Armaments and military equipment belong to a group of products that are extremely demanding in terms of: production safety, use, environmental impact, reliability, and performance. The purpose of the article is to analyze the impact of metrological confirmations of dial sensors on the safety of production and use of ammunition and rockets. Reference was made to two components of various products: the shell for 5.56 x45 mm steel-core and the engine hull for the Lightning Portable Anti-Aircraft Rocket Set. The main research problem was contained in the questions: does the metrological confirmation status of a measuring instrument/checker have an impact on the safety of the manufactured product and what impact does a dial gauge/sensor gauge have on the production of ammunition and rockets? The research hypothesis was defined as follows: measuring with a dial gauge/sensor gauge the components of a product has an impact on the safety and quality of armaments and military equipment. With the research methods in mind, a dial sensor test was carried out on an automatic ICM 100 IP bench used for inspecting sensors, among other things, and the results obtained were compared with the requirements of the Polish standards and the internal instruction. Analyses were carried out of: defense standards, available documents, and quality and environmental requirements for weapons and military equipment. The principles of metrological supervision according to PN-EN ISO 10012:2004 - Measurement and measurement equipment management system are also presented. As a result of the study, the author notes that the use of dial sensors that meet metrological requirements eliminates errors related to: the thickness of the shell wall, the thickness of the bottom of the primer seating, and guarantees the verification of the correctness of runout on the hull of the rocket motor. It has a significant impact on the correct measurement of product elements and obtaining the correct parameters at each stage of production and inspection of elements - in accordance with the technical documentation, thus affecting the safety of the product. Both the shell for 5.56x45 [mm] ammunition and the hull of the PPZR Piorun engine are a significant link in the stability of the entire product, on which its efficiency and reliability depend. In the author’s opinion, all research and analysis of the intertwined areas of product quality and safety are necessary in order to: improving production processes, reducing the cost of subsequent complaints, and, above all, ensuring the safety of equipment users.
