CGSB is engaged in the production of voluntary stan
3、dards in a wide range of subject areas through the niedia of standards committees and the consensus process. The standards committees are composed of represcntatives of relevant interests including producers, consumers and other users, retailers, governments, educational institutions, technical, pro
4、fessional and trade societies, and research and testing organizations. Any given standard 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 o
5、f Canada as a national standards-writing 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 p
6、roduces 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 national standards developed by CGSB are developed in conformance with the policies described in the Policy Manual for the Development and Mai
7、ntenance of Standards by CGSB. CCSB standards are subject to review and revision at 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
8、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 ordering instructions, will be found in the CGSB Catalogue, which is published annually and is available withou
9、t 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. Many tests required by CGSB standards are inherentl
10、y hazardous. CCSB neither assumes nor accepts any responsibility for any injury or damage 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 standa

12、Canada KIA 1G6 O The STANDARDS COUNCIL OF CANADA is the co-ordinating body of the National Standards System, a federation of independent, autonomous organizations working towards the further development and improvement of voluntary 4 standardization in the national interest. The principal objectives
13、 of the Council are to foster and promote voluntary standardization as a means of advancing the national economy, benefiting the health, safety and welfare of the public, assisting and protecting the consumer, facilitating domestic and international trade, and furthering international co-operation i
14、n the field of standards. A National Standard of Canada is a standard which has been approved by the Standards Council of Canada 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
15、balance of representation of producers, users, consumers and others with relevant interests, as may be appropriate to the subject 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
16、 of Canada indicates that a standard conforms to the criteria and procedures established by the Standards Council of Canada. Approval 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
17、 need to apply standards are encouraged to use National Standards of Canada whenever practicable. These standards are subject to periodic review; therefore, users are cautioned to obtain the latest edition from the organization preparing the standard. The responsibility for approving National Standa

PREPARATION FOR DELIVERY 6.1 Knos - There shall not be more than one finished thread-knot per loo0 m. Packaging, Labelling, Packing and Marking - Unless otherwise specified (par. ticket no. R 180 tex - 5
36、0 g). Measure and record the length of the loop to the nearest millimetre. Remove the weight and lay the specimen flat and unrestrained in the beaker. Add 250 mL of O. 1% soap solution (1 g of soap per litre of distilled water), raise the solution to loOC and boil gently for 1Omin. Remove the specim
37、en, hang it vertically without tension from horizontal pin and allow it to dry at room temperature for 24 h. Remeasure the specimen under the appropriate tension (as previously specified). Calculate the percent shrinkage to the nearest 0.1%. Average the results of the six specimens. Care should be t
38、aken to ensure that twist is not affected during the test.

Grey Scale for assessing staining (CANKGSB4.2 No. 47/iSO 10YA03). 7.3.2.2 Test Specimen - The thread shaU be formed into a 1 g skein
40、of suitable size and placed between the two pieces of mult5bre fabric, in contact with the bands of the test fabric, to form a composite specimen. Condition the specimen in accordance with CANEGSB4.2 No. 2. 7.3.2.3 Procedure - Place the composite specimen in the Scorch Tester for 30 s at 175 f 2OC (
41、par. 7.3.2.4). Apply sufficient pressure to the composite test spechen to assure intimate contact between the test specimen and the plates of the tester. (Minor variations in pressure do not afa the result.) Remove the composite specimen from the tester and separate the components for evaluation. Me
42、asure and report the colour change of the test specimen using CANICGSB-42 No. 4iSO 105/A02: a after 1 min, and b. after conditioning (CANKGSB4.2 No. 2). Measure and report the staining of each kind of fibre in the multifiber test cloth using CANKGSB-4.2 No. 47/ IS0 1051A03. 7.3.2.4 The accuracy of t
43、his test is dependent upon the uniformity of the heat supplied by the Scorch Tester and upon the temperature of the thread. It is suggested that the thread temperature be measured with a thermocouple or thermopaper placed between the specimen being tested and the mulWibre test fabric. It is desirabl
44、e to caiibrate the instrument periodically to ensure its accuracy. Although a thermocouple is preferable for measuring the temperature, themostat paper (Note 4) wiii give quite an accunite measurement of temperatwe. 7.3.3 Static WrtcrAbsorption Test 7.3.3.1 Apparatus and Materidi Wringer - A househo
