29、be to be used in non-electric detonator assemblies can be subjected to cutting forces when drawn over a sharp edge. In the former, the plastics material is worn away gradually by abrasion to cause failure of the insulation or tubing. In the latter, the sharp edge cuts directly into the material. Thi
30、s standard deals with the latter case by determining the ability of leading wire insulation/shock tube to resist the cutting forces likely to be experienced in normal use. 1 Scope This European Standard specifies a method for determining the resistance to failure of the plastic materials used in ins
31、ulation of leading wires of electric detonators, or the tubing of shock tube non-electric detonators, when drawn over a sharp edge under specified loading conditions. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications.

For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated
