Standard Ingress Protection Test Methods for Sensor Housings
Verify IP ratings using accredited ISO/IEC 17025 test dossiers with Category 1 vacuum suction and thermal pre-conditioning differential immersion steps.
Non-Destructive Leak Testing
Sealed Integrity
Verification procedures assess the hermeticity of an enclosure without causing any physical or chemical damage to the test specimen. Employing non-destructive leak testing allows manufacturers to inspect one hundred percent of their production run rather than relying on statistical sampling. This approach ensures that every shipped device meets the required ingress protection standards before deployment.
Common Modality
Pressure decay and tracer gas detection are the most widely used techniques for evaluating seal performance in a production environment. For non-destructive leak testing, pressure decay involves monitoring the pressure drop inside a pressurized component over a set period, while tracer gas methods use helium to detect microscopic leaks. Both methods leave the tested component fully functional and ready for assembly or shipment.
Operational Advantage
Output maximization is achieved because tested units do not have to be discarded or refurbished after the inspection process. In contrast to destructive testing methods like the bubble emission test, which can damage internal electronics or leave residues, non-destructive leak testing maintains the clean, dry state of the component. This allows the testing stage to be integrated directly into the assembly line, minimizing material waste and reducing the overall cost of quality control while maintaining high-throughput rates.
Performance Limit
Equipment sensitivity limits the size of the leak that can be detected in a rapid cycle time. While non-destructive leak testing is highly effective for high-throughput lines, detecting extremely small leaks may require longer cycle times that reduce production speeds.
