3、ment Services Canada. 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 committees are composed of representatives of relevant interests including producers, consumers and other
4、 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 expressed by such representatives. CGSB has been accredited by the Standards Council of Canada as a
5、 national standards-development 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 produces s
6、tandards to meet particular needs, in response to requests from a variety of sources in both the public and private sectors. Both CGSB standards and CGSB national standards are developed in conformance with the policies described in the CGSB Policy Manual for the Development and Maintenance of Stand
7、ards. CGSB standards are subject to review and revision 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 a
8、mendment 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, is found in the CGSB Catalogue, which is published annually and is available without charge upon request. An electronic version, ECA

22、 makes no attempt to quantify the amount of recycled fibre required in unbleached kraft wrapping paper. Provided the performance specifications are met, the paper can be made out of all-virgin fibre, ail-recycled fibre, or any combination of the two. The reason for not specifying the amount of recyc
23、led fibre in unbleached kraft wrapping paper is technical. Presently, there is no known way of measuring the amount of recycled fibre in a mixture of recycled and virgin fibres, nor does it appear likely that such a method will be developed. Purchasers who wish to specify a minimum recycled content
24、in the product will have to rely on the suppliers word regarding the percentage of recycled content. 1. 1.1 1.2 1.3 2. 2.1 2.1.1 2.1.2 2.2 SCOPE This standard states the requirements for unbleached kraft sulphate paper or other equivalent materiais made of virgin or recycled fibres. The paper in she
25、et form is intended for use in hand wrapping and the paper in roll form for hand or mechanical wrapping. The testing and evaluation of a product against this standard may require the use of materials andor equipment that could be hazardous. This document does not purport to address all safety aspect
26、s associated with its use. Anyone using this standard has the responsibility to consult the appropriate authorities and to establish appropriate health and safety practices in conjunction with any applicable regulatory requirements prior to its use.
