ENVIRONMENTAL DUST SIMULATION
Arizona Test Dust Test
Dust Testing and Arizona Testing, commonly referred to as the Arizona Dust Test, is a standardized environmental simulation used to evaluate the resistance of components, devices, and enclosures to dust intrusion. It is primarily used to assess the ingress protection (IP) rating, especially for IP5X (dust protected) and IP6X (dust tight), and to ensure product performance under dusty or desert-like conditions.
Purpose of Dust Testing
- To determine the protection of enclosures against harmful dust ingress.
- To evaluate mechanical performance, sealing, and functionality of products exposed to dusty environments.
- Simulate real-world conditions like deserts, off-road terrains, or industrial sites.

TEST DUST USED
Common Test Dust Classifications
The most common test dusts are:Arizona Test Dust (AC Fine Dust or AC Course Dust)ISO 12103-1 Dust Types:
— A1: Ultrafine Test Dust— A2: Fine Test Dust (formerly Arizona Test Dust)— A3: Medium Test Dust— A4: Coarse Test Dust
PROCEDURE
Test Duration & Post-Test Evaluation
Test Duration:— IEC 60529 (IP5X/IP6X): 8 hours (or as specified)— MIL-STD-810: Up to 6 hours per cycle, multiple cycles may be applied.Post-Test Evaluation:
— Inspect for dust ingress.— Functional checks.— Check seals and electrical/mechanical components.Typical properties of Arizona Fine Dust (ISO 12103-1 A2):
| Parameter | Specification |
|---|---|
| Particle size | 0–120 µm |
| Median particle size (D50) | ~20 µm |
| Composition | Silica, feldspar, calcite, gypsum, etc. |
| Counter Type | Digital counter with automatic stop |
| Moisture content | 0.2% |
EVALUATION
Acceptance Criteria
— IP6X: No penetration of dust into critical areas for IP6X.— IP5X: Limited or no impact on function for IP5X.— MIL-STD: In MIL-STD: no degradation in performance, and operational capabilities must be maintained.
