2、主要名詞術語解釋
低煙:在規定試驗條件下,試樣受熱分解或燃燒釋放出的煙比較少，符合規定的指標特性。
低鹵:在規定試驗條件下,試樣燃燒時放出的鹵化氫氣體的含量比較少，符合規定指標的特性。
阻燃:在一定的試驗條件下，試樣被燃燒，在撤去火源后，火焰的蔓延僅在規定的范圍內，殘焰或殘灼在規定的時間內能自行熄滅的特性。
Explanation of Main Noun Term
Low smoke: under stipulated testing conditions, smoke out ofdecomposition with heat or emission in firing is less.which conforms to stipulated indices.
