During simulated movement exposures, the gloves were in continual movement greater than 80% of the time. A default exposure time of 30 min, equivalent to 60 cycles, was used to evaluate the effect of simulated movement on chemical permeation. Only one glove (Glove 3) required greater than 30 min to provide the necessary permeation data.
