2、 ResaleNo 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 Public Works and Government Services Canada. CGSB is engaged in the production of voluntary st
3、andards 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, pr
4、ofessional 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 national standards-development organization. The standards that it dev
5、elops 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 of Canada, CGSB produces standards to meet particular needs, in response to requests fr
6、om 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 and Procedures Manual for the Development and Maintenance of Standards. CGSB standards are subject to review and
7、 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 improvement, which are always welcome, should be brought to the notice of the standards committees concerned. Chang
8、es 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, and ordering instructions, is found in the CGSB Catalogue at our Web site www.tpsgc-pwgsc.gc.ca/ ongc-cgsb along
9、 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 responsibility of the users of the standard to judge its suitability for their particular purpose. The testing and e
10、valuation 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. Anyone using this standard has the responsibility to consult the appropriate authorities a
11、nd 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 any injury or damage that may occur during or as the result of tests, wherever performed. Attention is drawn to
12、 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. Users of this standard are expressly advised that determination of the validity of any such patent rights is ent
13、irely their own responsibility. Further information on CGSB and its services and standards may be obtained from: The Manager Standards Division Canadian General Standards Board Gatineau, Canada K1A 1G6 The Standards Council of Canada (SCC) is the coordinating body of the Canadian standardization net
14、work, which is composed of people and organizations involved in the development, promotion and implementation of standards. Through the collaborative efforts of Canadian standardization network members, standardization is helping to advance the social and economic well-being of Canada and to safegua
15、rd 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 the national economy, supporting sustainable development, benefiting the health, safety and welfare of workers
16、and the public, assisting and protecting the consumer, facilitating domestic and international trade, and furthering international cooperation in relation to standardization. An important facet of the Canadian standards development system is the use of the following principles: consensus; equal acce
17、ss 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; mechanism for dispute resolution; openness and transparency; open access by interested parties to the procedures
18、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 Standard of Canada (NSC) is a standard prepared or reviewed by an SCC-accredited SDO and approved by the SCC accordi
19、ng 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 capable individuals whose collective interests provide, to the greatest practicable extent, a balance of repres
20、entation 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 a significant and timely contribution to the Canadian interest. Those who have a need to apply standards are e
21、ncouraged 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.

PURPOSE AND SCOPE1.1 This method contains five accelerated tests for determining the colourfastness to washing of t
35、extile fabrics, threadsand yarns. Each test is designed to produce in a single treatment the colour change to be expected after five averagehome or commercial washings under one of five commonly used sets of conditions.1.2 The five tests contained in this method are:1.2.1 Test No. 1 For textile mate
36、rials that are expected to withstand repeated hand washing, or equivalent gentlemachine washing at lukewarm temperatures (40 2C).1.2.2 Test No. 2 For textile materials that are expected to withstand repeated machine washing at moderatetemperatures (50 2C) in the home or in a commercial laundry.1.2.3
37、 Test No. 3 For textile materials that are expected to withstand repeated machine washing at high temperatures(70 2C) without bleach, in the home or in a commercial laundry.1.2.4 Test No. 4 For textile materials that are expected to withstand repeated machine washing at high temperatures(70 2C) in t
38、he presence of hypochlorite bleach, in the home or in a commercial laundry.1.2.5 Test No. 5 For textile materials that are expected to withstand repeated hand washing, or equivalent gentlemachine washing at cool temperatures (302C).1.3 The testing and evaluation of a product against this method may
39、require the use of materials and/or equipment thatcould be hazardous. This document does not purport to address all the safety aspects associated with its use. Anyoneusing this method has the responsibility to consult the appropriate authorities and to establish appropriate health andsafety practice
40、s in conjunction with any applicable regulatory requirements prior to its use.2. PRINCIPLE2.1 The coloured textile material and specified undyed fabric are washed together under specified conditions oftemperature, alkalinity, bleach (where required) and abrasive action. Change in colour of the test
41、specimen, andstaining of the undyed fabric, are assessed by reference to the Grey Scale.3.
