EN 16701:2014

Energetic materials for defence - Safety, vulnerability - Friability

This European Standard describes a method for assessing the deflagration to detonation transition (DDT) risk of an explosive material subjected to a mechanical threat.
Testing applies to any compact solid explosive material.

Energetische Wehrmaterialien - Sicherheit, Verwundbarkeit - Sprödigkeit

Matériaux énergétiques de défense - Sécurité, vulnérabilité - Friabilité

La présente Norme européenne décrit une méthode d'évaluation du risque de transition de la déflagration vers la détonation (TDD) d'une matière explosive soumise à une agression mécanique.
L'épreuve s’applique à toute matière explosive solide compacte.

Energetski materiali za obrambo - Varnost, ranljivost - Krhkost

Standard EN 16701 opisuje metodo za oceno tveganja prehoda iz deflagracije v detonacijo (DDT) eksplozivnega materiala, na katerega vpliva mehanska grožnja. Preskušanje se uporablja za poljuben kompakten trden eksplozivni material.

A more complete description is given in French Standard NF T 70–714. It is possible to check the suitability of the combustion chamber using (9 ± 0,1)g of double - base propellant with the following characteristics: 5,225 kJ/g formed as square pellets: 8 mm × 8 mm x 0,8 mm. With this sample it is necessary to obtain: — Pmax = (80 ± 5) MPa; — (dP/dt)max = (14,5 ± 1,0) MPa/ms; in compliance with the specifications regarding: — the geometry of the combustion chamber; — the acquisition and processing of the signal; — the definition of the ignition mechanism. These specifications are stated in French Standard NF T 70–714. These results are obtained with a closed vessel whose combustion chamber has a constant volume of approximately 130 cm3 (see Figure C.1). 4.4 Measurement apparatus 4.4.1 Measurement of the impact velocity The impact velocity is measured 1,55 m from the impact disk using, for example, two optical barriers that are 10 cm away and connected to a chronometer (see layout in Annex A). This velocity shall be measured at ± 1 m/s. 4.4.2 Recording of the pressure when burning inside the closed vessel In general, reference should be made to French Standard NF T 70–714 for the choice of elements for the measurement chain (pressure sensor, charge amplifier, numbering and memory storage apparatus).
