Praćenje sadržaja stabilizatora jedna je od suvremenih i pouzdanih metoda koja se u svetu, a i kod nas, primenjuje za kontrolu kemijske stabilnosti i prognoziranje veka upotrebljivosti baruta. Radi ocene kemijske stabilnosti baruta domaće proizvodnje u radu su analizirani rezultati određivanja sadržaja stabilizatora u prirodno starenim jednobaznim barutima tipa NC i NCD i dvobaznim barutima tipa NGB i NGH. Pri tome su uporedno analizirani rezultati uzoraka iz kolekcija baruta iz Kragujevca (KB-1) i Zelenike (KB-2). Dobijeni rezultati ukazuju na znatno brži pad stabilnosti uzoraka baruta iz kolekcije KB-2, što se može objasniti značajnim uticajem klimatskih uslova. Osim toga, dobijeni rezultati potvrđuju uticaj mnogih faktora na kemijsku stabilnost baruta, kao što su: sastav, kvalitet sirovina, tehnološki postupak, oblik i dimenzije barutnog zrna i sl. / Monitoring of the stabilizer content is one of the modern and reliable methods in the world, and here also, which is used to control chemical stability and to predict the usage time of gun propellants. For the purpose of evaluation of gun propellants' chemical stability manufactured in our country, in this paper -we analyzed results from the content of stabilizer determination in naturally aged single base, NC and NCD type, and double base, NGB and NGH type of gun propellants. At the same time -we analyzed results from both collections of gun propellant samples, one from Kragujevac factory (KB-1) and the other from Zelenika factory (KB-2). Obtained results point that the stability decays faster for KB-2 collection samples, -which can be explained due to climate factors. Beside this influence, obtained results prove the influence of many factors on chemical stability of gun propellants: used components, quality of the ingredients, procedures of manufacture, shape and dimensions of gun propellant grains, etc.
