Bergmann – Junk

Apparatus for determining the thermal stability of nitro-cellulose and other nitrocompounds, single and double base propellants according to the Bergmann-Junk Test at 120 or 132°C (STANAG 4178 5C).

The Bergmann-Junk Test is based on quantitative determination of nitrogen oxides evolution during thermal decomposition of the sample.
