IPXX Protection Rating Chart_Cover

How much kPa is measured by IP protection level and how to set the parameters of the air tightness tester?

This paper introduces the method of setting airtightness test parameters for IP66 to IP69 protection classes, including test pressure, instrument recommendation, test duration, etc. It also describes the method of defining test parameters and the four phases of establishing enterprise IP airtightness test standards, emphasizing that parameter settings need to be based on data-based decision-making and continuous optimization.
