2、rnment agency 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 intere

3、sts 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 expressed by such representatives. CGSB has been accred

4、ited by the 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 publ

5、ishes 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 sectors. Both CGSB standards and CGSB national standards are developed in conformance with the policies described in the CGSB Policy Manual

6、for the Development and Review of Standards. CGSB standards are subject to review and revision 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 st

7、andards 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, is found in the CGSB Catalogue, which is published annually and is available without charge u

8、pon request. More information is available about CGSB products and services at our Web site www.tpsgc-pwgsc.gc.ca/ongc-cgsb. 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 j

9、udge 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 associated with its use. Anyone using this stan

10、dard 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 injury or damage that may occur during

11、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 of this standard are expressly advised

12、 that determination of the validity of any such patent rights is entirely their own responsibility.

13、a (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 members, standardization is helping to

14、 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 national economy, supporting sustainabl

15、e 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 of the Canadian standards development

16、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; mechanism for dispute resolution; openness an

17、d 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 of Canada (NSC) is a standard prepared

18、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 capable individuals whose collective intere

19、sts 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 significant and timely contribution to t

20、he 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 approving standards as NSCs rests with:

30、 the combustion resistance of mattresses when in contact with a lighted cigarette.This method covers the resistance of mattresses to ignition only by a burning cigarette and does not relate to their resistance to any other source of ignition or fire condition.The testing and evaluation of a product

31、against this standard may require the use of materials and/or equipment that could be hazardous. This standard does not purport to address all the safety aspects associated with its use. Anyone using this standard has the responsibility to consult the appropriate authorities and to establish appropr

32、iate health and safety practices in conjunction with any applicable regulatory requirements prior to its use. CGSB neither assumes nor accepts any responsibility for any injury or damage that may occur during or as the result of tests, wherever performed.2 Principle The surface of a mattress assembl

33、y is exposed to a lighted cigarette as the standard ignition source in a draft-protected environment. Individual specimens are assessed by observing the maximum distance of charring or melting on the specimen surface in any horizontal direction from the nearest point of the original location of the

34、cigarette and by determining whether combustion continues in the mattress covering and within each mattress assembly after the cigarette is extinguished.3 Terms and definitionsFor the purposes of this method, the following terms and definitions apply:3.1 corethe main support system such as springs,

35、foam or fluid that may be present in a mattress.3.2 mattress a ticking filled with a resilient material used alone or in combination with other products, intended or promoted for sleeping upon (excluding sleeping bags).3.3 ticking the outermost layer of fabric or related material that encloses the u

36、pholstery and core.3.4 upholstery all material, either loose or attached, between the ticking or between the ticking and the core of the mattress.2CAN/CGSB-4.2 No. 27.7-2013CGSB 2013 All rights reserved4 Apparatus and materials4.1 Flammability tester (see Figures 1 and 2): the test device comprises

37、an uncovered flame-resistant box approximately 300 x 300 x 300 mm. Within the box, a platform (approximately 295 x 295 mm) is mounted on a scissor jack. The test specimen, which is mounted on this platform, can be clamped into position by raising the jack and compressing the edges against a clamping

38、 surround. The firmness of the specimen can be varied by adjusting the height of the platform. The box cover shown in Figures 1 and 2 is used to extinguish the fire in the box.4.2 Firmness tester (durometer): the purpose of this instrument is to measure the firmness of the mattress assembly under te

39、st. Measurement is achieved by local depression of the specimen with a spring loaded probe, reaction to the spring loading being displayed on a dial gauge. The durometer1should measure force up to 142 gf and have an accuracy of 2.8 gf, and should have a flat circular probe tip measuring 1 cm2.4.3 Ci
