Influence of thermocycling on explosion hazard (detonation ability) of ammonium nitrate fertilizers Keywords: ammonium nitrate fertilizers, termocycling, standard methods, detonation ability, explosion hazard Influence of a termocycling on detonation ability of ammonium nitrate fertilizers of various manufacturers is investigated. Experiments were carried out in the conditions corresponding to a technique of Detonation Resistance Test of the European Union. Tests showed that the general legitimacies of influence of a termocycling on physical properties of samples exist, thus on detonation ability it is not possible to reveal the general legitimacies of influence of this procedure. It is established that the termocycling can lead both to improvement, and to deterioration of detonation ability of fertilizers with different composition at close granulometric structure and density. Despite it, explosion hazard of all studied samples, it agrees to the norms admitted to EU, remains at rather low level. Fertilizer of the Russian production appeared the best on safety level among all fertilizers in a condition of delivery, after a termocycling this fertilizer took a place in the middle of the list, having only a little conceded to the best foreign samples.  195212
