TY - CONF A1 - von Oertzen, Alexander T1 - New Standardisation Tasks under the European Explosives Directive: Electronic Detonators, On-site Mixed Explosives N2 - Several decades have passed since the initial drafting of the European standards for explosives subject to European Directive 2014/28/EU, and this field as experienced some substantial technical innovations. While at the turn of the millenium the concept of electronic detonators had just been conceived, and it is mentioned in a Technical Specification, today electronic detonators exist in many variants, also regarding communication means between shotfirer and the detonating cap. Questions regarding safe functioning and prevention of inadvertent ignition have to be asked in a quite different way, where delicate electronic circuits are used, and where information is transmitted by radio waves. In addition, the safety of functioning is partly found in software components and the corresponding standards need to be reviewed thoroughly on these grounds. A different but in recent times more and more popular technology, is the on-site production of explosives, being mostly emulsion explosives, ANFO, or combined products. Also here software in the machinery is starting to play an important role. The on-site produced explosive must fulfil safety requirements and has to be, in addition, quality controlled. This cannot solely be left to the hopefully proper design of the software and machinery, but needs to be made accessible to verification. Since this area seems broader in approach, it is not going to be addressed by a new standard. The state of the art technology shall be described in a Technical Specification with a perspective from requirements of the above mentioned European Directive.

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.
