Oxygen Index Tester ISO 4589-2: Ensuring Fire Resistance Compliance The Oxygen Index Tester ISO 4589-2 is an essential fire testing equipment used to determine the minimum oxygen concentration needed for a material to sustain combustion. This test is crucial for assessing the flammability characteristics of materials, especially those used in industries where fire safety is critical, such as construction, automotive, and aviation. The ISO 4589-2 standard provides a reliable and standardized method for determining the oxygen index (OI) of materials, which helps ensure compliance with fire resistance and safety regulations. At KDM Global, we manufacture high-quality Oxygen Index Testers that comply with the ISO 4589-2 standard, offering industries a reliable tool to evaluate material flammability and safety. Standards: The Oxygen Index Tester is designed to meet the following key standard: ISO 4589-2: This standard defines the method for determining the oxygen index of a material. The oxygen index (OI) is the minimum concentration of oxygen in a mixture of oxygen and nitrogen required for a material to sustain combustion. The higher the oxygen index, the more fire-resistant the material is. ISO 4589-2 is widely used to assess the flammability of materials used in applications such as building materials, textiles, and electrical components. How It Works: The Oxygen Index Tester â?? ISO 4589-2 works by exposing a sample of the material to a controlled mixture of oxygen and nitrogen gases. The apparatus then measures the oxygen concentration at which the material continues to burn or self-extinguish. The test results are reported as the oxygen index (OI), which reflects the fire-resistance properties of the material. Sample Preparation: A standardized sample is placed vertically in the test chamber. Mixture of Gases: The sample is exposed to varying concentrations of oxygen and nitrogen. Flame Behavior Analysis: The material is ignited and observed to determine if it will sustain combustion at specific oxygen concentrations. Oxygen Index Calculation: The minimum oxygen concentration required for combustion is calculated and reported as the oxygen index. Key Features: Compliance with ISO 4589-2: Fully compliant with ISO 4589-2, ensuring accurate and standardized testing for oxygen index determination. Precise Measurements: Accurately measures the oxygen index, providing valuable insights into material flammability and fire resistance.
