ISO 5659-2 NBS Cable and Wire Smoke Density Testing Equipment
Introduction:
Smoke Box (ISO 5659-2 NBS Cable and Wire Smoke Density Testing Equipment) measures the optical density of smoke generated from the test sample when a test sample of a certain thickness is exposed to a heat source (2.5 W/cm2, 25kW/m2 using by E 662 furnace) or fire in a chamber.
ISO 5659-2 NBS Cable and Wire Smoke Density Testing 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/m2 or 70kW/m2 by user.
In the test of NES 711, there are non-flaming tests and flaming tests in test conditions different from ASTM E 662.
This test method is increasingly used in interior material of rolling stock, low-power incombustible cable 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
Application:

Features:
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 a sample or automatically open the up/down vent(highly resistant to pollution from the test).
4. The coating of the test chamber is convenient for cleaning and resistant to chemicals.
5. A lock is 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 the user when pressure is sharply increased during the 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 the need for waterworks and plumbing when using the Heat Fluxmeter (for ISO 5659).
12. Load cells 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.
