Automotive Connector Sand and Dust Test Chamber
The Automotive Connector Sand and Dust Test Chamber is designed to evaluate the dust resistance and sealing performance of automotive connectors, housings, and related components. It simulates harsh dusty environments to verify the integrity and reliability of enclosures and electrical assemblies under controlled airflow and particulate conditions. The system ensures consistent, repeatable testing and helps manufacturers validate product compliance with international and domestic dust protection standards.
Application
This test chamber is suitable for a variety of automotive and electrical components that require dust resistance testing:
Automotive connectors and wire harnesses
Lighting components including headlights and tail lights
Instrument panels and electrical housings
Door lock assemblies and steering systems
Other sealed automotive parts that require verification of dust ingress protection (IP rating)
It is primarily used to simulate airborne dust exposure and assess sealing, enclosure integrity, and long-term durability of sensitive automotive components.
Standards
The chamber can be used to perform tests compliant with multiple standards:
(1) GB 2423 — Environmental testing for electrical and electronic products
(2) GB 4706 — Safety of household and similar electrical appliances
(3) GB 4208 — Ingress protection (IP) rating for electrical enclosures
(4) DIN 40050-9 — Protection of automotive electrical connectors
(5) IEC 60529 — IP rating testing for enclosures
(6) ISO 20653 — Road vehicles — Degrees of protection (IP code) for electrical equipment

Test Procedures
Install the test samples on the provided sample racks inside the chamber.
Fill the dust supply system with the selected particulate material.
Set the airflow velocity, vibration duration, and dusting program via the PLC interface.
Start the test; observe samples through the tempered glass door.
For cyclic tests, verify intervals and dust settling according to the program.
Upon completion, switch off the system, release any residual dust, and remove the samples.
Evaluate the sealing, ingress, and dust accumulation to determine compliance with standards.
Maintenance Information
Regularly clean and inspect the metal mesh and interior chamber surfaces.
Replace or refill dust supply materials as needed.
Periodically check fan operation and bearings for wear.
Inspect electrical contacts, relays, and PLC system for proper functionality.
Calibrate airflow and vibration settings annually to maintain testing accuracy.
Ensure the chamber is kept in a dry, well-ventilated area to prevent corrosion.
