Hi,
I have an IP 67K rated switch, that has to withstand high-pressure and steam cleaning.
Since this component is fitted into enclosure chassis, I have to do air pressure testing in case there is leakage, damaging electronic components if do a water pressure test.
For IP 67K, the component will undergone water spraying with 80 °C water at 80–100 bar (~1160-1450) and a flow rate of 14–16 L/min.
If I do an air pressure test, what could be equivalent pressure I need to do at.
I am thinking to do at 1.8 PSI only, at least not to damage electronic components inside.
I understand water has more viscosity and more surface tension, compared to air.
Or should I ask if there is failure from air pressure test at 1.8 PSI, the IP 67K rated switch actually does not meet the IP rate?
Regards,
