Test Procedures

Pre-Test Preparation

Clean chamber walls with neutral detergent (pH≥7.5) and rinse with deionized or distilled water

Ventilate chamber at least six air changes to reduce background pollutants: formaldehyde ≤6 µg/m³, TVOC ≤50 µg/m³, single pollutants ≤5 µg/m³

Verify calibration of temperature/humidity sensors, solar simulation system (e.g., 1.200 W/m² ±20 W/m²), and roller dynamometer if installed

Sample and Parameter Setup

Position vehicle centrally within chamber, ensuring level orientation and uniform airflow over vehicle surfaces

Connect vehicle power supply and sensors (temperature, fuel consumption, emission monitoring)

Test Process Control

Activate automated control system to monitor and maintain temperature, humidity, solar intensity, and airflow (e.g., roller fan speed up to 260 km/h)

For thermal cycling tests, program temperature rise, hold, and drop phases while recording vehicle performance metrics (cold start, AC cooling rate, etc.)

Safety and Emergency Measures

Continuously monitor chamber pressure and emission concentrations

System triggers alarms and shuts down power if temperature deviates by >±2°C or emissions exceed limits

Entering the chamber requires stopping the test and ventilating for at least 30 minutes

Maintenance Information

Regular cleaning of chamber walls, doors, and observation windows to prevent contamination

Periodic calibration of temperature, humidity, and solar simulation systems

Inspection of power outlets, lighting, and emergency systems

Verification of airlock operation and pressure balance valves

Scheduled maintenance of roller dynamometer interface and support structures
