Canadian Standards Association

The Canadian Standards Association (CSA), under whose auspices this National Standard has been produced, was chartered in 1919 and accredited by the Standards Council of Canada to the National Standards system in 1973. It is a not-for-profit, nonstatutory, voluntary membership association engaged in standards development and certification activities.

CSA standards reflect a national consensus of producers and users — including manufacturers, consumers, retailers, unions and professional organizations, and governmental agencies. The standards are used widely by industry and commerce and often adopted by municipal, provincial, and federal governments in their regulations, particularly in the fields of health, safety, building and construction, and the environment.

Individuals, companies, and associations across Canada indicate their support for CSA’s standards development by volunteering their time and skills to CSA Committee work and supporting the Association’s objectives through sustaining memberships. The more than 7000 committee volunteers and the 2000 sustaining memberships together form CSA’s total membership from which its Directors are chosen. Sustaining memberships represent a major source of income for CSA’s standards development activities.

The Association offers certification and testing services in support of and as an extension to its standards development activities. To ensure the integrity of its certification process, the Association regularly and continually audits and inspects products that bear the CSA Mark.

In addition to its head office and laboratory complex in Toronto, CSA has regional branch offices in major centres across Canada and inspection and testing agencies in eight countries. Since 1919, the Association has developed the necessary expertise to meet its corporate mission: CSA is an independent service organization whose mission is to provide an open and effective forum for activities facilitating the exchange of goods and services through the use of standards, certification and related services to meet national and international needs.

L’Association canadienne de normalisation (CSA), sous les auspices de laquelle cette Norme nationale a été préparée, a reçu ses lettres patentes en 1919 et son accréditation au sein du Système de Normes nationales par le Conseil canadien des normes en 1973. Association d’affiliation libre, sans but lucratif ni pouvoir de réglementation, elle se consacre à l’élaboration de normes et à la certification.

Les normes CSA reflètent le consensus de producteurs et d’usagers de partout au pays, au nombre desquels se trouvent des fabricants, des consommateurs, des détaillants et des représentants de syndicats, de corps professionnels et d’agences gouvernementales.

L’utilisation des normes CSA est très répandue dans l’industrie et le commerce, et leur adoption à divers ordres de législation, tant municipal et provincial que fédéral, est chose courante, particulièrement dans les domaines de la santé, de la sécurité, du bâtiment, de la construction et de l’environnement.

Les Canadiens d’un bout à l’autre du pays témoignent de leur appui au travail de normalisation mené par la CSA en participant bénévolement aux travaux des comités de la CSA et en appuyant ses objectifs par leurs cotisations de membres de soutien. Les quelque 7000 volontaires faisant partie des comités et les 2000 membres de soutien constituent l’ensemble des membres de la CSA parmi lesquels ses administrateurs sont choisis. Les cotisations des membres de soutien représentent une source importante de revenu pour les services de soutien à la normalisation volontaire.

L’Association offre des services de certification et de mise à l’essai qui appuient et complètent ses activités dans le domaine de l’élaboration de normes. De manière à assurer l’intégrité de son processus de certification, l’Association procède de façon régulière et continue à l’examen et à l’inspection des produits portant la marque CSA.

Outre son siège social et ses laboratoires à Toronto, la CSA possède des bureaux régionaux dans des centres vitaux partout au Canada, de même que des agences d’inspection et d’essai dans huit pays. Depuis 1919, l’Association a parfait les connaissances techniques qui lui permettent de remplir sa mission d’entreprise, à savoir la CSA est un organisme de services indépendant dont la mission est d’offrir une tribune libre et efficace pour la réalisation d’activités facilitant l’échange de biens et de services par l’intermédiaire de services de normalisation, de certification et autres, pour répondre aux besoins de nos clients, tant à l’échelle nationale qu’internationale.

American National Standards Insititute

The American National Standards Institute (ANSI), Inc. is the nationally recognized coordinator of voluntary standards development in the United States through which voluntary organizations, representing virtually every technical discipline and every facet of trade and commerce, organized labor and consumer interests, establish and improve the some 10,000 national consensus standards currently approved as American National Standards.

ANSI provides that the interests of the public may have appropriate participation and representation in standardization activity, and cooperates with departments and agencies of U.S. Federal, state and local governments in achieving compatibility between government codes and standards and the voluntary standards of industry and commerce.

ANSI represents the interests of the United States in international nontreaty organizations such as the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC). The Institute maintains close ties with regional organizations such as the Pacific Area Standards Congress (PASC) and the Pan American Standards Commission (COPANT). As such, ANSI coordinates the activities involved in the U.S. participation in these groups.

ANSI approval of standards is intended to verify that the principles of openness and due process have been followed in the approval procedure and that a consensus of those directly and materially affected by the standards has been achieved. ANSI coordination is intended to assist the voluntary system to ensure that national standards needs are identified and met with a set of standards that are without conflict or unnecessary duplication in their requirements.

Responsibility of approving American National Standards rests with the

Preface

This publication represents a basic standard for safe operation, substantial and durable construction, and acceptable performance of portable type gas camp stoves. It is the result of years of experience in the manufacture, testing, installation, maintenance, inspection and research on portable type gas camp stoves. There are risks of injury to persons inherent in appliances that, if completely eliminated, would defeat the utility of the appliance. The provisions in this standard are intended to help reduce such risks while retaining the normal operation of the appliance.

