EN 13763-4:2003 (E)5IntroductionDuring usage on site, the insulation on the leading wires of electric detonators and the plastics tubing of shock tubenon-electric detonators can be subjected to many forces, including abrasive forces when drawn over roughsurfaces and/or cutting forces when drawn over a sharp edge. In the former, the plastics material is worn awaygradually by abrasion. In the latter, the sharp edge cuts directly into the material. This standard deals with theformer case by determining the ability of leading wire insulation/shock tube to resist the abrasive forces likely to beexperienced in normal use.1 ScopeThis European Standard specifies a method for determining the resistance to abrasion of plastics used asinsulating material for leading wires of electric detonators, or used as base material for the tubing of shock tubenon-electric detonators.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).EN 13857-1:2003, Explosives for civil uses - Part-1 Terminology.EN ISO/IEC 17025, General requirements for the competence of testing and calibration laboratories (ISO17025:1999).3 Terms and definitionsFor the purposes of this European Standard, the terms and definitions given in EN 13857-1:2003 apply.4 PrincipleThe test piece is subjected to abrasion by an abrasive surface, moving at a specified speed, while a specified loadis applied. For leading wires the time taken for the insulation to be penetrated is determined. For shock tubes thefunctioning of the shock tube after immersion in water is tested.5 Apparatus5.1 Abrasion test apparatus, as shown in Figure 1, comprising the following main components.SIST EN 13763-4:2004
