Nbs Smoke Density Chamber / Smoke Toxicity of Materials ISO 5659 ASTM E 662

Introduction:

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/cm2, 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 10 kw/m2 to 50kw/m2or 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.

International standards:
1. ISO5659
2. ASTM E 662

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
• Indication of transmission rate and smoke density with improved accuracy
• Chamber preheat system to facilitate test with more accuracy
• Safety blow-out panel system to protect user when pressure is sharply increased during test
• Port, heated filter, and heated line to measure toxic gases
• Manometer gauge with increased accuracy by using the MFC(Mass Flow Controller) and DPT(Differential Pressure Transducer) enabling auto leakage test
• Portable water cooling system without need for waterworks and plumbing when using the Heat Fluxmeter (for ISO 5659)
• Load cell with increased accuracy to measure mass loss rate in ISO 5659 test
• SB 2005 DAQ(Data Acquisition) Program to control the use of touch screen panel PC
