ISO4589-2 ASTM D2863 LOI Limiting Oxygen Index Tester

Last month, the GD-ISO4589-3A Elevated-temperature Oxygen Index Tester was shipped to Sri Lanka.The Elevated-temperature Oxygen Index Tester is designed and produced according to ISO 4589-3 (Elevated-temperature test) and British naval engineering standards NES 715.

What is the oxygen index test?Oxygen concentration values are known as the Oxygen Index (OI) or, historically, the Limiting Oxygen Index (LOI). The oxygen concentration is measured using a paramagnetic oxygen analyzer and is controlled by varying the relative flow of oxygen and nitrogen through a ve

Common flame retardancy tests include burn test, limiting oxygen index, glow wire test, smoke test and so on. The purpose of the flame retardant test is to evaluate the combustion characteristics of the material, that is, to test the sample by simulating the actual combustion conditions, and to eval
