This document presents methods for determining the critical value of the response variable and the minimum detectable value in Poisson distribution measurements. It is applicable when variations in both the background noise and the signal are describable by the Poisson distribution. The conventional approximation is used to approximate the Poisson distribution by the normal distribution consistent with ISO 11843-3 and ISO 11843-4. The accuracy of the normal approximation as compared to the exact Poisson distribution is discussed in Annex B.

This document specifies a fundamental principle on grid square statistics and includes the following: — To define or specify a set of methods that can be recommended as the standard method to enable policy decisions based on common recognition from grid statistics produced with different grid square reference system standards in different countries and areas that can have different geographic coding systems with different geometric shapes. — To standardize methods to accommodate the conversion calculation among grid statistics with different grid square reference systems having different geometric shapes by employing prorating method based on the grid areas as well as the method to calculate the approximation errors, for exchanging the converted grid statistics. Spatial expressions other than grid square also exist, but this document does not apply to the spatial expressions other than grid square. NOTE Clause 4 and Clause 5 define grid square statistics and specify some methods to generate grid square statistics. REF Section_sec_6 \r \h Clause 6 recommends conversion methods between grid square statistics generated based on different grid square reference systems.

IEC 62508: 2025 provides guidance on current knowledge and practice concerning dependability in an operational environment, in terms of the humans, teams and organizations involved in conducting the work. It is part of a suite of IEC standards that are intended to address the dependability of both the technical and human elements of equipment and organizations.
This document describes the human elements of a typical operational system, and the importance of those elements to overall dependability. It also describes the means of assessing how well these elements are functioning, and general concepts on how the reliability of humans can be improved. These elements typically include the individual workers, the groups or teams into which they are organized, the interfaces between humans and technical systems, and the overall organization.
The following guidance is applicable to any industry that depends on human-systems interactions involving the technology, software, or systems of work required to support the production and safety objectives of an organization. This document primarily addresses complex technical systems, but some parts are also applicable to the manufacturing of industrial and consumer products. Principles for design of the human-machine interface (usability) are described, and further information can be found in the technical literature and in relevant product standards. Although this document does not specifically cover worker health or safety, the application of this document can raise related issues, particularly in process safety, which is closely associated with system reliability.
This second edition cancels and replaces the first edition published in 2010. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) The emphasis on user-centred design in the previous edition was reduced in favour of a greater emphasis on human dependability in an existing operational environment.
b) The emphasis on human error and error-rate determination methods was reduced in favour of a greater emphasis on means of providing organizational support for the workforce in their execution of required tasks.
c) Where appropriate, discussions of human factors in an operational environment were aligned with current theory, terminology and practice.

IEC TR 63162:2025, which is a Technical Specification, provides failure rates at reference conditions for electric components, considering reference conditions defined in IEC 61709.
Reference conditions are useful since they provide a known standard basis from which failure rates can be modified to account for differences in environment from the environments taken as reference conditions.
To perform reliability prediction, which is described in IEC 61709:2017, Annex C, failure rates, together with assumptions and limitations, are used.
IEC 61709 does not provide failure rates for components, but only provides models that allow failure rates obtained by other means to be converted from one operating condition to another operating condition.
This document provides generic failure rates considering those contained in the list of selected sources, calculated at reference conditions, as defined in IEC 61709. In fact, although models are different, calculated values at reference conditions do not appear to be so different, hence allowing a consistent converging process. See also IEC 61709:2017, 4.6.
Each user can easily calculate failure rates at any condition using IEC 61709.

