Ngā painga o te hua
1. He iti te rahi o te matūriki o te hua, he pumau te pāmahana, he pai te mahi tukatuka, ā, he mārama pai hoki ngā hua tukatuka.
2. He iti noa te rahinga o te hua. Mā te tāpiri 2~3% ka eke ki te taumata UL94V-2 (1.6mm) ā, ka tineia tonutia i muri i te tango atu i te ahi.
3. Mā te tāpiri iti rawa o te 1% ka eke ki te taumata UL94V-2 (3.2mm).
4. He iti te ihirangi pūremu o ngā hua ārai-mumura, ā, ko te ihirangi pūremu o ngā hua ārai-mumura he ≤800ppm, e tutuki ana i ngā whakaritenga kore-halogen.
5. Ina mura ngā hua ārai-mumura, he iti te nui o te paowa, kāore he Sb2O3 i roto, ā, ka taea te whakamahi me te kore e tāpirihia he antioxidants.
Te tono hua
