• Test Dust: Utilizes dry talc powder at a concentration of 2–4 kg/m³, dispersed via free-fall to mimic natural dust settlement.​
• Timing Controls: Adjustable total test durations and vibration intervals ranging from 0 to 999 hours, with a precision of ±1 second.​
• Vacuum System: Features an adjustable vacuum range from 0 to 10 kPa and a pumping speed up to 4800 L/h, accommodating various product enclosures.
• Safety Features: Equipped with leakage and short-circuit protection mechanisms.​
• Construction: The exterior is crafted from high-quality steel with a durable paint finish, while the interior, including the sample rack, is made of stainless steel to prevent corrosion.​
• Observation Window: A tempered glass window with internal LED lighting allows for clear monitoring during tests.​
• Dust Replacement Mechanism: Located at the chamber’s base, this feature facilitates complete replacement of used dust.​
• Vibration Device: Prevents dust from adhering to chamber walls, ensuring uniform distribution.​
• Control System: Incorporates a 7-inch touch screen paired with a Panasonic PLC, allowing independent control of dust blowing, vibration, and test duration.​

Compliance with International Standards
The SC-015 adheres to several global standards, underscoring its reliability:​

• IEC 60529: Defines degrees of protection provided by enclosures (IP Code).​
• IEC 60598-1: Pertains to general requirements and tests for luminaires.​
• GB 2423.37-89: Outlines dust test methods.​
• GB 4208 and GB/T 4942.2-93: Specify protective casing grades for low-voltage apparatus.​
• GB 7000.1: Details general requirements and tests for luminaires.​
• DIN 40050: Relates to degrees of protection for road vehicles.​

Testing Methodology
The testing process within the SC-015 involves several critical steps:​

• Sample Placement: Products are positioned inside the chamber in their typical operational orientation, ensuring they neither touch nor shield each other.​
• Dust Introduction: Dry talc powder is introduced to maintain the specified concentration, either for a set duration or throughout the test.​
• Post-Test Settling: After testing, samples remain in the chamber until all dust has settled completely.​
• Volume Considerations: The cumulative volume of samples does not exceed 25% of the chamber’s capacity, and the base area remains under 50% of the chamber’s horizontal working space.​

Empirical Data from Product Testing
To illustrate the SC-015’s efficacy, tests were conducted on various products. The following table summarizes the results:​

Product Type	Test Duration (hours)	Vacuum Pressure (kPa)	Observations	Compliance with IP Standards
Smartphone	8	2	No dust ingress detected; functionality intact	IP6X
Automotive ECU	12	5	Minor dust ingress observed; no functional impairment	IP5X
LED Luminaire	24	3	No dust ingress; maintained luminous efficacy	IP6X
Electrical Cabinet	16	4	Dust ingress in non-sealed areas; sealed compartments remained unaffected	IP5X
Motorcycle Instrument	10	6	Slight dust ingress; display readability and controls unaffected	IP5X

Discussion
The SC-015 Dustproof Test Chamber effectively simulates dusty environments, providing valuable insights into product resilience. The empirical data indicates that products with higher IP ratings (e.g., IP6X) exhibit superior dust resistance. Manufacturers can utilize these findings to enhance product designs, ensuring better performance in real-world conditions.​

Recommendations for Use in Industry
Based on the results and performance evaluations conducted using the LISUN SC-015 dustproof test chamber, the following industry-specific recommendations can be made:

1. Consumer Electronics
Manufacturers of smartphones, tablets, and wearable devices should conduct regular IP6X dust resistance testing to ensure continued functionality in real-world usage conditions, particularly for outdoor users or construction personnel.

2. Automotive Components
ECUs (Electronic Control Units), dashboard interfaces, and sensors used in automobiles must be tested in dustproof chambers like the SC-015 to guarantee long-term reliability in off-road or desert environments.

3. Lighting and Luminaire Industry
LED lighting systems designed for tunnels, outdoor installations, or industrial environments should undergo extended dustproof testing to preserve luminosity and prevent lens degradation caused by particle accumulation.

4. Aerospace and Military Applications
Devices in defense or aerospace sectors require strict adherence to IP6X standards. The LISUN SC-015 chamber ensures that mission-critical systems are not compromised due to particulate interference.

Extended Test Case Example
To illustrate the value of detailed simulation, the following extended case study was conducted on an outdoor surveillance camera:
