2、e 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 in a wide range of subject areas through the media of standards committees and the consensus process. The standards commit
3、tees are composed of representatives of relevant interests including producers, consumers and other users, retailers, governments, educational institutions, technical, professional and trade societies, and research and testing organizations. Any given standard is developed on the consensus of views
4、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 Canada as a national standards-writing organization. The standards that it develops and offers as National Standards of Canada
5、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 produces standards to meet particular needs, in response to requests from a variety of sources in both the public and private sect
6、ors. 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 of Standards by CGSB. CGSB standards are subject to review and revision at any time, so as to ensure that they keep abre
7、ast of technological progress. Suggestions for their improvement, which are always welcome, should be brought to the notice of the standards committees concerned. Changes to standards are issued either as separate amendment sheets or in new editions of standards. An up-to-date listing of CGSB standa
8、rds, 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 upon request. Although the intended primary application of this standard is stated in its Scope, it is important to note
9、 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 hazardous. CGSB neither assumes nor accepts any responsibility for any injury or damage that may occur during or as the result
10、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 expressly advised that determination of the validity of any such patent rights are entirely their own responsibility. Furt

12、t, autonomous organizations working towards the further development and improvement of voluntary standardization in the national interest. The principal objectives of the Council are to foster and promote voluntary standardization as a means of advancing the national economy, benefiting the health,
13、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. A National Standard of Canada is a standard which has been approved by the Standards Council of Canada and one
14、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 appropriate to the subject in hand
15、. It normally is a standard that is capable of making a significant and timely conhibution 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 Council of Canada. Approval does
16、 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 are encouraged to use National Standards of Canada whenever practicable. These standards are subject to periodic
17、review; therefore, users are cautioned to obtain the latest edition from the organization preparing the standard.

All line posts shall be installed in a vertical position. Footing Design and Construction - The basis for any footin
43、g design shall be the National Building Code of Canada. The footing (or mechanical device embedded directly in soil) shall be capable of withstanding the specified loadings of terminal and line posts for the type of soil or rock existing at the site where the fence is to be installed.The footing mus
