Figure-3 IP67 Protection Level Application Scenarios

How to do IP67 waterproof grade test? Test standards, methods, precautions full analysis

2025-02-19

This article introduces the IP67 waterproof rating test guide. IP67 means that the product is completely dustproof and immersed under water for 30 minutes at 1 meter without water penetration. While traditional testing involves immersing the product in water, Precision Engineering's airtightness tester is much more efficient and accurate. Its equipment is suitable for a wide range of industries, and it also offers IP68, IP69 and non-standard customization services.

Popularization: product sealing leakage test rating standards and methods for details

2025-02-06

This paper describes the rating criteria and methods for product leakage tests for sealing. Leakage is the migration process of gas molecules driven by differential pressure, and the leakage rate is the measurement index. Test rating needs to consider the leakage medium, leakage rate, test pressure and time and other factors. Commonly used methods include immersion method, pressure decay method, differential pressure comparison method and tracer gas method.
