Bergmann Junk Test Apparatus

Bergmann-Junk and Bergmann-Junk-Siebert tests are traditional methods for determination of chemical stability of nitrocellulose, single and double based smokeless powders, rocket fuels and nitro compounds. Testing apparatus is provided as a modular solution for easy set up for required testing standard.

Bergmann-Junk Tests are reliable quantitative methods with high re producibility. These tests are fast, affordable and require no additional laboratory skills. Standard consumable materials further extend its accessibility by eliminating expensive, standard test papers.

Unstable behaviour of nitrocellulose and NC based energetic materials is associated with the liberation of heat and gaseous decomposition products, which also contain nitrogen oxides (NO,). Exposition of the sample to a higher temperature increases its decomposition rate.

Bergmann-Junk based testing methods were developed to evolve NO, in defined conditions and to absorb it in exact apparatus. Further quantitative analysis provides reliable and reproducible values of nitrogen oxides in decomposition gases. Further consideration of these values provides an overview of material stability and their lifetime.

Bergmann-Junk method is usually combined with Heat test (Methyl Violet Test), Abel Heat Test, Vacuum Thermal Stability Test and HPLC. The result of Bergmann-Junk Test is presented as a volume (in ml) of titration agent of given concentration per gram of the sample or as weight (in mg) of nitrogen per gram of the sample.
