Spray Aerosol Ignition Distance Tester
Spray Aerosol Ignition Distance Tester is a specialized device for measuring the ignition distance of spray aerosols, designed to assess fire hazards associated with aerosol products. It is suitable for spray aerosol products with a spray distance of 15 cm or greater.
Standards
United Nations Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria 31.4 Ignition Distance Test for Spray Aerosols
GB/T 21630-2008 “Dangerous Goods - Ignition Distance Test Method for Spray Aerosols”
GAT 536 “Classification and Test Methods for Fire Hazard of Flammable and Explosive Dangerous Goods”
NY/T 1860 “Guidelines for Determining Physicochemical Properties of Pesticides” Part 27: Flammability of Aerosols
Features
1) Embedded processor with Windows CE operating system.
2) 8-inch LCD touchscreen for real-time display of test status.
3) Integrated “Standard Mode” and “Custom Mode” operation.
4) Automatic spray dispensing with can holder that automatically positions cans upright or inverted.
5) Nanosecond-level photosensitive sensor detection module automatically monitors spray combustion.
6) Hybrid stepper motor drive with optical encoder ensures precise positioning of measurement points.
7) Ignition gun source produces a blue, non-luminous flame 4-5 cm high, with adjustable flame height.
8) Fully automated testing process requires no manual intervention, supporting parameter settings, data storage, and report viewing.
9) Dedicated fire-resistant bellows cover effectively prevents equipment contamination.
10) Equipped with a temperature and humidity module for real-time monitoring of test environment conditions.
11) Combustion gas source housed in a dedicated sealed chamber to ensure gas supply safety.
12) Streamlined testing process operates fully automatically after initiation, eliminating the need for personnel supervision and ensuring operator safety.
