Products & services
DUST EXPLOSION TESTING
Xefra dust explosion testing capabilities are provided in a dedicated industry-based laboratory. The laboratory team has extensive practical experience dealing with problems associated with dust handling and reactive chemical processing. Dust and gas explosion services complement laboratory testing capabilities. Our ATEX Testing facilities include: --Combustible Dust Screening Test: the Go and No-Go Test is the first step in screening for the possibility of dust explosibility. --Minimum Ignition Energy (MIE) Test: determines the energy required to ignite dust, critical in evaluating risk from low-energy sources like static electricity. --Burning test: assesses the flammability and combustibility characteristics of dust samples. --Minimum Auto-ignition Temperature Tests (MIT and LIT): evaluate the temperatures at which dust clouds in air on hot surfaces autoignite, vital for setting safe operating temperatures in dusty environments. --Dust and Gas Lower Explosivity Limit (LEL): establishes the concentration levels at which dust and gas mixtures become explosive. --Maximum Explosion Over-pressure (Pmax) and Dust Specific Characteristic (Kst): these tests determine the severity of potential dust explosions, aiding in designing effective explosion protection measures. --Gas Specific Characteristic (Kg), Limiting Oxygen Concentration (LOC), and Volumetric Resistance of Dust: these additional assessments contribute to a comprehensive understanding of dust explosivity and safety. --Combustibility Index (BZ) Test: evaluating the combustible properties of dust samples.
