Applications
1. Chemical Industry: Determine the Material Effects (MI) of chemical dusts such as organic synthesis intermediates and plastic powders to guide explosion-proof safety design in production/storage processes;
2. Food Processing Industry: Test the MI of food dusts such as flour and sucrose powder to optimize safety measures for dust control in workshops;
3. Mining/Materials Industry: Assess the ignition risk of dusts such as coal dust, aluminum dust, and wood dust to assist in the configuration of explosion-proof facilities in mines and material processing plants;
4. Light Industry: Test the MI of tobacco powder and plant fiber powder to support workshop safety management and risk classification;
5. Safety Testing Institutions: Conduct compliance testing and certification for dust explosion risks based on standards such as ASTM and IEC.
