How to Test Garnet Abrasive Conductivity | ASTM D4940-25 Standard Demo

Demonstration of an ASTM D4940-25 conductivity test for 30/60 mesh garnet abrasive. Conductivity testing helps assess the level of water-soluble ionic contamination in abrasive media, which is an important quality consideration for surface preparation applications. 📊 Test Parameters & Procedure: • Sample: 30/60 Mesh Garnet Abrasive • Test Method: ASTM D4940-25 • Ratio: 300 mL Garnet + 300 mL Reagent Water (1:1 volume ratio) • Mixing: Stir for 1 min, rest for 8 min, then stir for 1 min • Filtration: Filter through filter paper and discard the first 10 mL of filtrate • Measurement: Measure the conductivity of the extract and account for the conductivity of the source water For technical data sheets, COA, or sample requests, feel free to contact us or visit our website. #GarnetAbrasive #ASTMD4940 #ConductivityTest #SurfacePreparation #WaterjetCutting #IndustrialMinerals
