Volume 3m³ IEC 61034-1 ~2 Smoke Density of Cables Burning Under Defined Conditions Testing Machine

Application:
The wire and cable smoke density tester conforms to GB/T17651.1~2-1998, IEC61034-1 ~ 2:1997 "Determination of Smoke Density of Cables and Optical Cables Burning Under Certain Conditions", which is used to measure the transmittance of smoke released by all insulated metallic conductor cables or optical cables used to transmit electrical energy or signals when burned horizontally under certain conditions.

Standard:
IEC 61034-1 ~2

Parameters:
