Nbs Smoke Density Chamber ISO 5659-2 Flammability Testing Equipment
the introduction of ISO 5659 tester:
Nbs Smoke Density Chamber ISO 5659-2 Flammability Testing Equipment measures optical density of smoke generated from test sample when test sample of certain thickness is exposed to heat source(2.5W/cm2, 2KW/m2 using by ASTM E 662 furnace) or fire in a chamber.
Using ISO 5659 conical radiant heat furnace, we can change the heating condition from 10KW/m2 to 5KW/m2 or 70kW/m2 according to different requirements.
the standard we can meet:
• ASTM E 662: Standard Test Method for Specific Optical Density of Smoke Generated by Solid Materials
• ISO 5659-2: Plastics-Smoke generation -Part 2: Determination of optical density by a single-chamber test
the mian features about this product:
1. Integrated body and 19" analysis rack (Saving space)
2. 17" touch screen panel type PC for the whole control and automatic testing
3. Air cylinder type movement to load sample or automatically open the up/down vent(highly resistant to pollution from test)
4. Coating of the test chamber convenient in cleaning and resistant to chemicals
5. Lock designed to close the chamber door at a time
6. Indication of transmission rate and smoke density with improved accuracy
7. Chamber preheat system to facilitate test with more accuracy
8. Safety blow-out panel system to protect user when pressure is sharply increased during test
9. Port, heated filter, and heated line to measure toxic gases
10. Manometer gauge with increased accuracy by using the MFC(Mass Flow Controller) and DPT(Differential Pressure Transducer) enabling auto leakage test
11. Portable water cooling system without need for waterworks and plumbing when using the Heat Fluxmeter (for ISO 5659)
12. Load cell with increased accuracy to measure mass loss rate in ISO 5659 test
13. SB 2005 DAQ(Data Acquisition) Program to control the use of touch screen panel PC
