The following is a brief description of some common oxygen index test standards and guidelines:
1. ASTM D2863: Standard test method for measuring the oxygen index of plastic materials. This test method describes the evaluation of the combustion performance of plastics by determining the minimum concentration of oxygen to support their combustion. The test uses standardized oxygen index equipment and standardized specimen sizes.
2. ISO 4589-2: Standard test method for measuring the oxygen index of plastic materials at room temperature. The standard describes the evaluation of the burning properties of materials by measuring the minimum oxygen concentration required to sustain combustion on a standardized specimen. The test uses standardized oxygen index equipment and standardized specimen sizes.
3. UL 94: A standard issued by the United States Safety Laboratory (UL) for evaluating the burning performance and fire resistance of plastic materials. The standard is divided into several classifications that categorize materials into different ratings (e.g., V-0, V-1, V-2, etc.) based on their burning properties. The test methods include both horizontal and vertical placement.
4. GB/T 2406.2: Chinese national standard, corresponding to ISO 4589-2, for measuring the oxygen index of plastic materials. The standard describes the evaluation of a material's combustion performance by means of the minimum oxygen concentration required to sustain combustion on a standardized specimen. Tests are performed using standardized oxygen index equipment and standardized specimen sizes.
In addition to the above standards, there are industry-specific guidelines and specifications such as IEC 60695 for the electronics industry and ASTM E1354 for the construction industry. These guidelines provide industry-specific oxygen index test methods and requirements to evaluate the combustion performance of materials in their respective applications.
When performing oxygen index testing, the appropriate standards and guidelines should be followed to ensure accuracy and repeatability of the test. These standards and guidelines provide detailed guidance on specimen preparation, test environments, equipment calibration, data recording and reporting to ensure consistent and comparable test results.
Please note that the standards and guidelines mentioned above are only a sampling of common documents related to oxygen index testing. Depending on your specific needs and industry, there may be other applicable standards and guidelines available. It is recommended that applicable standards and guidelines be carefully researched and followed prior to actual testing.
