What is the ISO standard for limiting oxygen index?

 

1. ISO 4589-2: This standard specifies methods for testing the LOI of solid materials. It covers the preparation of samples, test devices and test procedures and provides formulas for calculating LOI.

 

2. ISO 4589-3: This standard provides guidance for the testing of LOIs for thin sheet materials including films, sheets, coatings, etc. It covers the selection of different test methods. It covers the selection of different test methods, sample preparation and test conditions.

 

3. ISO 4589-4: This standard applies to LOI testing of textiles. It describes methods for LOI testing using textile samples in customized test sets.

 

Please note that the above are just a few examples of ISO standards related to LOI. There are actually other standards that cover different types of materials and specific test methods. If you need detailed information about the ISO standards for a specific material or test method, please check the official ISO website or purchase the corresponding standard documents for accurate and exhaustive information.
