ah, maybe not it seems. Conflicting info exists out there - doesn't it always? It is an odd system if it is only partially cumulative, but, the last link says it is not cumulative, so I included it as well.
"IPx7 means that a device can handle actual immersion into water. Anything less means that the device can handle various degrees of water sprays or jets, but that, up to IPx5, limited ingress is acceptable. An IPx7 device, on the other hand, can fall into a puddle or shallow stream and survive. There are some limits, though, and manufacturers usually state the degree of IPx7 protection, like "30 minutes at a depth up to 3 feet."
