TY - CONF A1 - Krebs, Holger A1 - Hasenfelder, Uta A1 - Schäfer, Diana A1 - von Oertzen, Alexander T1 - Investigations of non-electric detonators and conclusions N2 - More than 5 million non-electric detonators are used annually in Germany for blasting operations. The relative usage of non-electric detonators amounts to about 50% of all civil blasting operations in Germany. BAM, as the notified body for explosives in Germany, tests non-electric detonators for the purpose of EU-type approval under the civil explosives directive, but also in the context of general investigations, e.g. when misfiring occurs. BAM has all facilities to test these detonators according to the European standard EN 13763. The presentation will cover the test facilities of BAM and address some issues of delay time accuracy. Several advantages and disadvantages of the non-electric ignition system will be discussed in the context of case investigations, and conclusions for mining operations and the advoidance of misfiring will be drawn.

The NBs perform the EC-type examimtions for all sorts of explosives (cartridged explosives, detonators, aso.) following the test instructions from European harmonised Standards. Through applying the Standards the essential safety requirements set out in Directive 93/15 are checked. When a positive result is achieved during type testing, a high level of safety during transport, storage, and use can be assumed. Even though the tests are described in the Standards with high detail, there may still occur differences in testing between different test houses. Whether such differences lead to still agreeing, or perhaps to disagreeing results in type testing, can only be determined by so called Round-Robin tests (RRT). These are «inter-laboratory» comparisons and constitute an essential pari of proficiency testing for each NB, respectively test laboratory. BAM as a Notified Body will be shortly introduced, and the presentation will then concentrate on recent RRT done with explosives. Results, difficulties, and conclusions will be presented.

This is particularly evident for electronic detonators and electronic firing systems, and the EU commission agreed to initiate a standardisation initiative, also noting that the currently existing document on electronic detonators is “only” a Technical Specification (CEN/TS). This paper addresses the current activities in the area of standardisation. The EU is about to launch a formal standardisation request to cover the most recent technological developments not addressed by the current standards. The request would also include various adjustments of references to the new Directive for civil explosives, and in addition the task of developing a Technical Specification for on-site mixed explosives and corresponding manufacturing units. The latter has been included to address the nowadays frequently found mobile production on the basis of ammonium nitrate prills or emulsions.
