3、DIAN GENERAL STANDARDS BOARD (CGSB), under whose auspices this standard has been developed is a government agency within the Federal Department of Supply and Services. CGSB is engaged in the production of voluntary standards in a wide range of subject areas through the media of standards commitiees

4、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 organizations. Any given s

5、tandard is developed on the consensus of views expressed by such representatives. The Ministers Advisory Council on CGSB reviews the results of the consensus process. CGSB has been accredited by the Standards Council of Canada as a national standards-writing organization. The standards that it devel

6、ops 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 requests from a variety

7、 of sources in both the public and private sectors. Both CGSB standards and national standards developed by CGSB are developed in conformance with the policies described in the Policy Manual for the Development and Maintenance of Standards by CGSB. CGSB standards are subject to review and revision a

8、t any time, so as 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 amendment sheets or in new editions of

9、standards. An up-to-date listing of CGSB standards, including details on latest issues and amendments, and ordering instructions, will be found in the CGSB Catalogue, which is published annually and is available without charge upon request. Although the intended primary application of this standard

10、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. Many tests required by CGSB standards are inherently hazardous. CGSB neither assumes nor accepts any responsibility for any injq or d

11、amage that may occur during or as the result of tests, wherever performed. CGSB takes no position respecting the validity of any patent rights asserted with any item connected with this standard. Users of this standard are expressly advised that determination of the validity of any such patent right

12、s are entirely their own responsibility. Further information on CGSB and its services and standards may be obtained from: The Secretary Canadian General Standards Board Ottawa, Canada K1A 1G6 The STANDARDS COUNCIL OF CANADA is the coordinating body of the National Standards System, a federation of i

13、ndependent, autonomous organizations working towards the further development and improvement of voluntary standardization in the national interest. The principal objectives of the Council are to foster and promote voluntary standardization as a means of advancing the national economy, benefiting the

14、 health, safety and welfare of the public, assisting and protecting the consumer, facilitating domestic and international trade, and furihering international co-operation in the field of standards. A National Standard of Canada is a standard which has been approved by the Standards Council of Canada

15、 and one which reflects a reasonable agreement among the views of a number of capable individuals whose collective interests provide, to the greatest practicable extent, a balance of representation of producers, users, consumers and others with relevant interests, as may be appropriate to the subjec

16、t in hand. It normally is a standard that is capable of making a significant and timely contribution to the national interest Approval of a standard as a National Standard of Canada indicates that a standard conforms to the criteria and procedures established by the Standards Council of Canada. Appr

17、oval does not refer to the technical content of the standard; this remains the continuing responsibility of the accredited standards-writing organization. Those who have a need to apply standards are encouraged to use National Standards of Canada whenever practicable. These standards are subject to

18、periodic review; therefore, users are cautioned to obtain the latest edition from the organization preparing the standard.

The intemational standard was reviewed by the CGSB committee to determine its suitability for Canadian use. It was agreed to use it in total, without editorial changes. Throughout this standard, the

31、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 CANKGSB-4.2-M - Textile Test Methods. For example, the comma is used throughout

32、 this standard as a decimal marker rather than the point. The following National Standards of Canada correspond to the referenced IS0 standards: CANADA IS0 - CAN/CGSB-4.175-M Part 2DSO 6348 IS0 6348 CAN/CGSB-4.2 NO. 72.1-M/ISO 6741-1 CAN/CGSB-4.2 NO. 72.2-M/ISO 6741-2 IS0 6741 Part 1 IS0 6741 Part 2

37、O Introduction This document forms part 3 of a four-part International Stan- dard prepared by ISO/TC 38, Textiles. Part 1 : Mass determination and calculations. Part 2 : Methods for obtaining laboratory samples. Part 3: Specimen cleaning procedures. Part 4: Values used for the commercial allowances

38、and the commercial moisture regains. (Technical Report.) The terminology used in this International Standard is in ac- cordance with IS0 6348. Most contracts of sale between buyer and seller specify either that the invoice mass of a consignment shall be determined by an independent third party, or t

39、hat the sellers figure may be subject to an independent third-party check. This part of IS0 6741 describes the methods which are to be used by the in- dependent third patty in these cases. The figure for the com- mercial mass which results from the application of the pro- cedures in this part of IS0

40、 0141 either becomes the invoice mass of the consignment or is compared with the declared in- voice mass plus or minus the tolerance agreed behiveen the buyer and seller. It is not intended that the methods in this part of IS0 6741 necessarily be used by the seller to establish his invoice mass. The

41、 methods described in this part of IS0 6741 are, for the most part, destructive. 1 This part of IS0 741 specifies specimen cleaning procedures to be used when the commercial mass is to be determined in accordance with IS0 6741-1 on a clean and dry basis. The pro- cedure appropriate for a particular

42、fibre is given in IS0 67414. If the commercial mass is to be determined on a dry-only basis, cleaning is omitted.
