Section 5
Chemical Resistance
Note: OMRON Test Method
Usage conditions: 10 m or less under water in natural conditions
1.No water ingress after 1 hour under water at 2 atmospheres of pressure.
2.Communications performance must be met after 100 repetitions of 30 minutes in 5
°
C water and 30
minutes in 85
°
C water.
Oil resistance (OMRON in-house standard)
Note: This OMRON in-house standard confirms resistance to cutting and other oils. It is equivalent to the
former JEM standard.

Protection against sprin-
kled water
Protects against sprinkled
water approaching at a maxi-
mum angle of 60× from verti-
cal towards the product.
Water is sprinkled for 10 min at a maximum angle of
60× to the left and right from vertical from the test
machine.
4
Protection against water
spray
Protects against water spray
approaching at any angle
towards the product.
Water is sprayed at any angle towards the product for
10 min from the test machine.
5
Protection against water jet
spray
Protects against water jet
spray approaching at any
angle towards the product.
Water is jet sprayed at any angle towards the product
for 1 min per square meter for at least 3 min in total
from the test machine.
6
Protection against high
pressure water jet spray
Protects against high-pres-
sure water jet spray approach-
ing at any angle towards the
product.
Water is jet sprayed at any angle towards the product
for 1 min per square meter for at least 3 min in total
from the test machine.
7
Protection underwater
Resists the penetration of
water when the product is
placed underwater at speci-
fied pressure for a specified
time.
The product is placed 1 m deep in water (if the product
is 850 mm max. in height) for 30 min.
