Standards: BS EN ISO9831 and GB/T 45104

    Sample Requirements

1 Particle size ≤ 1.0 mm

2 Sample should be Packed with Lens Paper

Test Procedure

Add a specified amount of distilled water (BS EN ISO9831:5ml , GB/T 45104:10ml) to oxygen bomb ,Weigh approximately 0.9-1.1 g of sample into lens paper of known mass and calorific value, wrap it, and place it in a metal crucible. Install the ignition wire or ignition cotton thread, and close the oxygen bomb lid. Place the oxygen bomb into the calorimeter. Input the sample weight and lens paper weight, and the instrument will automatically complete the calorific value determination and result calculation.
