IEC60300-1:2014 establishes a framework for dependability management. It provides guidance on dependability management of products, systems, processes or services involving hardware, software and human aspects or any integrated combinations of these elements. It presents guidance on planning and implementation of dependability activities and technical processes throughout the life cycle taking into account other requirements such as those relating to safety and the environment. This standard gives guidelines for management and their technical personnel to assist them to optimize dependability

Gives a general overview of commonly used dependability analysis techniques. It describes the usual methodologies, their advantages and disadvantages, data input and other conditions for using various techniques. It is an introduction to selected methodologies and is intended to provide the necessary information for choosing the most appropriate analysis methods.

The application guide can be used to implement a maintainability programme covering the initiation, development and in-service phases of a product, which form part of the tasks in IEC 60300-2. It provides guidance on how the maintenance aspects of the tasks should be considered in order to achieve optimum maintainability. It uses other IEC standards, notably IEC 60706, as reference documents or tools as to how a task should be undertaken. This standard replaces Sections 1 and 3 of IEC 60706-1:1982.

Describes a framework for maintenance and maintenance support and the various minimal common practices that should be undertaken. Outlines in a generic manner, management, processes and techniques related to maintenance and maintenance support that are necessary to achieve adequate dependability to meet the operational needs of the customer. Applicable to items, which include all types of products, equipment and systems (hardware and associated software). Most of these require a certain level of maintenance to ensure that their required functionality, dependability, capability, economic, safety and regulatory requirements are achieved.

IEC 62550:2017 describes requirements for spare parts provisioning as a part of supportability activities that affect dependability performance so that continuity of operation of products, equipment and systems for their intended application can be sustained. This document is intended for use by a wide range of suppliers, maintenance support organizations and users and can be applied to all items.

Applicable to any project with a technological content. Provides a general introduction to project risk management, its subprocesses and influencing factors. Guidelines are provided on the organizational requirements for implementing the process of risk management appropriate to the various phases of a project

Provides guidance in relation to a set of requirements placed upon system life cycles in order for an open system to achieve open systems dependability. This document elaborates on IEC 60300-1 by providing details of the changes needed to accommodate the characteristics of open systems. It defines process views based on ISO/IEC/IEEE 15288:2015, which identifies the set of system life cycle processes. This document is applicable to life cycles of products, systems, processes or services involving hardware, software and human aspects or any integrated combinations of these elements. For open systems, security is especially important since the systems are particularly exposed to attack. This document can be used to improve the dependability of open systems and to provide assurance that the process views specific to open systems achieve their expected outcomes. It helps an organization define the activities and tasks that need to be undertaken to achieve dependability objectives in an open system, including dependability related communication, dependability assessment and evaluation of dependability throughout system life cycles.

This technical specification, shows how the IEC dependability suite of standards, systems engineering and the IFRS and IAS standards can support the requirements of asset management, as described by the ISO 5500x suite of standards. It provides:

(a) a brief introduction to asset management and the requirements for an AMS,

(b) a description of the benefits from the use of an established and common set of AMS processes and procedures, tools and techniques to manage assets, and

(c) a description of the relationships between the AMS and the tools and techniques, processes and procedures of:

(i) ISO/IEC/IEEE 15288:2015, Systems and software engineering,

(ii) System lifecycle processes,

(iii) IEC dependability standards in particular IEC 60300-3-15, and

(iv) relevant IFRS and supporting IAS standards.

This technical specification is intended for:

(a) asset managers who wish to identify and implement technical and financial processes within an AMS, using dependability techniques and IFRS and IAS standards respectively, and

(b) systems and dependability engineers who need to apply their technical processes and techniques within an AMS.

IEC 60812:2018 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 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. This third edition cancels and replaces the second edition published in 2006. This edition constitutes a technical revision.This edition includes the following significant technical changes with respect to the previous edition:

a) the normative text is generic and covers all applications;

b) examples of applications for safety, automotive, software and (service) processes have been added as informative annexes;

c) tailoring the FMEA for different applications is described;

d) different reporting formats are described, including a database information system;

e) alternative means of calculating risk priority numbers (RPN) have been added;

f) a criticality matrix based method has been added;

g) the relationship to other dependability analysis methods have been described.

Describes fault tree analysis and provides guidance on its application to perform an analysis, identifies appropriate assumptions, events and failure modes, and provides identification rules and symbols.

This international standard provides guidance on the application of Markov techniques to model and analyze a system and estimate reliability, availability, maintainability and safety measures. This standard is applicable to all industries where systems, which exhibit state-dependent behaviour, have to be analyzed. The Markov techniques covered by this standard assume constant time-independent state transition rates. Such techniques are often called homogeneous Markov techniques.

Specifies the consolidated basic principles of event tree analysis (ETA) and provides guidance on modelling the consequences of an initiating event as well as analysing these consequences qualitatively and quantitatively in the context of dependability and risk related measures

Provides guidance on a Petri net based methodology for dependability purposes. It supports modelling a system, analysing the model and presenting the analysis results. This methodology is oriented to dependability-related measures with all the related features, such as reliability, availability, production availability, maintainability and safety (e.g. safety integrity level (SIL) [2] related measures).

Key words: Petri net based methodology for dependability purposes

Provides guidance on probabilistic risk analysis (hereafter referred to as risk analysis) for the systems composed of electrotechnical items and is applicable (but not limited) to all electrotechnical industries where risk analyses are performed. This document deals with the following topics from the perspective of risk analysis: defining the essential terms and concepts; specifying the types of events; classifying the occurrences of events; describing the usage of modified symbols and methods of graphical representation for ETA, FTA and Markov techniques for applying those modified techniques complementarily to the complex systems; suggesting ways to handle the event frequency/rate of complex systems; suggesting ways to estimate the event frequency/rate based on risk monitoring; providing illustrative and practical examples.

This part of IEC 60300 provides guidelines for the collection of data relating to reliability, maintainability, availability and maintenance support performance of items operating in the field. It deals in general terms with the practical aspects of data collection and presentation and briefly explores the related topics of data analysis and presentation of results. Emphasis is made on the need to incorporate the return of experience from the field in the dependability process as a main activity.

Describes the information needed for characterizing reliability of a component, and also the detailed requirements for reporting reliability data. Gives guidance to component users as to how they should specify their reliability requirements to component manufacturers. The data, derived from laboratory tests, should enable circuit and equipment designers to evaluate the reliability of circuits and systems.
