EN-IEC 61123 is intended to define a procedure to verify if a reliability of an item/system complies with the stated requirements. The requirement is assumed to be specified as the percentage of success (success ratio) or the percentage of failures (failure ratio). This document can be used where a number of items are tested (number of trials performed) and classified as passed or failed. It can also be used where one or a number of items are tested repeatedly. The procedures are based on the assumption that the probability of success or failure is the same from trial to trial (statistically independent events). Plans for fixed trial/failure terminated tests as well as truncated sequential probability ratio tests (SPRTs) are included. This document contains extensive tables with ready-to-use SPRT plans and their characteristics for equal and non-equal risks for supplier and customer. In the case of the reliability compliance tests for constant failure rate/intensity, IEC 61124 applies.

This document explains how failure modes and effects analysis (FMEA), including the failure
modes, effects and criticality analysis (FMECA) variant, is planned, performed, documented
and maintained.
The purpose of failure modes and effects analysis (FMEA) is to establish how items or
processes might fail to perform their function so that any required treatments could be
identified. An FMEA provides a systematic method for identifying modes of failure together
with their effects on the item or process, both locally and globally. It may also include
identifying the causes of failure modes. Failure modes can be prioritized to support decisions
about treatment. Where the ranking of criticality involves at least the severity of
consequences, and often other measures of importance, the analysis is known as failure
modes, effects and criticality analysis (FMECA).
This document is applicable to hardware, software, processes including human action, and
their interfaces, in any combination.
An FMEA can be used in a safety analysis, for regulatory and other purposes, but this being a
generic standard, does not give specific guidance for safety applications.

The objective of any organization, as part of continual improvement, is to reduce the number of issues
(i.e. undesirable conditions, defects, failures) and to minimize their impact on quality, delivery
performance, and cost.
This includes having processes in place to detect and eradicate significant and recurrent issues, which
implies having well identified problems, a common understanding of their impact and associated root
causes, and having defined and implemented adequate actions so that these problems, including similar
issues will not happen again.
Propose a methodology to improve the way escapes and issues are managed, including communication
between all parties [e.g. engineering, Materials Review Board (MRB), manufacturing, manufacturing
engineering, supplier, customer] to reduce their impact, contain them as far upstream as possible, and
prevent recurrence (i.e. ensure the right measures are taken at the right location and at the right time).

This Standard defines the dependability assurance programme and the dependability requirements for space systems.
Dependability assurance is a continuous and iterative process throughout the project life cycle.
The ECSS dependability policy for space projects is applied by implementing a dependability assurance programme, which comprises:
•   identification of all technical risks with respect to functional needs which can lead to non-compliance with dependability requirements,
•   application of analysis and design methods to ensure that dependability targets are met,
•   optimization of the overall cost and schedule by making sure that:
   design rules, dependability analyses and risk reducing actions are tailored with respect to an appropriate severity categorisation,
   risks reducing actions are implemented continuously since the early phase of a project and especially during the design phase.
•   inputs to serial production activities.
The dependability requirements for functions implemented in software, and the interaction between hardware and software, are identified in this Standard.
NOTE 1   The requirements for the product assurance of software are defined in ECSS-Q-ST-80.
NOTE 2   The dependability assurance programme supports the project risk management process as described in ECSS-M-ST-80
This Standard applies to all European space projects. The provisions of this document apply to all project phases.
This standard may be tailored for the specific characteristic and constrains of a space project in conformance with ECSS-S-ST-00.

This International Standard gives guidance on the content and application of a dependability
case and establishes general principles for the preparation of a dependability case.
This standard is written in a basic project context where a customer orders a system that
meets dependability requirements from a supplier and then manages the system until its
retirement. The methods provided in this standard may be modified and adapted to other
situations as needed.
The dependability case is normally produced by the customer and supplier but can also be
used and updated by other organizations. For example, certification bodies and regulators
may examine the submitted case to support their decisions and users of the system may
update/expand the case, particularly where they use the system for a different purpose.

This International Standard describes the basic principles of root cause analysis (RCA) and
specifies the steps that a process for RCA should include.
This standard identifies a number of attributes for RCA techniques which assist with the
selection of an appropriate technique. It describes each RCA technique and its relative
strengths and weaknesses.
RCA is used to analyse the root causes of focus events with both positive and negative
outcomes, but it is most commonly used for the analysis of failures and incidents. Causes for
such events can be varied in nature, including design processes and techniques,
organizational characteristics, human aspects and external events. RCA can be used for
investigating the causes of non-conformances in quality (and other) management systems as
well as for failure analysis, for example in maintenance or equipment testing.
RCA is used to analyse focus events that have occurred, therefore this standard only covers a
posteriori analyses. It is recognized that some of the RCA techniques with adaptation can be
used proactively in the design and development of items and for causal analysis during risk
assessment; however, this standard focuses on the analysis of events which have occurred.
The intent of this standard is to describe a process for performing RCA and to explain the
techniques for identifying root causes. These techniques are not designed to assign
responsibility or liability, which is outside the scope of this standard.

This International Standard provides guidance on the application of various accelerated test techniques for measurement or improvement of product reliability. Identification of potential failure modes that could be experienced in the use of a product/item and their mitigation is instrumental to ensure dependability of an item. The object of the methods is to either identify potential design weakness or provide information on item dependability, or to achieve necessary reliability/availability improvement, all within a compressed or accelerated period of time. This standard addresses accelerated testing of non-repairable and repairable systems. It can be used for probability ratio sequential tests, fixed duration tests and reliability improvement/growth tests, where the measure of reliability may differ from the standard probability of failure occurrence. This standard also extends to present accelerated testing or production screening methods that would identify weakness introduced into the product by manufacturing error, which could compromise product dependability.
