS COUNCIL OF CANADA is the co-ordinating body of the National Standards System, a federation of independent, autonomous organizations workirg towards the further development and improvement of voluntary standardization in the national interest. The principal objectives of the Council are to f

13、oster 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 international trade, and furthering international co-operation in the field of standards

14、. A National Standard of Canada is a standard which has been approved by the Standards Council of Canada and one which reflecs 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

15、 of producers, users, consumers and others with relevant interests, as may be appropriate to the subject in hand. It normally is a standard that is capable of making a significant and timely contnbution to the national interest. Approval of a standard as a National Standard of Canada indicates that

16、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 accredited standards-writing organization. Those who have a need to apply standards a

17、re 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 the standard.

Flexural Strength - When tested in accordance with ASTM C 500, each 3.0 m length of pipe shall have sufficient f

39、lexural strength to withstand, without failure, the total loads specified in Table 2 when tested on a span of 2.7 m. If a length of 4.0 m is tested on a span of 3.6 m, the values of flexural strength are 75% of those listed in Table 2. TABLE 2 Flexural Strength 100 125 150 2.4 4.2 6.7 Crushing Stren

Ifthe specimens fail to withstand 75% of the load specified in Table 3, the entire lot shall be rejected. (A lot is t

41、he total length of one class and size manufactured during one shift.) When a specimen withstands over 75% but less than 100% of the specified load, one specimen shall be cut from each of two additional pipes of the same size and class manufactured during the same shift. If either of these additional

42、 specimens fails to meet the specified crushing strength requirements the entire lot of that class and size manufactured during the same shift shall be rejected as the test specimen. t I 2 CANKGSB-34.23-94 Copyright Canadian General Standards Board Provided by IHS under license with CGSBNot for Resa
