Hi all,
We declared that our pump is IPX4 device. The test lab believes that the device fails the waterproofing requirement because IEC 60320-1 inlet (IPX0) is used. The water can enter the inlet and short the pins. The IP rating is still invalid even though the device can luckily pass the IP-test, if there are no additional design features. So, construction will be inspected before doing the IP-test.
My questions are:
1) Should the IP rating be determined by the result of IP-test or by both the constructive measures and IP-test?
2) Should the connector of cord be connected or detached from inlet during the IP-test?
Any input will be appreciated.
