Tested down to the details
IP protection code, second digit
DIN EN 60529
Digit
Protection against water
0 No protection
1 Protection against vertically falling drops of water
2 Protection against falling water drops, when the enclosure
tilted up to 15°
3 Protection against water spray that falls at an angle up to 60° from vertical
4 Protection against splashed water from all sides
5 Protection against jets of water from all angles
6 Protection against strong jets of water
6K Protection against strong high-pressure jets of water
7 Protection against sporadic submersion
8 Protection against continuous submersion
In the IPX6 dynamic test, the enclosure is subjected to a
strong jet of water (100 l/min ow rate). The jet is directed
all around the enclosure for three minutes.
The IPX7/IPX8 static test is a completely different type of
test. Here the enclosure is submerged under 1 metre of
water for 30 minutes (for IPX7) or for 72 hours (for IPX8).
The test is passed successfully if the water is not able
to damage the enclosure. An internal Weidmüller test
specication also stipulates that no ingress of water is
acceptable.
For the American market, a proof of impermeability can be
carried out according to UL 50E (a hose-down test). In such
a test, the enclosure is subjected to a water stream from all
sides with a ow of 240 l/min.
Degree of protection against mechanical impacts
(IK code)
An enclosure may be subjected to external impacts and
certain impact forces during actual use. These impacts must
not impair or damage the functionality of the enclosure.
The enclosures must undergo an IK impact resistance
test to establish this. In this test, a test hammer falls on
the test piece from a height of 700 mm with an impact
force of 7joules in accordance with IEC 60079-0 (for
Exapplications), or a force of 10joules (IK09) in accordance
with DIN EN 50102 (for industrial applications).
