This International Standard provides principles derived from the application of anthropometric data to the design of workstations. It is based on ergonomics and currently available anthropometric measurements. This International Standard specifies the body's space requirements for normal operation of equipment in sitting, sit-standing and standing positions. It includes space demands for maintenance, repairing and cleaning work. This International Standard does not give recommendations specifically for visual display terminal workstations at machinery. For this purpose, ISO 9241-5 can be used in conjunction with this International Standard. Safety distances intended to prevent hazard zones being reached by upper and lower limbs are provided in ISO 13857.
