While it is true that the Animas R-1000 and the Paradigm have IPX8 rating,
but that fact can easily mislead people into thinking that they have been
tested to the same degree of watertightness.
Basically the standards group that set up the IPX system specifies testing
at a specific depth for a specific period (3 feet for 30 minutes, I believe)
in order for a pump to receive the IPX7 rating. Any pump that is tested for
watertightness in excess of the standard for the IPX7 rating is given the
IPX8 rating -- regardless of the degree to which they exceed the IPX7
In the case of the Paradigm, it received the IPX8 rating for watertightness
testing at a depth of *8* feet for 30 minutes. In contrast, the Animas
R-1000 (while receiving the same IPX8 rating) was tested at a significatly
higher standard: a depth of 12 feet for 24hours.
In my personal opinion as a parent of a pumper, anything that is rated for
watertightness for only 30 minutes isn't very useful for my child. You may
feel comfortable if the pump is splashed or briefly submerged, but 30
minutes of watertightness isn't of much use for an afternoon at the pool, let
alone a day at the beach . . . Which is why a major reason why we chose the
Animas pump for my daughter.
