This part of ISO 7250 provides a description of anthropometric measurements which can be used as a basis for comparison of population groups and for the creation of anthropometric databases (ISO 15535). The basic list of measurements specified in this part of ISO 7250 is intended to serve as a guide for ergonomists who are required to define population groups and apply their knowledge to the geometric design of the places where people work and live. In addition the list serves as a basis for extracting one and two dimensional measurements from three-dimensional scans (ISO 20685). This list may serve as a guide for how to take anthropometric measurements, but it also gives information to the ergonomist and designer on the anatomical and anthropometrical bases and principles of measurement which are applied in the solution of design tasks. This part of ISO 7250 is intended to be used in conjunction with national or international regulations or agreements to assure harmony in defining population groups and to allow comparison of anthropometric data among member bodies. In its various applications, it is anticipated that the basic list will be supplemented by specific additional measurements. Annex A shows the correspondence of dimensions described here with their use in ISO 14738 and ISO 15534.
