3、e CANADIAN GENERAL STANDARDS BOARD (CGSB), under whose auspices this National Standard of Canada has been developed is a government 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 o
4、f 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 testing org
5、anizations. 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 develops and offers as National Standards of Canada conform to
6、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 response to requests from a variety of sources in both the public and private sectors. Both C
7、GSB standards and CGSB national standards are developed in conformance with the policies described in the CGSB Policy Manual for the Development and Review of Standards. CGSB standards are subject to review and revision to ensure that they keep abreast of technological progress. Suggestions for thei
8、r improvement, 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 amendme
9、nts, and ordering instructions, is found in the CGSB Catalogue, which is published annually and is available without charge upon request. More information is available about CGSB products and services at our Web site www.tpsgc-pwgsc.gc.ca/ongc-cgsb. Although the intended primary application of this
10、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 evaluation of a product against this standard may require the use of materials and/or equipment that could b
11、e 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 and to establish appropriate health and safety practices in conjunction with any applicable regulatory requi
12、rements 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 the possibility that some of the elements of this Canadian standard may be the subject of patent rights. C
13、GSB 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 entirely their own responsibility.

14、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 network, which is composed of people and organizations involved in the development, promotion and implementati
15、on 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 safeguard the health and safety of Canadians. The networks efforts are overseen by SCC. The principal objectives o
16、f 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 and the public, assisting and protecting the consumer, facilitating domestic and international trade, and f
17、urthering international cooperation in relation to standardization. An important facet 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
18、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 guiding the standards development process; clarity with respect to the processes; and Canadian interest con
19、sideration 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 according to NSC approval requirements. Approval does not refer to the technical content of the standard, as this
20、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 representation of general interests, producers, regulators, users (including consumers) and others with relevant
21、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 encouraged to use NSCs. These standards are subject to periodic review. Users of NSCs are cautioned to obtai
22、n 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 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

32、4.2 No. 6-M89 ISO 7211-2:1984, IDTPreface to the National Standard 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 ado
33、ption of the International Standard ISO 7211-2, Textiles Woven 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 Intern
34、ational Standard was reviewed by the CGSB committee to determine 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, a
35、fter the first sentence: Add “The specimens shall be cut with 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 i
36、ndustry.Canadian Note: The CGSB Committee agreed that in Canada, 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 sh
37、orter fibres twisted or otherwise held together. Yarns may be 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.
38、Throughout this standard, the words “National Standard of Canada” 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, th
39、e comma is used throughout this standard as a decimal marker 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 i
40、ts use. Anyone using this method 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 any injury or d
41、amage that may occur during or as the result of tests, wherever performed.The CGSB National Standards of Canada may be obtained from the Canadian General Standards Board, Sales Centre, Gatineau, Canada K1A 1G6.
