Frequently Asked Questions
Q1: What is this equipment used for?
A1: This tester measures smoke density emitted by building materials and plastics during combustion or decomposition. It helps manufacturers assess fire safety performance and comply with building code requirements.
Q2: What standards does it comply with?
A2: It meets ASTM D2843 and DIN 4102 requirements for smoke density testing of building materials and plastics.
Q3: What materials can be tested?
A3: Building materials such as wall panels, insulation, flooring, and other construction products, as well as various plastic materials.
Q4: How does the test work?
A4: A specimen is exposed to a Bunsen burner flame for 4 minutes. A photoelectric system measures light transmittance through the smoke, automatically calculating smoke density values.
Q5: What parameters does it measure?
A5: Maximum Smoke Density (MSD) and Smoke Density Rate (SDR) are continuously measured and automatically calculated over a 0–100% range.
Q6: What gas supply is required?
A6: The instrument requires 95% propane gas or gas of equivalent purity, which must be supplied by the customer.
Q7: Is data export supported?
A7: Yes, the touch screen controller includes an RS232 communication interface for data export and integration with external systems.
What is smoke density test?
This test measures the amount of smoke given off by a material that is burning or smoldering. The material is tested when it begins to smolder and again when a flame source is added. The smoke density is between 0 (no smoke generated) and 800.
