ASTM D 2863, ISO 4589-2 Automatic Limited Oxygen Index (LOI) Tester


   Introduction:   

Automatic Limited Oxygen Index (LOI) Tester is for the determination under the test conditions specified in oxygen and nitrogen gas mixture just to maintain a minimum sample combustion oxygen concentration required. This tester equipped with the imported oxygen concentration sensor, to make sure the measurement accuracy and durability. For the assessment of the performance of homogeneous combustion of solid materials, laminates, foams, films and films under specified conditions.


   Standards:   

ASTM D 2863

ISO 4589-2

NES 714
