Unauthorized reproduction is strictly prohibited.International Organization for StandardizationThe CANADIAN GENERAL STANDARDS BOARD (CGSB), under whose auspices this National Standard of Canada has been developed is a government agency within Public Works and Go
3、vernment 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 o
4、ther 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
5、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 as national standards, CGSB produc
6、es 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 Manual for the Development and Review of Standa
7、rds. 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 am
8、endment 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. More information is availab

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 particula
10、r 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 associated with its use. Anyone using this standard has the responsibility to consult t
11、he 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 any injury or damage that may occur during or as the result of tests, wherever perf
12、ormed. 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. Users of this standard are expressly advised that determination of the validity of a
13、ny such patent rights is entirely 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
14、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 network members, standardization is helping to advance the social and economic well-be
15、ing 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 the national economy, supporting sustainable development, benefiting the health, sa
16、fety 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 facet of the Canadian standards development system is the use of the following princ
17、iples: 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; mechanism for dispute resolution; openness and transparency; open access by intereste
18、d 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 Standard of Canada (NSC) is a standard prepared or reviewed by an SCC-accredited SDO and
19、 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 capable individuals whose collective interests provide, to the greatest practicable
20、 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 a significant and timely contribution to the Canadian interest. Those who have a n
21、eed 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 for approving standards as NSCs rests with: Standards Council of Canada 270 Albert

30、andard of CanadaThis National Standard of Canada has been prepared by the CGSB Committee on Textile Test Methods and Terminology and has been approved as a National Standard of Canada by the Standards Council of Canada. It is a modified adoption of the International Standard ISO 7211-2, Textiles Wov
31、en fabrics Construction Method of analysis Part 2: Determination of number of threads per unit length, published 1984-03-15 by the International Organization for Standardization (ISO), and is reprinted with the permission of ISO. The International Standard was reviewed by the CGSB committee to deter
32、mine its suitability for Canadian use. It was agreed to use it with the standard temperate atmosphere for conditioning. This conditioning is also described in CAN/CGSB-4.2 No. 2.A Canadian deviation has been added to 7.2, first paragraph, after the first sentence: Add “The specimens shall be cut wit
33、h the edges parallel to the warp and weft yarns.”Explanation: The National Standard of Canada modifies the requirement of the test procedure for Method A Dissection of fabric to better reflect the technical conditions used in the Canadian industry.Canadian Note: The CGSB Committee agreed that in Can
34、ada, for the purpose of this standard, the word “thread” should be interpreted as “yarn.” In this context, “yarn” and “thread” are defined as follows:Yarn A continuous strand of textile fibres that may be composed of endless filaments or shorter fibres twisted or otherwise held together. Yarns may b
35、e single or ply, and form the basic elements for cabled yarn, fabric, thread and twine.Thread The term is often applied loosely to yarn used for weaving and knitting, and is commonly used to describe fabric count as threads per unit length.Throughout this standard, the words “National Standard of Ca
36、nada” are to be understood as replacing the words “International Standard” wherever they appear.Some terminology and conventions are not identical to those used in other test methods within CAN/CGSB-4.2 Textile Test Methods. For example, the comma is used throughout this standard as a decimal marker
37、 rather than the point.The testing and evaluation of a product against this method 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 method has the responsibility to c
38、onsult 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 any injury or damage that may occur during or as the result of tests, where