1   Scope
1.1   General
The aviation, space, and defence industries rely on the development and manufacture of complex products comprised of multiple systems, subsystems, and components each designed by individual designers (design activities) at various levels within the supply chain. Each design or manufacturing activity controls various aspects of the configuration and specifications related to the product. When a change to design or process is requested or required, the change is typically required to be evaluated against the impacts to the entire system.
Proposed changes to design data/information that the design activity identifies to be minor and have no effect on the product requirements or specifications, have the potential to be implemented and approved, where authorized to do so, but requires notification. Changes that affect customer mandated requirements or specifications shall be approved prior to implementation. In many cases, the design activity is not conducted by the DAH or design authority. The design activity may be several layers below the design approval. Irrespective of where the design activity is conducted in the supply chain, notification is required. The typical change notification flow is presented in Figure 1.
[Figure 1]
Submitting NOC data either electronically or conventionally on paper is subject to the terms and conditions of the customer’s contract. This also includes, where applicable, data access under the regulations of export control.
The process of exchanging, coordinating, and approving NOC data varies with the multiple relationships and agreements among all organizations concerned. An objective of this document is to provide the definition of a data set that can be integrated into any form of communication (e.g. electronic data interchange, submission of conventional paper forms). A sample form can be found in the Supply Chain Management Handbook (SCMH).
If all or part of this document is contractually invoked, design organizations and design holders (i.e. the organization responsible for the product end item design) that have responsibility for change management of products used on other higher-level designs shall use the information and processes defined in this document for submitting change notifications.
1.2   Application
This document defines the common NOC requirements for aviation, space, and defence organizations. The requirements that a design organization are to use when submitting a NOC to the customer for either change authorization or notification are included herein. A NOC informs the customer of physical or functional (e.g. design, material, software, maintenance) changes or any associated process changes to an established baseline configuration.
Retention of the NOC establishes a means of configuration control and captures the evolution of the part. This requirement is of utmost importance in commercial/civil aviation products where changes to type certificated products are mandated by regulations; however, these same concepts are also required in defence and space applications per contractual requirements.
Where there are changes to items which the organization does not have design input or is not permitted to make any changes to the design [e.g. build to print, Technical Standard Order (TSO) articles] then change requests are to be formally submitted to the customer and approved via the customer’s change request process.

This document defines a CCSDS Recommended Practice (and ISO standard) on which to base the operations of the organization(s) which assess the trustworthiness of digital repositories using the latest version of CCSDS 652.0/ISO 16363 (reference REF R_652x0m2AuditandCertificationofTrustwor \h[1] 08D0C9EA79F9BACE118C8200AA004BA90B02000000080000002900000052005F00360035003200780030006D0032004100750064006900740061006E006400430065007200740069006600690063006100740069006F006E006F0066005400720075007300740077006F0072000000 ) and provide the appropriate certification. This document specifies requirements for bodies providing audit and certification of digital repositories, based on the metrics contained within ISO/IEC 17021-1 (reference REF R_ISOIEC170212011ConformityAssessmentReq \h \* MERGEFORMAT [4] 08D0C9EA79F9BACE118C8200AA004BA90B02000000080000002900000052005F00490053004F0049004500430031003700300032003100320030003100310043006F006E0066006F0072006D006900740079004100730073006500730073006D0065006E0074005200650071000000 ) and reference REF R_652x0m2AuditandCertificationofTrustwor \h[1] 08D0C9EA79F9BACE118C8200AA004BA90B02000000080000002900000052005F00360035003200780030006D0032004100750064006900740061006E006400430065007200740069006600690063006100740069006F006E006F0066005400720075007300740077006F0072000000 . It is primarily intended to support the accreditation of bodies providing such certification. ISO/IEC 17021-1 provides the bulk of the requirements on bodies offering audit and certification for general types of management systems. However, for each specific type of system, specific additional requirements will be needed, for example, to specify the standard against which the audit is to be made and the qualifications which auditors require. This document provides the (small number of) specific additions required for bodies providing audit and certification of candidate trustworthy digital repositories. Trustworthy here means that they can be trusted to maintain, over the long-term, the understandability and usability of digitally encoded information placed into their safekeeping. In order improve readability the section numbers are kept consistent with those of ISO/IEC 17021-1. Some subsections are applicable as they stand, and these are simply enumerated; otherwise additions to subsections are explicitly given. In the former case the sections may consist of just a few sentences. As a result this document must be read in conjunction with ISO/IEC 17021-1. The requirements contained in this CCSDS Recommended Practice need to be demonstrated in terms of competence and reliability by any organization or body providing certification of digital repositories.

