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 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

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.

Calculate the percent shrinkage to the nearest 0.1%. Average the results of the six specimens. Care should be t

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.

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
