Waterproof/Dustproof/Shockproof Properties of
the Product
The product has a protection rating (JIS C 0920) for waterproof
property equivalent to IPX5
*1
and IPX7
*2
and dustproof property
equivalent to IP5X
*3
on the condition that the back cover is securely
closed (based on testing by the Company).
The product also achieves a shockproof property compliant with MIL
standards
*4
(based on testing by the Company).
*1 IPX5 means that the cell phone continues to function as a phone after
being subjected to a water jet (approximately 12.5 liters/min) discharged
from a water pouring nozzle (inner diameter: 6.3 mm), from all directions
and approximately 3 meters away from the cell phone for at least 3
minutes.
*2 IPX7 means that the cell phone continues to function as a phone after
being gently lowered into a tank filled with still tap water (at room
temperature) to the depth of 1 meter, immersed at the bottom for
approximately 30 minutes and then taken out of the tank.
*3 IP5X means that the cell phone continues to function and safely maintain
functioning as a phone after being placed in a test device containing 75
µm-particles and agitated for 8 hours and then removed. (Intrusion of
particles is not completely blocked.)
*4 MIL standards compliance
MIL-STD-810G Method 516.7 as per the US Department of Defense:
According to standards complying with Shock-Procedure IV, the product
is tested by being dropped from a height of 1.22 m in 26 directions onto
plywood (lauan).
* This does not guarantee resistance against all types of shock. As this
assumes shock resistance during usage in everyday situations, care
should be taken as breakage may occur if thrown, forcefully dropped,
or otherwise subjected to excessive shock. Droppage may cause
scratches even if functionality is not affected.
