The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 0.7 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 0.7 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.1 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00016 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.18 SJR: 0.313 SNIP: 0.6 CiteScore™:: 1.6 H-Index: 16

SINOPSIS

An insensitive munition (IM) is one that will not detonate under any conditions other than its intended mission to destroy a target. This is the common definition of insensitive ammunition. One part of such ammunition is the energetic propellant charge. Since it is possible to initiate the detonation of each energetic mass, the test methods for the characterization of "low" sensitive gun propellants are presented in this paper.
The following points have to be taken into account for the safety tests:
1.) high temperature, fire, blast (shock wave), fragments, and storage life during the storage of the propellant and the ammunition;
2.) sufficient mechanical properties against pressure, acceleration, the so-called grain pressure, and propellant temperature during the mission of the gun propellant in the weapon.
Therefore, two different types of safety tests are taken into consideration: one for the capability to detonate or deflagrate based on the chemical composition, and the other based on the mechanical behavior of the granular propellant charge.
Besides the common tests (shaped charge jet, fast cook-off, slow cook-off, sympathetic detonation tests, etc.), the different loads related to the propellant charges and grains are pointed out and discussed with respect to burning behavior and safety. The results of different tests conducted with several propellants are presented and conclusively discussed.
Although the test methods between France and Germany are partly distinct, the determined reaction types are comparable. A highly sensitive behavior with the reaction I type (i.e. detonation) is observed for the nitrocellulose propellant D6040 according to the French as well as the German test methods. In the case of double- and triple-base propellants (F5600, L5460, N6540), behaviors corresponding to reactions of the III to IV types are determined.
