Regarding progressive numerical standard ratings, the short answer is no. The Ingress Protection standards evolved in the International Electric Code (European based). Recently, American manufacturers from many different perspectives have been testing their products with the IP standards. Underwriters Laboratories will now also test to the standard. The table is progressive only up to a point. It is assumed that an IPX6 will also meet IPX1-5. However, it is not assumed that an IPX6 will meet the IPX7 standard or that an IPX7 will pass a IPX6 test. The IPX6 standard for us is jet directed water up to 1500 PSI, 0 degree dispersion nozzle at 5-10 foot distances rotating all over the item for a period of one hour. The IPX7 is a gentle dunk for an hour at a depth of 1 meter for half an hour. Way, way different standard. Regarding this and the recent Strobes thread, be advised that all electronica is subject to failure in the marine environment. (No, duh ; )) I have replaced my Princeton Tech strobe twice now and also have replaced batteries in it when the unit was switched on accidentally and left on til it died. If you carry electronica, test it as often as you paddle. I have headlamps and flashlights that get turned on accidentally in Pelican boxes and PFD pockets. My wife and I each have a VHF that were replaced due to failure in under one year. If you take a BCU or ACA assessment the likelyhood of an assessor asking you to turn on your strobe, headlight, flashlight or any electric stuff is quite high.
