Product Details
CSA Preface
This is the first edition of CSA Standard CAN/CSA-ISO 9241-7, Ergonomic requirements for office work with visual display terminals (VDTs) - Part 7: Requirements for display with reflections, which is an adoption without modification of the identically titled ISO (International Organization for Standardization) Standard 9241-7:1998 (first edition, 1998-04-01). 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. Thiis 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 VDTs used in luminous environments that may cause reflections from the screen. The requirements are stated as performance or design specifications, and test methods are provided.
- applies to the ergonomic design of direct-view electronic displays for office tasks, including such activities as data entry, text processing and interactive inquiry. Office tasks are performed indoors, without exposure to direct sunlight. The recommendations can possibly be appropriate for other tasks, including process control, graphic design and computer-aided design, but their applicability has not been established.
- applies to monochrome and multicolour displays. The following displays and similar types are excluded from the scope of this part of ISO 9241: multi-user projection displays, transparent displays and virtual image displays.
- applies to VDTs for which its test method is suitable. The test method is limited to VDTs whose colour and/or luminance contrast does not vary strongly as a function of the viewing direction, and whose reflection properties do not vary as a function of the logical state of the screen. The test method is suitable for emissive VDT technologies, such as cathode ray tubes, and some flat panels.
NOTE - VDTs using display devices for which the test method of this part of ISO 9241 is not suitable (for example, liquid crystal displays) are directed to ISO 13406-2.
