3、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 committees and the consensus process. The standards committe
4、es 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 standard is developed on the consensus of views ex
5、pressed 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 develops and offers as National Standards of Canada co
6、nform 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 of sources in both the public and private sector
7、s. 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 at any time, so as to ensure that they keep abreas
8、t 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-date listing of CGSB standard
9、s, 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 is stated in its Scope, it is important to note t
10、hat 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 injury or damage that may occur during or as the result of
11、 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 rights are entirely their own responsibility. Furthe
12、r information on CGSB and its services and standards may be obtained from: The Secretary Canadian General Standards Board Ottawa, Canada KIA 1G6 The STANDARDS COUNCIL OF CANADA is the co-ordinating body of the National Standards System, a federation of independent, autonomous organizations working t
13、owards 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 health, safety and welfare of the public, ass
14、isting and protecting the consumer, facilitating domestic and international trade, and furthering 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 and one which reflects a reasonable agreement
15、 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 subject in hand. It normally is a standard that is c
16、apable of making a significant and timely conribution 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. Approval does not refer to the technical content o
17、f 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 periodic review; therefore, users are cautione
18、d to obtain the latest edition from the organization preparing the standard.

It is ide
29、ntical in content and in layout with International Standard IS0 2551, Machine-made textile floor coverings - Determination of dimensional changes due to the effects of varied water and heat conditions, published 1981-12-01 by the International Organization for Standardization (ISO). The Internationa
30、l 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 words “National Standard of Canada” are to be understood as replacing the words “International Standard” wherever th
31、ey appear. Some terminology and conventions are not identical to those used in other test methods within CANKGSB-4.2 - Textile Test Methods. For example, the comma is used throughout this standard as a decimal marker rather than the point. Throughout the standards, for the word “cockling” read the m
32、ore common Canadian word “buckling andior rucking.” There is no National Standard of Canada corresponding to the referenced IS0 1957 standard. The testing and evaluation of a product against this method may require the use of materiais and/or equipment that could be hazardous. This document does not
33、 purport to address ail the safety aspects associated with its use. Anyone using this method has the responsibility to consult the appropriate authorities and to establish appropriate health and safety practices in conjunction with any existing applicable regulatory requirerncnts prior to its use.

36、INTERNATIONAL STANDARD IS0 2551-1981 (E) Machine-made textile floor coverings - Determination of dimensional changes due to the effects of varied water and heat conditions 1 Scope and field of application This International Standard specifies a procedure for the deter- mination of the dimensional ch
37、anges that take place when machine-made textile floor coverings are subjected to varied water and heat conditions. The method is applicable to all machine-made textile floor coverings. 2 Reference IS0 1957, Machine-made textile floor coverings - Sampkng and cutring specimens for physical tests. 3 Pr
38、inciple Comparison is made between dimensions of a test specimen after conditioning in the standard atmosphere for testing tex- tiles and then after being subjected to specified varied water and heat conditions. 4 Apparatus 4.1 Instrument capable of measuring length to the nearest 0,05 mm; for examp
39、le, optical bench or mechanical device with gauge. 4.2 Plate glass sheet, marginally smaller than the test specimen, or other means of keeping the specimen flat while measurements are made. This will not be required if the instru- ment in 4.1 incorporates such a glass or metal plate. 4.3 Ventilated
40、drying oven, capable of being controlled at 60 ? 2 OC, with perforated and lacquered shelves that can be placed in the oven. 4.4 reference points on the test specimen, if necessary. Steel pins, or other appropriate means of indicating the 4.5 Enclosure, to provide the standard atmosphere for testing
41、 textiles. 4.6 Container, to hold water at 20 k 2 OC, of dimensions at least 20 mm greater than the test specimen and deep enough to accommodate the submerged test specimen. 5 Test specimen 5.1 Sampling Select the specimens according to the directions in IS0 1957. 5.2 Number and dimensions Take at l
42、east three test specimens each measuring not less than 250 mm x 250 mm, noting the direction of manufacture. 5.3 Conditioning Condition the test specimens until they are in equilibrium with the standard atmosphere for testing textiles. 6 Procedure 6.1 Initial measurement of the specimen Make all mea
43、surements on the conditioned specimen when it is completely flat; this can be achieved by use of the glass plate (4.2) or other means. On the conditioned specimen, measure the distance between the edges parallel to the direction of manufacture and between the edges at right angles to the direction o
44、f manufacture, each at two locations approximately 200 mm apart. If required by the method of measuring adopted, mark the pair of reference points, for example by the use of steel pins 14.4), approximately 200 mm apart on the edge parallel to the direction of manufac- ture and also on the edge at ri
45、ght angles to the direction of manufacture. Make all measurements on the back of the specimen to the nearest 0,05 mm. NOTE - Products made of discrete layers. for example ioani-backed constructions, should be measured on both the backing and the use- surface, and the results of both measurements giv
46、en in the test report.

47、est specimen, lying freely on the perforated and lac- quered shelves, in the drying oven (4.3), controlled at 60 f OC. Keep the specimen in the drying oven for 2 h, then remove it and measure the distance between the two parallel edges or the two sets of marks to the nearest 0,05 mm, within between
48、6 and 7 min of removing the specimen from the oven. Immerse the test specimen, laid flat, in water at a temperature of 20 f 2 OC and allow it to soak in the water for 2 h. Remove the specimen from the water, taking precautions to avoid distorting its shape. Excess moisture may be removed by plac- in
49、g the specimen between sheets of blotting paper. Within 5 f 1 min of removing the specimen from the water, again measure the distance between the two parallel edges or the two sets of marks as specified in 6.1. Dry the test specimen for 24 h in the drying oven at 60 f 2 OC in the same conditions as before. Within between 6 and 7 min of removing the specimen from the oven again measure the distance between the two parallel edges or two sets of marks as s
