0 Introduction
0.1 Background and basic principles
Electronic initiation systems have been developed for use in civil blasting work. Detonators in these systems
normally have delay times which are far more accurate than conventional detonators with pyrotechnic delay, and
are claimed to facilitate better blasting results, e.g. in terms of better fragmentation, reduced ground vibrations, less
damage on remaining rock, etc.
From a safety and reliability point of view electronic initiation systems are more complex than conventional electric
and non-electric detonator systems, which results in new risk factors.
The aim of this Technical Specification is to reach negligible risks at least at the same applied safety and reliability
level as the corresponding standards for conventional electric detonators. This statement should be seen as a
general objective of the Technical Specification at a system level and not as a detailed guideline to judge the level
of acceptability for individual specific demands. However in some cases the standards for conventional electric
detonators referred to in this Technical Specification are applicable in various grades. In these cases the
requirement level for electric detonators have been adopted, possibly after some amendments if necessary.
This Technical Specification specifies a risk analysis procedure to be used to investigate the safety and reliability of
electronic initiation systems by identifying hazards and estimating the risks associated with the system.
The step in the risk analysis procedure, which refers to acceptability of risks, includes both references to testing
and evaluation methods, which apply where appropriate for the specific system. The Technical Specification also
stipulates levels of acceptability.
This structure of combining a general risk analysis procedure in combination with specific requirements related to
testing and evaluation as well as guidelines for evaluation specified in informative annexes has been chosen for the
following reasons:
• The use of electronic initiation systems are highly related to safety of human life and health as well as to
property. The safety and reliability of electronic initiation systems depends on a number of factors interacting,
which makes the systems complicated to evaluate in these respects. In this Technical Specification relevant risk
factors have been addressed to risks of unintended initiation, misfire and incorrect function.
• The need to consider safety and reliability for individual components of the system i.e. detonators,
firing/testing/programming units as well as overall system aspects including connection and set-up limits and
communication between the different components.
• The need for evaluation of safety-critical electronic hardware and software both in detonators and in
firing/testing/programming units.
• Manufacturers of electronic initiation systems have used significantly different design and system solutions in
order to fulfil acceptable safety and reliability criteria. The product development in the field is rapid. Therefore
the Technical Specification aims to be valid for different system solutions.
Considerable effort has been taken to refer to other parts of prEN 13763 for conventional detonators as far as
possible, specifying applicability of these tests as well as possible amendments in order to avoid redundancy and
inconsistency.
Possibilities for non-destructive testing using dummy detonators without explosive content, have been considered
as far as possible due to the high costs of electronic detonators.
0.2 Overview of an electronic initiation system
Electronic detonator systems can be fitted in two categories: non-programmable electronic detonators (or fixed
delay detonators) and programmable delay detonators. Programmable detonators can be programmed using one-
way data communication or two-way data communication. These categories are elaborated upon below:
Non-programmable detonators
This type of detonator does not require any data communications in order to ignite. The connection to the detonator
can be electrical or non-electrical. These detonators are normally numbered in such a way that the user recognizes
its intended delay time.
Programmable detonators
The delay time of these detonators is programmed prior to blasting, by either the testing unit or the firing unit. This
type of detonators usually require electrical connections to facilitate:
• One-way data communication: This implies that communication only take place to the detonator. No
information is received from the detonator. In these systems, it is vitally important that communications to the
detonator are robust.
• Two-way data communication: Communication takes place in both directions. Since feedback is received
from the detonator, it is possible to establish the state of the detonator. Useful information can include integrity
of the communications to the detonator, integrity of the initiation element, the firing capacitor voltage, results of
a self-test, etc.

Not all components illustrated below are necessarily required in an electronic detonator, at the same time, some
components may have been omitted. The purpose of the diagram is to familiarize the reader of this document with
some of the functions and components of an electronic detonator, such that the requirements and implications for
safe operations may be better understood.

C2 Firing capacitor. This capacitor supplies the energy required to fire the initiation element (IE). This capacitor may be
disconnected and/or shorted prior to blasting with the aid of SW1 and SW2. C1 and C2 may be separate capacitors, or they
may be combined. SW3 will be closed at the time of firing, after C2 had enough energy stored.
