2、t 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 in a wide range of subject areas through the
3、 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, professional and trade societies; and research and tes
4、ting 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 Canada as a national standards-writing organizati
5、on. 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 produces standards to meet particular needs, in resp
6、onse to requests 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 of Standards by CGSB. CGSB standards are s
7、ubject 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 standards are issued either as separate amendmen
8、t 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 upon request. Although the intended primar
9、y 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 hazardous. CGSB neither assumes nor accepts any r
10、esponsibility 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 expressly advised that determination of the
11、validity of any such patent rights are entirely their own responsibility. Further information on CGSB and its services and standards may be obtained from: The Manager Marketing and Sales Services Canadian General Standards Board Ottawa, Canada KIA 1G6 The STANDARDS COUNCIL OF CANADA is the co-ordina
12、ting body of the National Standards System, a federation of independent, 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
13、 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 intemational trade, and furthering international co-operation in the field of standards. A National Standard of Canada is a standar
14、d 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 interests provide, to the greatest practicable extent, a balance of representation of producers, users, consumers and others
15、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 contribution to the national interest. Approval of a standard as a National Standard of Canada indicates that a standard conforms to the criteria and pr
16、ocedures 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 are encouraged to use National Standards of
17、 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.

SCOPE 1.1 This standard applies to general purpose printing bristols and to folding bristols. A standard for permanence of paper is in the course of preparation. General purp
29、ose printing bristols are used for face and back letterpress and offset (lithographic) printing of booklet covers, circulars, annoucements, programs, tickets, etc. Printed matter may include solids and solid reverses, text, line-illustrations and halftones in accordance with its specified surface ro
30、ughness and uniformity. If long-term use is a concern, the standard for permanence of paper should be used. Folding printing bristols are used for face and back letterpress and offset (lithographic) printing of booklet covers, file folders, tags, etc., requiring a high degree of durability. If long-
31、term use is a concern the standard for permanence of paper should be used. The testing and evaluation of a product against this standard may require the use of materials and/or equipment that could be hazardous. This document does not purport to address all the safety aspects associated with its use
