Product Description

NBS Smoke Density Chamber, ASTM E662, ISO 5659 fire resistance

the introduction of  iso 5659:
NBS Smoke Density Tester measures optical density of smoke generated from test sample when test sample of certain thickness is exposed to heat source(2.5W/m2, 25kw/m2 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 10kw/m2 to 50kw/m2 or 70kW/m2 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. 

the standard we can meet:
• 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
