CAN/CGSB-44.232-2008

1. SCOPE 1.1 This standard specifies test methods for measuring task chairs for office work environments and assessing their performance. 1.2 This standard also provides dimensional and adjustment requirements that respect generally accepted ergonomics guidelines such as those of CAN/CSA-ISO 9241-5-00, using NATICK/TR-89/044, 1988 as the source of anthropometric data. 1.3 The dimensional and adjustment requirements aim to address the estimated needs of the 5th to 95th percentile of adult office workers when in the seated position. 1.4 Quantities and dimensions used in this standard are given in metric units with imperial equivalents shown in brackets where appropriate. The metric units shall be regarded as official in the event of dispute. 1.5 This document contains requirements for chair dimensions and features that are based on the widely accepted ergonomics practices, along with the best practices and knowledge of the committee members. These dimensions and features are complex and if not specified correctly, some combinations thereof, while meeting the requirements of the standard, may result in task chairs that are inappropriate for some uses or users. It is important for the users of this standard to understand the task(s) to be performed by the chair’s user along with the individual’s dimensional needs when specifying dimensions and option features given in this standard. 1.6 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 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.
