What is ISO 3098-3:2021 ?

ISO 3098-3:2021, also known as "Plastics - Determination of Burning Behavior by Oxygen Index - Part 3: High-Temperature Test, " is a crucial international standard that sets guidelines for measuring the relative flammability of plastics in high-temperature environments. This standard is developed by the European Committee for Standardization (CEN) and the International Organization for Standardization (ISO) and is designed to provide manufacturers with a common framework for evaluating the flammability of their products.

The purpose of ISO 3098-3:2021 is to ensure the safety of materials used in various industries, such as construction, automotive, and electronics. By evaluating the burning behavior of materials, this standard helps manufacturers identify potentially hazardous substances and develop safer products.

ISO 3098-3:2021 is based on the oxygen index method, which involves determining the minimum concentration of oxygen required to support combustion. Materials with higher oxygen indexes are considered less flammable, while those with lower indexes are more prone to burning.

The standard covers various aspects, including fire retardancy, ignition resistance, and the propagation of flame. By providing manufacturers with guidelines for measuring the flammability of their products, ISO 3098-3:2021 plays a crucial role in ensuring the safety of materials used in various industries.
