1、Canadian General Standards Board I CAN/CGSB-155.21-2000 Recommended Practices for the Provision and Use of Workwear for Protection nst Hydrocarbon Flash Fire “ “ ? Standqrd OE Canada The CANADIAN GENERAL STANDARDS BOARD (CGSB), under whose auspices this National Standard of Canada has been developed

2、 is a government 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 relev

3、ant 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 expressed by such representatives. CGSB has b

4、een accredited 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 standar

5、ds 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 sectors. Both CGSB standards and CGSB national standards are developed in conformance with the policies described in the CGSB Poli

6、cy Manual for the Development and Maintenance 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

7、. Changes 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, is found in the CGSB Catalogue, which is published annually and is available

8、without charge upon request. An electronic version, ECAT, is also available. More information is available about CGSB products and services at our Web site - http:/www.pwgsc.gc.ca/cgsb. Although the intended primary application of this standard is stated in its Scope, it is important to note that it

9、 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 materiais andor equipment that could be hazardous. This document does not purport to address ail the sa

10、fety 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 regulatory requirements prior to its use. CGSB neither assumes nor accepts any re

11、sponsibility 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 standard may be the subject of patent rights. CGSB shall not be held responsible for identifying any or all such

12、 patent rights. Users of this standard are expressly advised that determination of the validity of any such patent rights are entirely their own responsibility.

13、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 towards the further development and improvement of voluntary standardization in the national intere

14、st. 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. assisting and protecting the consumer, facilitating domestic and intemational trade, and furthering i

15、nternational 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 among the views of a number of capable individuals whose collective interests provide, to the grea

16、test 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 capable of making a significant and timely contribution to the national interest. Approval of a stan

17、dard 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 of the standard; this remains the continuing responsibility of the accredited standards-development

18、 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 cautioned to obtain the latest edition from the organization preparing the standard. The responsibilit

19、y for approving National Standards of Canada rests with the: Standards Council of Canada 270 Albert Street Suite 200 Ottawa, Ontario KIP 6N7 How to order -3 Publications: by telephone - (819) 956-0425 or - 1-800-665-CGSB (Canada only) by fax - (819) 956-5644 by mail - CGSB Sales Centre Ottawa, Canad

Technical definitions for many of the terms included here can be found in CANKGSB-4.175 (Parts 1, 3, 4, 6), CANKGSB-4.157, the Textile Labelling Act, a

34、s well as in specific test methodr referenced in this standard. The following definitions are applicable to this standard: Char (Produit de carbonisation) Carbonaceous residue resulting from pyrolysis or incomplete combustion. Charring is the same phenomenon that occurs when a material subjected to

35、fire becomes embrittled as it dries out, shrinks in size, and may break apart when any force or pressure is applied. Decontamination (Dcontamination) Removal of the contaminant from the protective clothing by laundering or dry cleaning, to the extent necessary to continue to meet the minimum perform

36、ance requirements specified in CAN/CGSB-155.20. Drip (Egoutter) To run or fall in drops or blobs. Ease (Aisance) The size requirements and tolerance of a garment which allows good fit and does not inhibit the natural body movement or the performance of any task. Fabric (Tissu) Yams used to manufactu

37、re fabrics are made of a single fibre type or multiple fibre blends. Fabrics can either be woven or knitted. Each type of fabric has specific mechanical and physical properties that can have a distinct impact on wear, durability and comfort. Fabric Blend (Mlange de tissu) A fabric in which two or mo

38、re textile fibres are combined to produce fabrics with special performance qualities. Fibre (Fibre) The correct term is manufactured fibre: a class name for various genera of filament, tow, or staple produced from fibre forming substances which may be (1) polymers synthesized from chemical compounds

39、, (2) modified or transformed natural polymers, or (3) glass. Fibre is the first step of textile development that will result in the making of yarn, which is then made into fabric. Fibre can be a natural fibre (vegetable or animal), e.g. cotton, wool, flax. or it can be a man-made or synthetic fibre

40、, e.g., aramid, rayon. While certain fibres have inherent flame resistance, other fibres do not. However, many fibres that do not have inherent flame resistance can be treated with a flame retardant to give them flame resistance after the fibre has been processed into a yam and the yarn is made into

41、 a fabric. 2 CANKGSB-155.21-2000 STDDCGSB 155*2L-OO-CAN/CGSB-ENGL 2000 W L874b50 0034924 218 = Fire (noun) (Feu) A process of combustion characterized by the emission of heat accompanied by smoke andior flame. Flame (noun) (Flamme) A zone of combustion in the gaseous phase with emission of light. Fi

42、ame (verb) (Flamber) To undergo combustion in the gaseous phase with emission of light. Fiame Resistance (Rsistance la flamme) The property of a material whereby flaming combustion is slowed, terminated or prevented. Flame resistance can be imparted by specific treatment or can be an inherent proper

43、ty of the basic material. For this document. flame resistance implies that flaming combustion is slowed and the material self-extinguishes and does not continue to bum when removed from the flame. Fhe-retardant reament (Ignifugation) A chemical process or treatment whereby flame retardant is imparte

44、d to a fabric which if it was not treated, would bum andor melt when exposed to a flame. Inherently Flame-resistant Fibre (Fibre ininflammable) Manufactured fibres whose generic material makes them naturally flame resistant without a chemical treatment. Such fibres have slower flaming combustion and

45、 self-extinguish when exposed to a flame of short duration during testing. Generic Term (Terme gnrique) A name given to a class of fibres with similar chemical makeup. Examples of generic terms and fibres are aramid, cellulose fibres, polybenzimidazole (PBI), protein fibres. (See Appendix A - Supple

46、mental Glossary.) Knitted Fabric (Tricot) A structure produced by interlooping one or more ends of yarn or comparable material. Examples are jersey, interlock and rib. Melt (Fondre) The physical process of changing from solid to liquid by action of heat, as evidenced by flowing or dripping. Protecti

47、ve Workwear (Vtements de travail de protection) Single to multi-layer protective workwear such as, but not limited to, coveralls, trousers, shirts, jackets, rainwear and parkas, designed to provide protection against hydrocarbon flash fire. Protective workwear covers the body from the neck to the wr

48、ists and feet and may or may not cover the neck, head, hands and feet. Static Electricity (Electricit6 statique) An accumulation of negative or positive charge on the surface of the garment due to inadequate dissipation of electricity. The accumulated static electricity may discharge to materials wi

49、th a different potential, producing sparks that may have sufficient energy to ignite a flammable mixture of hydrocarbon. Woven Fabric (Tiss) Woven fabrics consist of interlaced yarns that are perpendicular to each other. Those yarns running lengthwise (parallel to the length of the fabric) are called warp direction yams. Those yams running widthwise (across the width of the fabric) are called filling or weft direction yarns. Woven fabrics have a number of textures and appearances based on variations of this perpendicular placement of yarns. Examples are plain weave, twill,
