The main content of the article is to provide conditions for determining the content of Bor (B) in raw materials and pyrotechnic products BH-NLP17 by instrumental analysis using ICP-OES emission spectroscopy system. The author has evaluated the influence of pH on the analysis results as well as selected the optimal sample digestion method using concentrated HNO3. In addition, the assessment of measurement uncertainty helps confirm the correctness of the analysis method. The research results have helped to select the right type of raw materials, control the quality of raw materials and final products, thereby contributing to stabilizing and improving the quality of production, contributing to the production of artillery shell fuses in particular and the defense industry in general.