IEC 62309:2024 introduces the concept to check the reliability and functionality of reused parts and their usage within new products. It also provides information and criteria about the assurance [for example, testing and analysis, required for products containing reused parts, which are declared "qualified-as-good-as-new" (QAGAN)] relative to the designed life of the product.
This document specifies requirements to be satisfied before making a declaration or applying a designation of QAGAN. This document also gives guidance to support any organisation that makes declarations about dependability of products containing reused parts.
In this document, the term "product" covers electrical, electro-mechanical, mechanical parts or hardware that can contain software.
"Qualified-as-good-as-new" (QAGAN) does not apply to reused materials or large structures and large systems, nor does it cover software products, concepts, and ideas.
The purpose of this document is to ensure by tests and analysis that the reliability and functionality of a new product containing reused parts is comparable to a product that contains only new parts. This would justify the manufacturer granting the next customer the full warranty of the product with "qualified-as-good-as-new" (QAGAN) parts.
Annex A describes extending useful life by refurbishment, updating, upgrading, maintenance and used as second-hand. These concepts are defined and the requirements for using the term with reference to this document are stated.
This second edition cancels and replaces the first edition published in 2004. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) the previous Annex A has been separated into Annex B (Dependability aspects) and Annex C (Example with QAGAN parts);
b) a new normative Annex A has been written with expansion of lifecycle activities, to describe extending the useful life by refurbishment, life extension, updating, upgrading and second-hand use;
c) revision of Figure 1 accordingly;
d) minor editorial alignments throughout the document;
e) the abbreviation "quagan" has been changed "QAGAN" to reflect more contemporary use.

This part 1 of EN 50126
-   considers RAMS, understood as reliability, availability, maintainability and safety and their interaction;
-   considers the generic aspects of the RAMS life cycle. The guidance in this part can still be used in the application of specific standards;
-   defines:
-   a process, based on the system life cycle and tasks within it, for managing RAMS;
-   a systematic process, tailorable to the type and size of the system under consideration, for specifying requirements for RAMS and demonstrating that these requirements are achieved;
-   addresses railway specifics;
-   enables conflicts between RAMS elements to be controlled and managed effectively;
-   does not define:
-   RAMS targets, quantities, requirements or solutions for specific railway applications;
-   rules or processes pertaining to the certification of railway products against the requirements of this standard;
-   an approval process for the railway stakeholders.
This part 1 of EN 50126 is applicable to railway application fields, namely Command, Control and Signalling, Rolling Stock and Fixed Installations, and specifically:
-   to the specification and demonstration of RAMS for all railway applications and at all levels of such an application, as appropriate, from complete railway systems to major systems and to individual and combined subsystems and components within these major systems, including those containing software; in particular:
-   to new systems;
-   to new systems integrated into existing systems already accepted, but only to the extent and insofar as the new system with the new functionality is being integrated. It is otherwise not applicable to any unmodified aspects of the existing system;
-   as far as reasonably practicable, to modifications and extensions of existing systems already accepted, but only to the extent and insofar as existing systems are being modified. It is otherwise not applicable to any unmodified aspect of the existing system;
-   at all relevant phases of the life cycle of an application;
-   for use by railway duty holders and the railway suppliers.
It is not required to apply this standard to existing systems which remain unmodified, including those systems already compliant with any former version of EN 50126.
The process defined by this European Standard assumes that railway duty holders and railway suppliers have business-level policies addressing Quality, Performance and Safety. The approach defined in this standard is consistent with the application of quality management requirements contained within EN ISO 9001.
