Smoke test equipment

densityautomaticindustrial

Smoke Box (Smoke Density Chamber) measures optical density of smoke generated from test sample when test sample of certain thickness is exposed to heat source(2.5W/c㎡, 25㎾/㎡ using by E 662 furnace) or fire in a chamber. This equipment 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 10 ㎾/㎡ to 50㎾/㎡ or 70kW/㎡ by user. In the test of NES 711, there are non-flaming test and flaming test in test conditions different from ASTM E 662. This test method is increasingly used in interior material of rolling stock, low power incombustible cable and interior film, etc. Standard • ASTM E 662 : Standard Test Method for Specific Optical Density of Smoke Generated by Solid Materials • BSI 6401 : British Standard Method for Measurement, in the laboratory, of the specific optical density of smoke generated by materials • ISO 5659-2 : Plastics-Smoke generation -Part 2: Determination of optical density by a single-chamber test • NES 711 : Determination of the Smoke Index of Products of combustion from Small Specimens of Material Features • Integrated body and 19” analysis rack (Saving space) • 17” touch screen panel type PC for the whole control and automatic testing • Air cylinder type movement to load sample or automatically open the up/down vent(highly resistant to pollution from test) • Coating of the test chamber convenient in cleaning and resistant to chemicals • Lock designed to close the chamber door at a time
