Smoke Density Tester, developed by Rohm and Has Company in the United States, was originally developed in the 197Os based on the ASTM D2843 standard. Its theoretical basis is Billung's law, which involves direct flame impingement on the sample.
The tester measures the optical density of the smoke generated during combustion and determines the Smoke Density Rating (SDR). Currently.
it is widely used in accordance with international standards for the smoke density testing of PvC conduits and automotive interior materials.
Features:
Durable Teflon-Coated Chamber:
The test chamber is lined with Teflon, providing strong resistance to the corrosive effects of combustion-generated smoke, which significantly extends the lifespan of the equipment.
Clear Visibility Markers:
The bottom of the chamber features an "EXIT" sign in white letters on a red background. This allows test personnel to easily observe the clarity or blurriness of the sample through the transparent observation window.
Precision Light Sensing:
The tester uses an incandescent light source paired with a silicon photodiode as the light sensor, calibrated with cosine corection. Equipped with color filters, it effectively blocks UV and IR light that is not visible to the human eye, ensuring accurate color matching.
High-Pressure Flame Impact:
The main burner applies a flame to the test sample at a pressure of 276 KPA. An auxiliary burner is also included to subject any dripping material to additional flame impact, operating at a gas pressure of 138 KPA to ensure thorough combustion of molten droplets.
Advanced Data Display:
The standard test software provides light transmittance values every 15 seconds, generating a transmittance test curve. After the test, it calculates and displays the SDR (Smoke Density Rating) value, which represents the integral value of the smoke produced.
Comprehensive Test Reporting:
The software can compile and synthesize test reports from three sample groups, creating an SDR smoke density development curve. It also allows simultaneous comparison of SDR values from three tests, automatically determining compliance with testing standards.
User-Friendly Data Management:
Test data can be easily exported to a computer and connected to a printer for convenient report generation and printing, enhancing user accessibility and efficiency.
