MIL-STD-1472E
5.6 Anthropometry.
5.6.1 General Design and sizing shall ensu~ accommodation,compatibility,operability,and
maintainabilityby the user population. Generally,
design limits shall be based upon a range from the
5th pementile female (see Table I) to the 95th percentile male values for critical body dimensions, as
appropriate, except for Naval aviator special populations (see 5.6.4). This design range from the 5th
to 95th percentile values will theoretically provide coverage for 90 percent of the user population for
that dimension; however, where two or more dimensions am used simultaneously as design
parameters, appropriate muk.ivariate data and techniques should be utilized,
5.6.2 AnthmPornetric data. See dimensions for the standing body, seatedbody, depth and
breadth, circumferences and surfaces, hands and feet, and head and face in MIL-HDBK-759. The
anthropometric data presented in MIL-HDBK-759 are intended to provide general design guidance,
MIL-HDBK-743 should be consulted for more extensive data,
5.6.3 Use of Data. Use of these data shall consider (a) the nature, frequency, safety, and
difficulty of the related tasks
to be performed by the opemtor or
wearer of the equipmen~ (b) the
position of the body during performance of these tasks; (c) mobility or flexibility requirements
imposed by these tasks; and (d) increments in the design<ritical dimensions imposed by the need to
compensate for obstacles and projections.
5.6.3.1 Adjustments. Because the above-cihxl anthropometric &ta represent nude body
measurements, suitable allowancxx in design-criticid dimensions shall be made for light or heavy
clothing, flying suits, helmets, boots, body armor, load-carrying equipment, protective equipment,
and otherworn or carried items, when utilizing these data for design criteria
5.6.3.2 Clearance dimensions. Clearance dimensions (e.g., for passageways and accesses),
which must accommodate or allow passage of the body or parts of the body, shall accommodate the
95th percentile values for applicable body dimensions.
5.6.3.3 Limitimz dimensions. Limiting dimensions (e.g., reaching distance, control movement,
displays, test points, handrails) which restrict or tue limited by extensions of the body shall
accommodate the 5th ~tile values for applicable body tinsions.
5.6.3.4 Adjustable dimensions. Seats, restraint systems, safety harnesses, belts, controls or
any equipment that must be adjusted for the comfofi or performance of the individual user shall be
adjustable over the range of the 5th to 95th percentile values for the applicable body member(s).
5.6.3.5 ChXl@ and txrsonal e@nment. Clothing and personal equipment (including
protective or specialized equipment worn or carried by the individual) shall be designed and sized to
aceomsrtodate at least b 5th through the 95th percentile values of body dimensions. pertinent
dimensions of essential or critical equipment (e.g., aviators’ helmets) shall be based on the Ist and 99th
percentile values.
5.6.4 Spec

Populations. Where equipment will be used, inclusively or exclusively, by
selected or specialized segments of the military population (e.g., Army tank crews, Navy divers, ek. )
or popu Iation ranges otherthan the 5- 95th percentiles (e.g., disproportionate anthrqometric
accommodation test cases), appropriate available anthropometric data on these specialized populations,
contained m MIL-HLX3K-743, shall bc utlhzed for dcslgn and slzmg cmcm. Where equpmcm IS
