Remark:DDZ’ means low smoke & halogen,flame retardant

2.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.

Low halogen: under stipulated testing conditions, HCI content ofsmoke emitted in firing is less which conforms tostipulated indices.

Flame retardant: under stipulated testing conditions, the testedsample is fired.After removing from source,flamespreads within stimulated range, remnant flame willgo out on itself within stipulated time.
