European Foreword
This document (FprEN 16603-33-11:2018) has been prepared by Technical Committee
CEN/CLC/TC 5 “Space”, the secretariat of which is held by DIN (Germany).
This document (FprEN 16603-33-11:2018) originates from ECSS-E-ST-33-11C Rev.1.
This document is currently submitted to the Unique Acceptance Procedure.
This document will supersede EN 14607-6:2004.
Changes to EN 14607-6:2004 that was based on ECSS-E-30 Part 6A (25 April 2000) are:
• Complete edit to conform to the ECSS Drafting Rules for "ECSS Issue C standards"
• Implementation of ECSS Change Requests and harmonization the standard with
ISO in ECSS Revision 1 (2017)
• Change of the title from "Space engineering - Mechanical - Part 6: Pryotechnics" to
"Space engineering – Explosive subsystems and devices"
• Use of the more accurate term "explosive" rather than "pyrotechnics" in relation to
the subject components and systems
• Emphasis on reliability coupled with confidence level for performance properties
• Inclusion of detailed requirements for the different types of explosive device
• Emphasis on the requirement for properties of components to be agreed with the
end user before commitment to purchase.

This document has been developed to cover specifically space systems and will
therefore have precedence over any EN covering the same scope but with a wider
domain of applicability (e.g.: aerospace).
This document has been prepared under a mandate given to CEN by the European
Commission and the European Free Trade Association

Introduction
As any explosive item used for flight can function only once, it can never be fully
tested before its crucial mission operation. The required confidence can only be
established indirectly by the testing of identical items. Test results and theoretical
justification are essential for demonstration of fulfilment of the requirements. The
requirement for repeatability shows that product assurance plays a crucial role in
support of technical aspects.
The need for statistics requires that the explosive components used in the explosive
subsystem be tested and characterized extensively. The variability in components
requires that manufacturers prove to customers that delivered items are identical to
those qualified.
The failure or unintentional operation of an explosive item can be catastrophic for the
whole mission and life threatening. Specific requirements can exist for the items
associated with it. As all explosives where ever used are treated similarly, the same
requirements, regulations, practices and standards need to be applied to help
avoiding human error.

Scope
This Standard defines the requirements for the use of explosives on all spacecraft and
other space products including launch vehicles. It addresses the aspects of design,
analysis, verification, manufacturing, operations and safety.
This standard may be tailored for the specific characteristics and constraints of a space
project in conformance with ECSS-S-ST-00.

confidence level
3.2.2 arm plug receptacle
connector mounted on the skin of a spacecraft that can be connected to a Safe or Test

3.2.3 armed
status of an explosive subsystem when all the safety devices have been disabled and
which can be triggered
[Adapted from Dictionary of explosive related terms]
3.2.4 cartridge
explosive device designed to produce pressure for performing a mechanical function
A cartridge is called an initiator if it is the first or only
explosive element in an explosive train (see definition

3.2.7 deflagration
self-sustaining, exothermic decomposition reaction of an explosive substance, whose
apparent velocity is less than the velocity of sound in the substance and greater than
the speed of sound in air
It is generally accepted that the energy transmission
takes place via a mechanical compression wave. This
type of reaction is intermediary between combustion
and detonation. It differs from combustion through
the presence of a significant compression wave in the
surrounding environment.
[Dictionary of explosive related terms]
3.2.8 detonation
exothermic decomposition reaction of an explosive substance self-sustained by a
shock wave, whose velocity of propagation is greater than the velocity of sound in the
substance
The velocity of propagation is of the order of several
thousands of m/s.
[Dictionary of explosive related terms]
3.2.9 detonator
initiator whose function is to transform external energy directly into a shock wave
strong enough to detonate a secondary high explosive
External energy can be, for example, mechanical,
electrical and thermal.
[Dictionary of explosive related terms]
3.2.10 electro-explosive device
device containing some reaction mixture that is electrically initiated
NOTE 1 The output of the initiation is heat, shock or
mechanical action.
NOTE 2 The reaction mixture can be explosive or pyrotechnic.
[Dictionary of explosive related terms]
3.2.11 end-user
person who or organization that actually uses a product
NOTE 1 The end-user need not to be the owner or buyer.
NOTE 2 In the context of this standard the end user is
generally the first level customer.
3.2.12 energetic material
material consisting of, or containing, an explosive, oxidizer, fuel, or combination of
them, that can undergo, contribute to, or cause rapid exothermic decomposition,
combustion, deflagration, or detonation

3.2.17 explosive subsystem
collection of all the explosive trains on the spacecraft or launcher system, and the
interface aspects of any on-board computers, launch operation equipment, ground
support and test equipment and all software associated with explosive functions
3.2.18 fail operational
mission capable after one failure
Maintaining operational conditions after one failure
and safety conditions after a second independent
failure is referred to as "Fail operational – Fail safe".
3.2.19 fail safe

Maintaining safety following two independent
failures is referred to as "Fail safe – Fail safe".

E.g. pyrotechnic igniters for solid propulsion
applications, gas generator for inflatable structures.
3.2.21 initiator
basic component located upstream of an explosive train, from which originates a
transformation of mechanical, electrical or optical energy, the effect produced being a
combustion, deflagration or detonation.
NOTE 1 It contains a small quantity of an energetic material.
