CGSB is engaged in the product
3、ion 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 users, retailers, governments, educational institut
4、ions, 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 national standards-development organization. The st
5、andards 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 standards to meet particular needs, in response to re
6、quests 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 Standards. CGSB standards are subject to review and revision t
7、o 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 amendment sheets or in new editions of standards. An up-to
8、-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.

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 evaluation of a product again

Anyone using this standard has the responsibility to consult the appropriate authorities and to establish appropriate

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 o

14、eople 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 safeguard the health and safety of
15、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 and the public, assisting an
16、d 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 access and effective participati
17、on 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 guiding the standards develo
18、pment 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 according to NSC approval requireme
19、nts. 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 representation of general interest
20、s, 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 encouraged to use NSCs. These
21、 standards are subject to periodic review. Users of NSCs are cautioned to obtain the latest edition from the SDO that publishes the standard.

It is a modified adoption of the International Standard ISO 137, Wool Determination of fibre diameter Projection microscope method, published 1975-02-01 by the International Organization for Standar
31、dization (ISO), and is reprinted with the permission of ISO. The International 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
32、.2 No. 2.A Canadian deviation has been added to 7.1, fourth paragraph: Add “d) fibres less than 0.3 mm in length.”Explanation: The National Standard of Canada modifies the requirement of the test procedure to exclude measurement of very short fibres.Throughout this standard, the words “National Stan
33、dard 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, the comma is used throughout this standard as a deci
34、mal 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 its use. Anyone using this method has the responsib
35、ility to consult the appropriate authorities and to establish appropriate health and safety practices in conjunction with any applicable regulatory requirements prior to its use.
