1、CAN/CGSB-44.227-2008Supersedes CAN/CGSB-44.227-2000Free-standing Office Desk Products and ComponentsICS 97.140National Standard of CanadaThe CANADIAN GENERAL STANDARDS BOARD (CGSB), under whose auspices this National Standard of Canada has been developed is a government agency within Public Works an
2、d 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 interests including producers, consumers a
3、nd 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 accredited by the Standards Council of Can
4、ada 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 publishes as national standards, CGSB pr
5、oduces 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 for the Development and Review of St
6、andards. 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 standards are issued either as separat
7、e 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 upon request. An electronic version,
8、CAT, is also available. More information is available about CGSB products and services at our Web site www.ongc-cgsb.gc.ca. 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 ju
9、dge 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 stand
10、ard 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 o
11、r 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 are entirely their own responsibility.

13、COUNCIL OF CANADA is the coordinating body of the National Standards System, a coalition of independent, autonomous organizations working towards the further development and improvement of voluntary standardization in the national interest. The principal objects of the SCC are to foster and promote
14、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 international trade, and furthering international cooperation in the field of standards. A National Standa
15、rd of Canada (NSC) is a standard prepared or reviewed by an accredited Standards Development Organization (SDO) and approved by the SCC according to the requirements of CAN-P-2. Approval does not refer to the technical content of the standard; this remains the continuing responsibility of the SDO. A
16、 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 (including consumers), and others with relevant interests, as may be appropriate to the
17、subject in hand. It normally is a standard, which is capable of making a significant and timely contribution to the national 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
18、 edition from the SDO, which publishes the standard.

SCOPE1.1 This standard provides dimensional and performance requirements for safety, durability and structural adequacy of free-standing components of office desk prod
27、ucts.1.2 This standard also provides dimensional and adjustment requirements that respect generally accepted ergonomics guidelines or standards, such as those of CAN/CSA-ISO 9241-5-00, using NATICK/TR-89/044, 1988 as its source of anthropometric data.1.2.1 The dimensional and adjustment requirements
28、 aim to address the estimated needs of the 5th to 95th percentile of adult office workers when in the seated position.1.3 The selected methods for measuring desk products and components and for assessing their performance are based on the actual field and product-testing experience of the members of