Nothing in this standard is to be considered in any way as indicating a measure of quality beyond compliance with the provisions it contains. It is designed to allow compliance of portable type gas camp stoves, the safety construction and performance of which may exceed the various provisions specified herein. In its preparation, recognition has been given to possibilities of improvement through ingenuity of design. As progress takes place, revisions may become necessary. When they are believed desirable, recommendations or suggestions should be forwarded to the CSA America, 8501 East Pleasant Valley Road, Cleveland, Ohio 44131, or the Canadian Standards Association, 5060 Spectrum Way, Suite 100, Mississauga, Ontario, Canada L4W 5N6.

Safe and satisfactory operation of portable type gas camp stoves depends to a great extent upon its proper installation, use and maintenance. It should be installed, as applicable, in accordance with the National Fuel Gas Code, ANSI Z223.1/NFPA 54; the Natural Gas and Propane Installation Code, CSA B149.1.

Users of this American National Standard/CSA Standard are advised that the devices, products and activities within its scope may be subject to regulation at the Federal, Territorial, Provincial, state or local levels. Users are strongly urged to investigate this possibility through appropriate channels. In the event of a conflict with this standard, the Federal, Territorial, Provincial, state or local regulation should be followed.

THIS STANDARD IS INTENDED TO BE USED BY THE MANUFACTURING SECTOR AND BY THOSE APPLYING THE EQUIPMENT AND BY THOSE RESPONSIBLE FOR ITS PROPER INSTALLATION. IT IS THE RESPONSIBILITY OF THESE USERS TO DETERMINE THAT IN EACH CASE THIS STANDARD IS SUITABLE FOR AND APPLICABLE TO THE SPECIFIC USE THEY INTEND.

CAUTION NOTICE: This American National Standard may be revised or withdrawn at any time. The procedures of the American National Standards Institute, Inc., require that action be taken to reaffirm, revise or withdraw this standard no later than five (5) years from the date of approval. Purchasers of American National Standards may receive current information on all standards by calling or writing the American National Standards Institute, Inc., 25 West 43rd Street, Fourth Floor, New York, N.Y. 10036, (212) 642-4900.

EFFECTIVE DATE: An organization using this standard for product evaluation as a part of its certification program will normally establish the date by which all products certified by that organization should comply with this standard.

History Of The Development Of Standard For Portable Type Gas Camp Stoves

(This History is informative and is not part of the standard.)

With the onset of the Free Trade Agreement between the United States and Canada on January 2, 1988, significant attention was given to the harmonization of the United States and Canadian safety standards addressing gasfired equipment for residential, commercial and industrial applications. It was believed that the elimination of the differences between the standards would remove potential trade barriers and provide an atmosphere in which North American manufacturers could market more freely in the United States and Canada. The harmonization of these standards was also seen as a step toward harmonization with international standards.

The draft harmonized standard was based on current coverage from the American National Standard for Portable Camp Cook Stoves for Use with Propane Gas, Z21.72-1982, and the Canadian Standard for PortableType Gas Camp Stoves, CAN1-11.2-M79. On September 19, 1997 the Z21/(Interim CSA) Joint Gas Refrigerators and Portable Camping Equipment Subcommittee reviewed by letter ballot the first draft harmonized portable type gas camp stoves standard. At its February 45, 1998 meeting, in light of comments received, the joint subcommittee agreed to adopt the revised draft standard for public review and comment. The revised draft portable type gas camp stoves standard was distributed for an industrial review during June 1998.

At its November 1998 meeting, the subcommittee assigned a task group to review the comments received and to revise the draft standard. At its June 1999 meeting, the joint subcommittee reviewed the revised draft standard prepared by the camping equipment task group and agreed to distribute substantive changes to the camp stoves draft standard for another industry review. The substantive revisions to the draft standard were distributed for an industrial review during September 1999.

During its January 25-26, 2000 meeting, the joint gas refrigerators and portable camping equipment subcommittee recommended the proposed draft standard to the Accredited Standards Committee Z21/83 and the (Interim CSA) Standards Steering Committee for approval.

The proposed draft was approved by the Z21/83 Committee on April 13, 2000, and by the CSA Technical Committee by letter ballot dated March 10, 2000.

The first edition of the harmonized American National Standards/CSA Standard for Portable Type Gas Camp Stoves was approved by the Canadian Interprovincial Gas Advisory Council (IGAC) on June 1, 2000, and by the American National Standards Institute, Inc. (ANSI), on September 14, 2000.

This the second edition of the portable type gas camp stoves standard was appoved by the IGAC on August 23, 2011, and by ANSI on March 17, 2011.

Previous editions of this standard and addenda there to appoved by the IGAC and ANSI are as follows: ANSI Z21.72-2000 • CSA 11.2-2000

ANSI Z21.72a-2001 • CSA 11.2a-2001

ANSI Z21.72b-2002 • CSA 11.2b-2002

The following identifies the designation and year of the harmonized standard: ANSI Z21.72-2011 • CSA 11.2 2011

Note: This edition of Z21.72 • CSA 11.2 incorporates changes to the first edition of Z21.72-2000 • CSA 11.2-2000 and addenda thereto. Changes are denoted by a vertical line in the margin.
