Product Description

Introduction:

NBS Smoke Index Test Device as proved to be one of the most versatile fire testing instruments since its inception in the 1980s.

It is the most widely accepted apparatus for the measurement of smoke from burning materials and measures specific optical density under flaming and non-flaming conditions. It is also used for the extraction of toxic gas.

NBS Smoke Index Test Device is satisfied with standards (ASTM E 662, BS6401, ISO 5659, NES 711, NEPA 258, etc).

Using ISO 5659 conical radiant heat furnace, we can change the heating condition from 10KW/m2 to 5KW/m2 according to user's requirements.

In the test of NES 711, there are non-flaming test and flaming test in test conditions different from ASTM E 662.
The main principle is to measure smoke density in a particular space, cable or material produced under specific conditions of combustion or 713 radiation. The smoke will cause the beam attenuate when passes through the smoke, the light transmittance be use to calculate ratio of the optical density and smoke density. The smoke density chamber is designed according to ISO5659 standard. It has a conical radiant furnace, heat flux can be up 50 kW / m2, and laterally positioned sample, it also can test the sample mass loss rate.
