When the thickness of the test sample was placed in a certain heat 25KW/m2, or cabinets open flames, smoke density chamber can measure their smoke density. The instrument applies to ASTM E 662, BS6401, ISO 5659, NES 711, NEPA 258 etc. Use the cone radiation furnace which in the ISO 5659, the user can arbitrarily adjust the heating condition by 10kw/m2 to 50kw/m2.The test is increasingly being used in vehicle interior materials and other low-power, non -flammable cables tests.
Standard
ASTM E 662: Standard test method for specific optical density of smoke generated by solid materials (The radiation cone is optional)
BSI 6401: British Test Standard for specific smoke density indexISO 5659-2: Plastics-Smoke generation-Part2: Determination of optical density by a single-chamber test
NES 711: Determination Of The Smoke Index Of The Products Of Combustion From Small Specimens Of Materials
Features
• Integrated design, 19 "analysis and control panel number
•19 "industrial computer full control and the test can be done automatically
• To carry the sample through moving the cylinder or automatically opening the top and bottom exhaust port (Highly resistant to pollution)
• The coating of test box is easy to clean and resistant to chemical corrosion
• Lock design is easy for one-time to close the door
• Accurate display of smoke transmittance and smoke density
• Preheating system of the chamber can accelerate the test and the accuracy is higher
• When the furnace pressure increased rapidly during the test,the security blasting and tablet system can ensure the safety of users
• Using MFC (mass flow controller) and DPT (pressure sensor) can improve the accuracy of pressure gauge and automatically let out the test
• Using heat time (ISO 5659) without water pipes, portable water cooling system can complete the test on their own
• In the ISO 5659 test, the load sensor can accurately measure the mass loss rate (Optional)
• Equipped with a DAQ data acquisition program
