IP and NEMA Ratings
IP 6 7
Definition:
The first numeral defines the amount of
protection against penetration of solid objects into the
housing.
The second numeral defines the amount
of protection against liquids penetrating the housing.
Additional information on ratings can be found
in the following chart or the 1976 IEC Publication,
Classification of Degrees of Protection Provided
by Enclosures.
Example: What is IP67?
le:What is IP67?
Complete protection of live parts. Protection
against the penetration of dust. Additionally,
it will be protected while immersed in water.
Testing Criteria:
:
1. Test Class:
IP67 test
Conditions:
1m head of water over the test piece for a duration of
30 minutes.
Room temperature ±5 °C
Test:
Insulation and operation
2. Test Class:
IP68 test (Encapsulated products)
Conditions:
1m head of water over the test piece for 24 hours of
operation under water, with cyclical activation and
deactivation under nominal loading Cycle time 2 hours
Room temperature ±5 °C
Test:
Insulation and operation
3. Test Class:
IP69K test
Conditions:
