This product is protection-rated (JIS C 0920) at
IPX5/8-
*1
water resistance and seawater capability
*2
as well as IP6X-equivalent
*3
dust resistance when the
back cover and USB cover are completely attached (by
Company test methods).
The product also meets 27 ruggedization test
requirements, based on 22 categories of the US
Department of Defense's MIL-STD-810G standards

non-breakage or non-fault.
*1 IPX5 equivalent means that the product will maintain its
operability as a phone even if it is sprayed with water from a 6.3
mm diameter nozzle at a distance of about 3 meters for more
than 3 minutes at a rate of about 12.5 liters per minute from
any direction. IPX8 equivalent indicates no water seepage and
phone capability is maintained even when gently submersed
and left at the bottom of a tank for about 30 minutes filled
with still, normal-temperature tap water at a depth of 1.5 m.
*2 Indicates no water seepage and phone capability is maintained
even when submersed in normal-temperature, 20-kPa
(maximum depth of 2.0 m) seawater
*
for about 60 minutes.
* Seawater: Evaluation made with Company original standards
using artificial seawater simulate the seawater composition
of the Japanese coast. Regarding use at pools, product has
been assessed according to Japanese domestic disinfection
standards.
*3 IP6X-equivalent indicates ability to resist dust intrusion even
