Closed Space Aerosol Tester

Standards:

ASTM D3065

Scope of Application:

The Closed Space Aerosol Tester is used to determine if a spray aerosol product creates a flammable atmosphere when dispersed in a confined volume. This is evaluated by discharging a specified quantity of the aerosol into a standard-sized drum or enclosed vessel and introducing an ignition source (typically a flame) at a defined time or during discharge. The tester records whether ignition occurs and potentially measures the time to ignition or the resulting pressure rise in the case of an explosion. This data is used to classify the aerosol's flammability hazard according to regulatory requirements. It is applicable to a wide variety of spray aerosol products across consumer, industrial, and commercial sectors.

Product Advantages:

The Closed Space Aerosol Tester offers several advantages for conducting this critical safety test:

Automated and Safe Operation: The fully automated test process minimizes manual intervention, enhancing safety, especially given the inherent flammability hazards. The protective enclosure and ventilation system further contribute to safety.

Reliable Ignition and Detection: Precise control over the aerosol spraying, ignition source introduction, and dual detection system (pressure and photosensitive sensors) ensures reliable identification of ignition or explosion events, even for fast deflagrations.

Simulates Realistic Hazard: Replicates the scenario where an aerosol is discharged into a closed or poorly ventilated space, providing relevant safety data.

Standard Compliant: Designed to meet the requirements of relevant international and national standards for aerosol flammability testing.

Data Logging and Reporting: Supports automatic data storage, parameter setting, and report viewing, streamlining documentation and analysis.

Environmental Monitoring: Real-time monitoring of temperature and humidity ensures that tests are conducted under controlled environmental conditions as specified by standards.

Product Features:

1. It adopts an embedded processor and the Windows CE operating system. 2. With an 8 - inch liquid - crystal touch screen, it can display the test status in real - time. 3. It integrates two working modes: the "standard mode" and the "custom mode". 4. The aerosol can sprays automatically, and the aerosol can clamping device can automatically turn the can upright and upside - down. 5. Automatic timing during spraying. 6. With a dual - detection module consisting of a pressure sensor and a nanosecond - level photosensitive sensor, it can automatically detect whether the flame is burning or whether an explosion occurs in an enclosed space. 7. It is equipped with a ventilation system to promptly discharge the smoke and unburned aerosol in the drum, ensuring the accuracy of the test and the safety of the experimenters. 8. The test process is fully automated, requiring no manual intervention. It supports functions such as parameter setting, data storage, and report viewing. 9. It is equipped with a temperature and humidity module to monitor the temperature and humidity of the test environment in real - time.
