Learn how to prepare coal and brick samples for oxygen bomb calorimeter testing, including drying, crushing, grinding, weighing, combustion aid selection, and common testing precautions.

A step-by-step guide for testing thermal conductivity of 90×90×190mm porous hollow clay bricks, complying with GB/T 10294 & ASTM C518, avoiding 3 key errors to ensure ≤3% accuracy.

In material R&D, industrial production, and quality inspection, thermal conductivity is a core indicator of material thermal performance, and a thermal conductivity tester is key to accurately measuring it. Indispensable for screening electronic component heat dissipation materials and evaluating building insulation performance, the tester often faces user issues like data deviation from non-standard operation and unmet needs due to improper selection.
