Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 24917 was prepared by Technical Committee ISO/TC 20, Aircraft and space vehicles, Subcommittee

5 Testing philosophy
5.1 Objectives, tasks and principles of launch vehicle and rocket unit experimental
optimization
5.1.1 Experimental optimization is one of the methods of verification which guarantees that all
characteristics of the space launch vehicle (SLV) meet the requirements of the statement of work (SOW). The
SLV is tested in the structure of the space rocket complex (SRC).
Experimental optimization of SLV, launch vehicle (LV) units and unit components includes ground
experimental optimization phases and flight test. The complete test programme for launch vehicles, upper
stage, encompasses development, qualification, acceptance, pre-launch validation and follow-on operational
test and evaluations. The test programme encompasses the testing of progressively more complex
assemblies of hardware and computer software. Generally the SLV experimental optimization structure may
be represented as a scheme (see Figure 1).
5.1.2 The major objective of ground experimental optimization is to optimize and verify the SLV preparation
technology for launch and launch itself, preliminarily verify and evaluate implementation of the project-
specified parameters and characteristics, operation and interaction patterns of all SLV components and SLV
as a whole when the operation conditions are being simulated (or under effect of these conditions).
5.1.3 The major objective of flight test is to comprehensively check the SLV serviceability and confirm the
SOW-specified requirements for the space rocket complex under real operation conditions.
5.1.4 One of the major objectives of SLV [upper stage vehicle (USV)] ground experimental optimization is to
achieve the SOW-assigned levels of reliability and safety indexes before flight test commencement to be
confirmed during the flight test. The reliability and safety index levels are normalized in the reliability
assurance programme (RAP) and the safety guarantee programme (SGP), the latter including environment
safety guarantee.
5.1.5 The main objectives of experimental optimization of SLV, LV units and SLV unit components are as
follows:
a) verification of unit structure strength, rigidity, confirmation of rocket module parameters, verification of
equipment mechanical loading regimes;
b) breadboarding;
c) optimization of technological cycle of preparing SLV for launch and launch itself;
d) comprehensive verification of rocket unit systems functioning during launch and propulsion system
operation in the assigned regimes;
e) verification of the ground technical means/launch vehicle compatibility;
f) optimization of SLV interfaces [LV, upper stage vehicle, spacecraft (SC)];
g) experimental confirmation of the correctness of adopted engineering solutions;
h) verification of the sufficiency of measuring aids and TM data processing techniques;
i) individual optimization of all SLV components;
j) verification of operation convenience;
k) personnel training.

ISO 24917:2010(E)
5.1.6 The problems to be solved while testing specific LVs are identified according to the engineering make,
assigned characteristics, LV optimization degree, design novelty (modification scope), dedicated operation
conditions change and are presented in the test programmes.
The environmental factors specified in SOW tests are intended to be imposed sequentially, rather than in
combination. Nevertheless, features of the hardware design or of the service environments may warrant the
imposition of combined environments in some tests, e.g. combined shock, vibrations. In formulating the test
requirements in these situations, a logical combination of environmental factors should be imposed to
enhance test effectiveness.
5.1.7 Organization and order of conducting the experimental optimization are determined by the
comprehensive experimental optimization programme.

ISO 24917:2010(E)
5.1.8 In order to meet the assigned LV (USV) characteristics requirements, the supplier plans experimental
optimization.
5.1.9 The comprehensive experimental optimization programme is developed in accordance with the LV
(USV) hierarchical structure. The main starting documents for developing the SLV ground test programme are
the statement of work, the preliminary project and the reliability assurance programme.
5.1.10 The SLV comprehensive experimental optimization programme is a common system of independent,
particular programme-technical documents, identifying the individual test objectives and scope, establishing
the criteria of USV or LV completeness and readiness for transferring to higher test levels.
The test sequence, scope and object, controlled characteristics, types of test and test phasing in the course of
LV (rocket unit) development are assigned by the LV (rocket unit) manufacturers-contractors in the
comprehensive experimental optimization programme, other test programmes.
5.1.11 The LV (USV) ground test programme (GTP) is planned and arranged on the basis of the following
principles:
a) system approach to the optimization planning with a detailed coordination of all types and phases of
optimization test; absolute assurance and confirmation of the assigned characteristics of the SRC items
during ground test; use of results of optimizing the complex systems functioning as a component of other
complexes;
b) fulfilment of the major optimization work scope applying test facilities (benches, rigs, models, etc.) before
starting ready-made (standard) LV (USV) test under real operation conditions (full-scale test);
c) confirmation of all-round interaction of all SLV components and demonstration of their functioning
reliability under full-scale conditions, as well as conduct of that part of optimization applying test means
which cannot be technically performed or are economically inexpedient within the assigned time during
flight test, and on the basis of the following provisions:
1) determination of nomenclature and characteristics of modified and newly developed test benches
(rigs) on condition that they would assure fulfilment of the planned test types and scopes;
2) use (if necessary with updating) of test facilities, benches and technological fittings developed for
previous items;
3) assessment of the sufficiency and correctness of selecting equipment, control-measuring aids,

evaluating the operation reliability; use of the capability of multiple starting the systems and
assemblies under ground conditions for conducting multiple optimization tests (including different test
types) applying limited number of items;
5) complex components control during the test;
6) all-round coordination of all test types of items at LV (USV) hierarchical structure levels with due
regard for the values of tested characteristics, measurement precision, reproducibility of bench test,
as well as test completeness requirements;
7) feasibility study of the test tasks, types and scopes stipulated in the comprehensive experimental
optimization and flight test programmes (FTP);
8) satisfaction of the active normative document requirements (including standards for test types and
norms, technical state review, information exchange, industrial safety measures, etc.);
9) planning of experimental works to optimize new technological processes including the planning of
optimization technology for assuring the cleanness of internal cavities of propulsion system tanks,
pneumatic/hydraulic systems, internal volume of the integration-protection block;

systems for making up bench items;
14) multiple use of material (bench items) designed for optimization (testing) at the expense of its
updating and replenishment;

(including environmental safety), with due regard for data obtained while analysing the types of
critical failures, their consequences and critical elements;

either already performed or currently being carried out, as well as the list of actions and the devices
providing the exception of space debris formation during the SLV launch;
17) test conduct under real complicated operation regimes, and non-standard situation simulation;

publication of corresponding opinions as to clearing the modified assembly (system) for further higher
level test;
