This International Standard establishes principles for deriving dimensions from anthropometric measurements andapplying them to the design of workstations at non-mobile machinery. It is based on current ergonomic knowledgeand anthropometric measurements.This International Standard specifies the body's space requirements for equipment during normal operation in sittingand standing positions.
