Thanks iwire. I'm finding out that the ones listed for use in a patient care area are ones that come with a medical cart that itself is listed as an assembly. The power strips themselves are not listed for that application. Below is a clipping from a UL article.
Some UL Classified carts include
relocatable power taps as an integral
part of the cart. These are Recognized
Component Special Purpose Relocatable
Power Taps (SPRPTs), which are specifically
investigated to supply power to the plugconnected
equipment on the cart and to
verify compliance with the Standard for
Health Care Facilities, NFPA 99, Section
8.4.1.2.4.2. This standard is applicable when
two or more power receptacles supplied by
a flexible cord are used to supply
power to plug-connected components
of a movable equipment assembly that
is rack-, table- or pedestal-mounted.
SPRPTs have not been investigated for
stand-alone use in patient care vicinities.
