A sampling of hospital grade tests
Plugs &
Connectors Receptacles Testing
Crushing Test
For plugs and connectors, a gradually escalated and removed
crushing force between two steel plates of 500 lbf is applied to
the bodies of the wired devices. Devices must not break, deform
or otherwise become incapable of function
Ground Contact Overstress Test
After conditioning of connectors, the ground contact must retain
a weighted test pin while face down for a length of time and
have no breakage that would affect the integrity of live parts
enclosures
Ground Contact Temperature Test
Conditioned connectors are wired in a series and mated with
powered hospital grade plugs for 1 hour, during which the
temperature of the ground contact cannot rise more than
54º above ambient temperature
Impact Resistance Test
Plugs and connectors are wired then subjected to a dropped
cylindrical weight, after which they cannot exhibit any breakage
or other body damage, must still function properly
Mechanical Drop Test
Corded and wired plugs and connectors must maintain their
physical integrity and pass a dielectric voltage-withstand test of
2x the device rating plus 1000V after being dropped via their cord
to strike against a block for an average of 1,000 hits
Plug Connection and Separation Test
Connectors used for the grounding contact overstress test are
conditioned repetitively by severe wiggling, counter-rotational
twisting, and severe breaking action of a test plug before having
to retain a weighted test pin while face down for a length of time
Strain Relief Test
Corded and wired plugs and connectors in fixed positions must
sustain 30 lbf gradually applied cord pulls, 10 lbf rotary cord
motion for 2 hours and abrupt removal tests, all without any
conductor, conductor insulation, or cord jacket cuts, breakage or
displacement
Abrupt Plug Removal Test
For receptacles, this test includes a series of steps involving
conditioning, abrupt angular plug pulls via a 10 lb weight dropped
from 2 feet and then demonstration of subsequent plug retention
under weight, all without breakage or other internal damage
Assembly Security Test
Receptacles must withstand 100 lbf of force applied from within
the contacts via a “push-out” tool without mechanical breakage,
deformation, or loss of grounding continuity and then be able to
retain a weighted test pin while face down for a length of time
Impact Test
Receptacles are mounted in a cast metal box with a metal wall-
plate and then subjected to a dropped 5 lb cylindrical weight from
a height of 18 inches, after which they must exhibit no breakage
and still function properly
