Explanation of Nouns and Terms:

Low smoke: Under the specified test conditions, the smoke released from the thermal decomposition of the sample during combustion is relatively small, which meets the specified indicator characteristics.
Halogen free: Under the specified test conditions, the content of hydrogen gas released during the combustion of the sample is extremely low or even non-existent, meeting the specified index characteristics.
Flame retardant: Under certain test conditions, the sample is burned, and after removing the fire source, the spread of the flame is only within the specified range, and the residual flame or burn can be extinguished on its own within the specified time.
