IP6X is the highest dust protection rating in the IEC 60529 standard. It specifies that a case is dust-tight — no dust can penetrate the interior even after 8 hours of continuous exposure to circulating talcum powder in a dust chamber. Our Series 8 cases were tested by CTI to verify IP6X compliance.
Test Conditions
- Dust type: Talcum powder (median particle size 75μm, per IEC 60529)
- Dust quantity: 2 kg per cubic meter of chamber volume
- Chamber temperature: 23°C ± 2°C
- Humidity: <25% RH
- Test duration: 8 hours continuous
- Sample size: 3 units
Test Results
After 8 hours of exposure, all 3 sample cases showed zero dust ingress when opened and inspected under 10x magnification. The test was conducted per IEC 60529 Section 13.4 (Category 1 enclosure).
Engineering Features Enabling IP6X
- Continuous gasket seal: TPU gasket runs the full perimeter of the lid, with no gaps or splices
- Latching force: Each latch applies 80-120 N of clamping force, distributed over the gasket area for uniform compression
- Gasket groove: 0.5mm interference fit between gasket and groove, preventing dust bypassing
- Cable pass-through (optional): IP-rated cable glands for cases with electronic components
Customer Impact
IP6X performance is critical for operations in:
- Desert environments (Middle East, North Africa, Australia)
- Mining and quarrying (Australia, Chile, South Africa)
- Cement and construction (global)
- Agricultural settings with high particulate
