CSA Preface
This is the first edition of CSA Standard CAN/CSA-ISO 9241-3, Ergonomic requirements for office work with visual display terminals (VDTs) - Part 3: Visual display requirements, which is an adoption without modification of the identically titled ISO (International Organization for Standardization) Standard 9241-3:1992 (first edition, 1992-07-1 5). This ISO Standard was developed by the ISO Technical Committee ISO/TC 159 SC 4. It is part of the series of ISO 9241 Standards that address ergonomic requirements for office work with visual display terminals.
In conjunction with the adoption of this Standard, CSA is issuing a new edition of CSA Standard Z412, Guideline on Office Ergonomics. Basic principles and information from the ISO Standards have been used in the development of this CSA guideline.
This Standard was reviewed for Canadian adoption by the CSA Technical Committee on Office Ergonomics under the jurisdiction of the Strategic Steering Committee on Occupational Health and Safety, and has been formally approved by the Technical Committee. A list of the members of the Technical Committee is available upon request. This Standard has been approved as a National Standard of Canada by the Standards Council of Canada.
Scope
This part of ISO 9241 establishes image quality requirements for the design and evaluation of single and multi-colour VDTs. The requirements are stated as performance specifications, and the evaluations provide test methods and conformance measurements. It should be noted that, at present, the recommendations are based on Latin, Cyrillic, and Greek origin alphabetic characters, and Arabic numerals.
Other factors that affect performance and comfort are coding, format, and the style of presentation of information. With the exception of their visual aspects, they are not covered by this part of ISO 9241.
This part of ISO 9241 applies to the ergonomic design of electronic displays for office tasks. Office tasks include such activities as data entry, text processing, and interactive inquiry, but do not include recommendations for other specific applications such as computer-aided design or process control.
It is planned to issue recommendations on such applications separately.
