DIN 4102 Building Material Flammability Testing Equipment / Smoke
Density Fire Tester
Application
Suitable used for measuring the somke-producing characteristic of
building material under controlled condition of combustion or
decomposition, and also can be used for other plastics.
Standards
ASTM D 2843,DIN 4102
Specification
1. Maximum smoke density (MSD) and smoke density (SDR) for the
specimen: 0-100% continuously measurable and automatically
calculated;
2. With the standard optical correction error of not more than 3%;
each device is equipped with three standard filters, proof of light
source data, representative
3. Bunsen lamp working pressure (210 ± 5) KPa;
4. Bunsen lamp on the sample to impose a flame 4min;
5. Automatic timing, automatic ignition, automatic smoke; luminous
flux can be phased linear calibration test data
more acurrate;
6. Touch Screen:
a. Size: 5 inch effective display size 11cm wide 6.28cm;
b. Resolution: 800 * 480

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.
