2、ency 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 of standards committees and the consensus process. The standards committees are composed of representatives of relevant interests inclu
3、ding producers, consumers and other 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 t
4、he Standards Council of Canada 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
5、National Standards of Canada, CGSB produces 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 and Pr
6、ocedures Manual for the Development and Maintenance of Standards. CGSB standards are subject to review and 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 improveme
7、nt, 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 amendments, and or
8、dering instructions, is found in the CGSB Catalogue at our Web site www.tpsgc-pwgsc.gc.ca/ ongc-cgsb along 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 responsibi
9、lity 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 be hazardous. This document does not purport to address all the safety aspects associate
10、d 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 requirements prior to its use. CGSB neither assumes nor accepts any responsibility for any i
11、njury 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. CGSB shall not be held responsible for identifying any or all such patent rights. Users
12、of this standard are expressly advised that determination of the validity of any such patent rights is entirely their own responsibility.

13、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 implementation of standards. Through the collaborative efforts of Canadian standardization network
14、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 of SCC are to foster and promote voluntary standardization as a means of advancing the n
15、ational 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 furthering international cooperation in relation to standardization. An important facet
16、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 those who should be afforded access to provide the needed balance of interests; mechani
17、sm 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 consideration as the initial basis for the development of standards. A National Standard o
18、f 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 remains the responsibility of the SDO. An NSC reflects a consensus of a number of capab
19、le 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 interests, as may be appropriate to the subject at hand. NSCs are intended to make a si
20、gnificant 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 obtain the latest edition from the SDO that publishes the standard. The responsibility for a
21、pproving 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 819-956-5740 by mail CGSB Sales Centre Gatineau, Canada K1A 1G6 in person Place du Portage Pha

PURPOSE AND SCOPE1.1 This method is intended for the removal and quantitative determination of certain types of non-fibrous materi
32、als thatmay be present on textiles.1.2 Owing to the wide variety of substances that may be added to textile materials during manufacture, and to thedifficulty of removing some of them, this method does not provide procedures for the removal of all types of non-fibrous materials. The removal of certa
33、in finishes may require the exercise of considerable chemical resources. Ingeneral, each fabric to be analysed for content of non-fibrous materials should be considered on an individual basis.1.3 The types of fibres and the types of finishes present on a textile material will determine the procedure
34、s to be used.1.4 Although the identification of non-fibrous materials does not come within the scope of this method, reference maybe made to the bibliography given in the Notes section.1.5 The testing and evaluation of a product against this method may require the use of materials and/or equipment t
35、hatcould 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 practices in conjunction with any applicable regulatory
36、 requirements prior to its use. In general, work withsolvents should be done in an appropriate fume hood.2. PRINCIPLE2.1 The amount of non-fibrous materials, removed by the prescribed procedures, is determined on a specimen of knownmass.3. REFERENCED PUBLICATIONS3.1 The following publications are re

PROCEDURES7.1 The procedures given in par. 7.3 to 7.8 require th
47、at the specimen be oven-dried to constant mass at 105 to 110Caccording to CAN/CGSB-4.2 No. 3 (oven-dry basis) or conditioned to constant mass according to CAN/CGSB-4.2No. 2 (conditioned basis). However, when a textile contains, or is suspected of containing, low-boiling non-fibrousmaterial(s) that m
48、ay become volatile at 105 to 110C, the specimens must be conditioned, according toCAN/CGSB-4.2 No. 2, rather than oven-dried at 105 to 110C.7.2 Preliminary Determination of the Presence of Low Boiling Non-fibrous Materials7.2.1 Extract two or more 5 g specimens with solvent for 2 h in a Soxhlet extr

Transferthe solvent from the flask of the Soxhlet apparatus to a tarred weighing bottle and evaporate the solvent attemperature not over 40C until there is no appreciable mass change in 10 min. Heat the residue in an oven at 105 to110C for 30 min, cool it, and determine its mass. If there is no appreciable3loss in mass due to oven heating, lowboiling ingredients are not present in significant amounts.7.2.2 If more than one of the procedures given in par. 7.3 to 7.8 is to be used, the intermediate mass determinat
