ISO 4589-2 Oxygen Index Test Apparatus Used In Flame Retardancy Testing Of Plastics

ISO 4589-2 Oxygen Index Tester

Product Introduce

ISO 4589-2 oxygen index test is an internationally accepted standard method for evaluating the combustion performance of materials in a mixed environment of oxygen and nitrogen. It is widely used in flame retardancy testing of products such as plastics, rubber, films, foams, fibers, composite materials and electrical materials. By determining the minimum oxygen concentration required to maintain combustion (oxygen index, OI), this test provides key data for material research and development, quality control and regulatory certification, and is suitable for flame retardant material evaluation in the fields of construction, electronics, automobiles, aviation, etc. The test must be carried out in a standard environment and equipment to ensure the accuracy and comparability of the results.

Standard

ISO 4589-2

a standard test method for determining the oxygen index (Oxygen Index, OI) of materials developed by the International Organization for Standardization (ISO), specifically "Plastics - Determination of combustion behavior - Part 2: Oxygen index method". This standard is used to evaluate the ability of materials to resist combustion under specific conditions and is widely used in the combustion performance testing of materials such as plastics, rubber, and fibers.
