2、t agency within Public Works and Government 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 i

3、ncluding 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 expressed by such representatives. CGSB has been accredited

4、by the Standards Council of Canada as a 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

5、 as National Standards of Canada, CGSB produces standards 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 an

6、d Procedures Manual for the Development and Maintenance of Standards. CGSB standards are subject to review and revision to ensure that they keep abreast of technological progress. CGSB will initiate the review of this standard within five years of the date of publication. Suggestions for their impro

7、vement, 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 standards, including details on latest issues and amendments, an

8、d ordering instructions, is found in the CGSB Catalogue at our Web site www.tpsgc-pwgsc.gc.ca/ ongc-cgsb along with more information about CGSB products and services. Although the intended primary application of this standard is stated in its Scope, it is important to note that it remains the respon

9、sibility of the users of the standard to judge its suitability for their particular purpose. 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 assoc

10、iated 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. CGSB neither assumes nor accepts any responsibility for a

11、ny injury or damage that may occur during or as the result of tests, wherever performed. Attention is drawn to the possibility that some of the elements of this Canadian standard may be the subject of patent rights. CGSB shall not be held responsible for identifying any or all such patent rights. Us

12、ers of this standard are expressly advised that determination of the validity of any such patent rights is entirely their own responsibility.

13、ada K1A 1G6 The Standards Council of Canada (SCC) is the coordinating body of the Canadian standardization network, which is composed of people and organizations involved in the development, promotion and implementation of standards. Through the collaborative efforts of Canadian standardization netw

14、ork members, standardization is helping to advance the social and economic well-being of Canada and to safeguard the health and safety of Canadians. The networks efforts are overseen by SCC. The principal objectives of SCC are to foster and promote voluntary standardization as a means of advancing t

15、he national economy, supporting sustainable development, benefiting the health, safety and welfare of workers and the public, assisting and protecting the consumer, facilitating domestic and international trade, and furthering international cooperation in relation to standardization. An important fa

16、cet of the Canadian standards development system is the use of the following principles: consensus; equal access and effective participation by concerned interests; respect for diverse interests and identification of those who should be afforded access to provide the needed balance of interests; mec

17、hanism for dispute resolution; openness and transparency; open access by interested parties to the procedures guiding the standards development process; clarity with respect to the processes; and Canadian interest consideration as the initial basis for the development of standards. A National Standa

18、rd of Canada (NSC) is a standard prepared or reviewed by an SCC-accredited SDO and approved by the SCC according to NSC approval requirements. Approval does not refer to the technical content of the standard, as this remains the responsibility of the SDO. An NSC reflects a consensus of a number of c

19、apable individuals whose collective interests provide, to the greatest practicable extent, a balance of representation of general interests, producers, regulators, users (including consumers) and others with relevant interests, as may be appropriate to the subject at hand. NSCs are intended to make

20、a significant and timely contribution to the Canadian interest. Those who have a need to apply standards are encouraged to use NSCs. These standards are subject to periodic review. Users of NSCs are cautioned to obtain the latest edition from the SDO that publishes the standard. The responsibility f

21、or approving standards as NSCs rests with: Standards Council of Canada 270 Albert Street, Suite 200 Ottawa, Ontario K1P 6N7, CANADA How to order Publications: by telephone 819-956-0425 or 1-800-665-2472 by fax 819-956-5740 by mail CGSB Sales Centre Gatineau, Canada K1A 1G6 in person Place du Portage

TEST SPECIMENS5.1 If the textile to be tested is fabric, two specimens not less than 50 150 mm shall be taken for dry rubbing and twofor each type of wet rubbing. One sp

45、ecimen of each pair shall be cut lengthwise of the fabric and the othercrosswise. Insofar as possible, the specimens shall be representative of all colours of multicolour fabric.5.2 If the textile to be tested is a yarn or thread, it shall be knitted into cloth of suitable dimensions (par. 5.1) or a

46、 layerof parallel strands shall be formed by wrapping it lengthwise on a cardboard rectangle of suitable dimensions.5.3 If the textile to be tested is in the form of loose fibres, a test specimen shall be prepared by laying tufts of fibresparallel to the long dimension of the specimen to make a pad

47、50 150 mm and 10 mm thick in the uncompressedstate. The pad shall then be compressed and sewn with undyed cotton thread to a piece of undyed cotton fabric, withthe seams parallel to the short dimension of the specimen and spaced approximately 20 mm apart.6. PROCEDURE6.1 For Dry Rubbing Condition the

48、 specimens and the bleached undyed cloth in accordance with CAN/CGSB-4.2No. 2. Place the test specimen in position on the abrasive paper surface with the face of the fabric up, unless1For use in the testing of yarns and thread, a yarn testing finger is available from R.B.
