EN 13631-4:2002 (E)41 ScopeThis European Standard specifies a method for determining the sensitiveness to impact of explosives.2 Normative referencesThis European Standard incorporates by dated or undated reference, provisions from other publications. Thesenormative references are cited at the appropriate places in the text, and the publications are listed hereafter. Fordated references, subsequent amendments to or revisions of any of these publications apply to this EuropeanStandard only when incorporated in it by amendment or revision. For undated references the latest edition of thepublication referred to applies (including amendments).prEN 13857-1:2001, Explosives for civil uses – Part 1: Terminology.EN ISO 683-17:1999, Heat-treated steels, alloy steels and free-cutting steels – Part 17: Ball and roller bearingsteels (ISO 683-17:1999).EN ISO 4957, Tool steels (ISO 4957:1999).EN ISO/IEC 17025, General requirements for the competence of testing and calibration laboratories (ISO/IEC17025:1999).3 Terms and definitionsFor the purposes of this European Standard, the following terms and definitions apply in addition to those given inprEN 13857-1:2001:3.1reactionoccurrence of report or flame3.2drop heightdistance between the uppermost part of the impact device and the lower face of the striking head immediatelybefore the drop3.3impact energyenergy of the drop weight immediately before impact, calculated by multiplying the mass of the drop weight by thedrop height and by the acceleration due to gravityNOTEFor practical purposes, the acceleration due to gravity is rounded to 10 m/s² so that, for example, with a drop weightof mass 1 kg and a drop height of 500 mm the impact energy is assumed to be 5 J.3.4sensitiveness to impactlowest impact energy at which a reaction is obtained from at least one out of six tests4PrincipleA weight of known mass is dropped onto a sample of the explosive which is confined in a way that during theimpact of the weight no significant friction is applied to the explosive.
