Space engineering - Explosive subsystems and devices

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.

European Foreword
This document (EN 16603-33-11:2019) has been prepared by Technical Committee
CEN-CENELEC/TC 5 “Space”, the secretariat of which is held by DIN.
This standard (EN 16603-33-11:2019) originates from ECSS-E-ST-33-11C Rev.1.

This European Standard shall be given the status of a national standard, either by

publication of an identical text or by endorsement, at the latest by October 2019, and

conflicting national standards shall be withdrawn at the latest by October 2019.

Attention is drawn to the possibility that some of the elements of this document may

be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible

for identifying any or all such patent rights.
This document supersedes 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 prepared under a standardization request given to CEN by
the European Commission and the European Free Trade Association.
This document has been developed to cover specifically space systems and has
therefore precedence over any EN covering the same scope but with a wider domain
of applicability (e.g. : aerospace).
According to the CEN-CENELEC Internal Regulations, the national standards
organizations of the following countries are bound to implement this European
Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark,

Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece,

Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands,

Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden,
Switzerland, Turkey and the United Kingdom.

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.

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

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
NOTE 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

them, that can undergo, contribute to, or cause rapid exothermic decomposition,
combustion, deflagration, or detonation

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
NOTE 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

design property of a subsystem, or part of it, which remains safe after one failure

NOTE Maintaining safety following two independent
failures is referred to as "Fail safe – Fail safe".
3.2.20 gas generators
explosive devices that produce a volume of gas or exothermic output or both
NOTE 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.
