ANSI/ASTM D2863 Digital Oxygen Index Apparatus For Lab

The ANSI/ASTM D2863 Digital Oxygen Index Apparatus is a laboratory instrument used for conducting the oxygen index test according to the ASTM D2863 standard. This apparatus is designed to measure the minimum concentration of oxygen required to support combustion of a material in a controlled environment.

The digital oxygen index apparatus typically consists of a combustion chamber, a gas mixing system, and sensors to monitor the oxygen concentration. The test specimen is placed inside the chamber, and a precise mixture of oxygen and nitrogen is introduced. The oxygen concentration is gradually reduced, and the combustion behavior of the material is observed. The oxygen concentration at which the material just stops burning is recorded as the oxygen index.

The digital oxygen index apparatus provides accurate and repeatable results, allowing for the evaluation of the flammability characteristics of various materials. It is commonly used in research laboratories, quality control, and material testing facilities to assess the fire performance of materials and aid in product development and safety standards compliance.
