5.2 Hand grip(s) shall allow for a full “power grip” similar to grabbing a rung
on a ladder or holding a pistol.
Acceptance criterion: allows for a full power grip in either pronated (palm
facing down) or neutral (handshake position) posture.
NOTE A: Acceptable handle types include cylindrical, circular,
triangular, or enclosed.
NOTE B: See §6 for handle design recommendations.
Power Grips
5.3 Single hand lift force
Acceptance criterion: maximum 37.8 N (8.5 lbf). This value includes a
15% capacity reduction due to cleanroom glove use.
5.4 Two hand lift force
Acceptance criterion: maximum 64.5 N (14.5 lbf). This value includes a
15% capacity reduction due to cleanroom glove use.

6.0 (Handle dimensions are correct for use of bare hand or use of typical
cleanroom gloves).
NOTE A: A recommended practice for selecting a handle design is to
first determine the force requirements before choosing a
handle design that is best suited for the intended forces,
motions and environment. Handle design recommendations
for various hand forces and handgrips are located in ¶¶6.2–
6.6.
NOTE B: Handles should anticipate the use of gloved hands.
