2、ermitted without license from IHS-,-,-The CANADIAN GENERAL STANDARDS BOARD (CGSB), under whose auspices this National Standard of Canada has been developed is a government agency within Public Works and Government Services Canada. CGSB is engaged in the production of voluntary standards in a wide ra

3、nge of subject areas through the media of standards committees and the consensus process. The standards committees are composed of representatives of relevant interests including producers, consumers and other users, retailers, governments, educational institutions, technical, professional and trade

4、 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 the Standards Council of Canada as a national standards-development organization. The standards that it develops and offers as

5、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 produces standards to meet particular needs, in response to requests from a variety of sources in bot

6、h 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 for the Development and Review of Standards. CGSB standards are subject to review and revision to ensure that they keep abreast of tech

7、nological 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 standards, includ

8、ing details on latest issues and amendments, and ordering instructions, is found in the CGSB Catalogue, which is published annually and is available without charge upon request. More information is available about CGSB products and services at our Web site www.tpsgc-pwgsc.gc.ca/ongc-cgsb. Although t

9、he 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. The testing and evaluation of a product against this standard may require the use of

10、 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 standard has the responsibility to consult the appropriate authorities and to establish appropriate health and safety practices in conjunct

11、ion 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. Attention is drawn to the possibility that some of the elements of this Canadian standar

12、d 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 that determination of the validity of any such patent rights is entirely their own responsibility. Further information on CGSB and its

13、 services and standards may be obtained from: The Manager Standards Division Canadian General Standards Board Gatineau, Canada 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

14、 development, promotion and implementation of standards. Through the collaborative efforts of Canadian standardization network 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 ove

15、rseen by SCC. The principal objectives of SCC are to foster and promote voluntary standardization as a means of advancing the national economy, supporting sustainable development, benefiting the health, safety and welfare of workers and the public, assisting and protecting the consumer, facilitating

16、 domestic and international trade, and furthering international cooperation in relation to standardization. An important facet of the Canadian standards development system is the use of the following principles: consensus; equal access and effective participation by concerned interests; respect for

17、diverse interests and identification of those who should be afforded access to provide the needed balance of interests; mechanism for dispute resolution; openness and transparency; open access by interested parties to the procedures guiding the standards development process; clarity with respect to

18、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 or reviewed by an SCC-accredited SDO and approved by the SCC according to NSC approval requirements. Approval does not refer to the tec

19、hnical 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 interests provide, to the greatest practicable extent, a balance of representation of general interests, producers, regulators, users (includ

20、ing 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 the Canadian interest. Those who have a need to apply standards are encouraged to use NSCs. These standards are subject to periodic revi

21、ew. 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: Standards Council of Canada 270 Albert Street, Suite 200 Ottawa, Ontario K1P 6N7, CANADA How to order Publications: by telephone 819-9

33、arette.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 against this standard may require the use of materials and/or equipment tha

34、t 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 appropriate health and safety practices in conjunction with any applicable regulat

35、ory 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 assembly is exposed to a lighted cigarette as the standard ignition source in a dr

36、aft-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 cigarette and by determining whether combustion continues in the mattress c

37、overing 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, foam or fluid that may be present in a mattress.3.2 mattress a ticking fill

38、ed 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 upholstery and core.3.4 upholstery all material, either loose or attached, b

39、etween the ticking or between the ticking and the core of the mattress.Copyright Canadian General Standards Board Provided by IHS under license with CGSBNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-2CAN/CGSB-4.2 No. 27.7-2013CGSB 2013 All rights reserved4 Appara

40、tus and materials4.1 Flammability tester (see Figures 1 and 2): the test device comprises 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

41、 be clamped into position by raising the jack and compressing the edges against a clamping 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): t

42、he purpose of this instrument is to measure the firmness of the mattress assembly under test. 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 ha

43、ve an accuracy of 2.8 gf, and should have a flat circular probe tip measuring 1 cm2.4.3 Cigarette2: the cigarette shall be without filter tip and made from natural tobacco, 85 2 mm long with a tobacco packing density of 270 20 kg/m3, and a mass of 1.1 0.1 g at 65 2% relative humidity (RH) and a temp

44、erature of 20 2C. The cigarette, when conditioned at 21 3C and 35 to 50% RH and ignited at one end, shall burn its entire length in 1500 150 s when placed horizontally on the surface of a glass fibre fabric3(205 5 g/m2).4.4 Polyurethane foam4: 300 5 x 300 5 x 25 5 mm with a density of 16 to 42 kg/m3

45、and a firmness of 21 to 61 on the prescribed durometer1. 4.5 Rule: graduated in millimetres to measure specimen thickness.4.6 Template: as shown in Figure 3.4.7 Fire extinguisher: should be immediately available at all times at the test location.5 Test specimens5.1 Test specimens shall be 300 5 x 30

46、0 5 mm. In the case of a quilted ticking or a deep panel scroll ticking, the specimens shall be cut so the stitch line is as close as possible to the centre of the mattress assembly. Unless otherwise specified, ten specimens shall be tested.5.2 Test specimens shall exclude any spring or fluid assemb

47、ly and shall includea) the entire mattress assembly, where its thickness does not exceed 50 mm, or, notwithstanding 5.2 c) and 5.2 d), where it can be reasonably accommodated in the flammability tester;b) all of the ticking and upholstery, where the thickness of such ticking and upholstery does not

48、exceed 50 mm, measured in an unrestrained condition;c) the outermost 50 mm of ticking and upholstery measured in an unrestrained condition, where the thickness of such ticking and upholstery is greater than 50 mm; or1A durometer that conforms to these requirements is the Model 302SL available from I
