The specification is IPX7.  I have checked what is IPX7 from wikipedia.org. The URL of about IP code is http://en.wikipedia.org/wiki/IP_Code.   

My understanding is this
IPX7
First digit "X" means  that it don't have any  protection against  hazardous parts (e.g., electrical conductors, moving parts) and the ingress of solid foreign objects (sand, duct ..)

Second digit is "7" means "immersion up to 1 m" is okay".  Detail explanation is "Ingress of water in harmful quantity shall not be possible when the enclosure is immersed in water under defined conditions of pressure and time (up to 1 m of submersion)."

However this is just the factory specifications...
