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.
IP67 Test Methods
Verification Protocol
Standardized verification protocols define the procedures for assessing the protection of enclosures against temporary immersion in water. Protocols such as ip67 test methods require the equipment to remain submerged at a depth of one metre for a duration of thirty minutes. This protocol ensures that electronics can survive accidental flooding or brief underwater operation.
Immersion Protocol
Precise control of timing and depth is required for a valid result. During the execution of ip67 test methods, the device remains powered off unless the manufacturer specifies active operation. The temperature of the water must stay within five degrees of the device temperature to prevent pressure differentials from sucking water through seals.
This thermal equilibrium is maintained throughout the thirty minute duration to ensure the validity of the ingress data.
Depth Accuracy
Calibrated tanks provide the necessary head pressure for the evaluation. The tank used for ip67 test methods must have a calibrated depth gauge to ensure the lowest point of the enclosure reaches the required distance from the surface. A technician measures the water density and temperature before the timer starts.
Seal Evaluation
Post-test inspection involves opening the housing to check for internal moisture. No water may be present on live parts for a passing grade to be issued.
