Anthropometric Design Principles and Dimensions

The principles and data in this chapter apply to the sizing of equipment, accesses, and clearances to provide physical compatibility of the human body (in terms of physical dimensions) and design of interfaces such as: hardware, chairs, hatches, doorways, consoles, panels, and clothing. Sizing of these interfaces is usually done within the context of performing general tasks, such as reaching a control, viewing over a console, sitting in a chair, or exiting through a hatch. Throughout this Part 1 we have been presented with extensive guidance that relates to anthropometric dimensions, and specifically, in respect to Chap. 5 , Integration of controls, displays, and alarms; Chap. 6 , Computer workstation design; Chap. 7 , Manual valve operation, access, location, and orientation; Chap. 9 , Stairs, ladders, ramps, walkways, platforms and hatches; and Chap. 10 , Maintenance considerations. Building on what we have already discussed in these previous chapters, much of the anthropometric guidance presented in the main body of this chapter is applicable to the size and strength characteristics of North American males. Since this book is intended to have international appeal, this chapter is provided so that the main body anthropometric guidance can be modified for use in designs to be operated and maintained by peoples of other regions with different body dimensions. The science of anthropometry focuses on the measurement of human variability of body dimensions and strength as a function of gender, race, and regional origin. The application of anthropometry to design establishes limits (or boundary conditions) for sizing equipment for human use. In essence, it defines size limits in design based on the dimensions of the anticipated population of operating and maintenance personnel.
