Ed 1 In Progress
International Electrotechnical Vocabulary - Part 692: Electric power systems: dependability and quality of service
IEC 61703:2016 provides mathematical expressions for selected reliability, availability, maintainability and maintenance support measures defined in IEC 60050-192:2015. In addition, it introduces some terms not covered in IEC 60050-192:2015. They are related to aspects of the system of item classes (see hereafter). According to IEC 60050-192:2015, dependability [192-01-22] is the ability of an item to perform as and when required and an item [192-01-01] can be an individual part, component, device, functional unit, equipment, subsystem, or system. To account for mathematical constraints, this standard splits the items between the individual items considered as a whole (e.g. individual components) and the systems made of several individual items. It provides general considerations for the mathematical expressions for systems as well as individual items but the individual items which are easier to model are analysed in more detail with regards to their repair aspects. This standard is mainly applicable to hardware dependability, but many terms and their definitions may be applied to items containing software. This second edition cancels and replaces the first edition published in 2001. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - standard made as self containing as possible; - item split between individual items and systems; - generalization of the dependability concepts for systems made of several components [introduction of the conditional failure intensity (Vesely failure rate); - introduction of the state-transition and the Markovian models; - generalization of the availability to production availability]; - introduction of curves to illustrate the various concepts. Keywords: mathematical expressions for dependability

IEC 62198 (2013-11)
Project risk management  Application guidelines
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. Keywords: dependability of open systems
Provides guidance for an engineering system's dependability and describes a process for realization of system dependability through the system life cycle.

Introduces the concept to check the reliability and functionality of reused parts and their usage within new products. Also provides information and criteria about the tests/analysis required for products containing such reused parts, which are declared "qualified-as-good-as-new" relative to the designed life of the product. The purpose of this standard is to ensure by tests and analysis that the reliability and functionality of a new product containing reused parts is comparable to a product with only new parts.
Provides 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. Keywords: dependability, reliability, availability, maintainability, supportability, usability, testability, durability.

ISO 14224 (2016)
ISO 14224:2016 provides a comprehensive basis for the collection of reliability and maintenance (RM) data in a standard format for equipment in all facilities and operations within the petroleum, natural gas and petrochemical industries during the operational life cycle of equipment. It describes data collection principles and associated terms and definitions that constitute a "reliability language" that can be useful for communicating operational experience. The failure modes defined in the normative part of this International Standard can be used as a "reliability thesaurus" for various quantitative as well as qualitative applications. This International Standard also describes data quality control and assurance practices to provide guidance for the user. Standardization of data collection practices facilitates the exchange of information between parties, e.g. plants, owners, manufacturers and contractors. This International Standard establishes requirements that any in-house or commercially available RM data system is required to meet when designed for RM data exchange. Examples, guidelines and principles for the exchange and merging of such RM data are addressed. This International Standard also provides a framework and guidelines for establishing performance objectives and requirements for equipment reliability and availability performance. Annex A contains a summary of equipment that is covered by this International Standard. ISO 14224:2016 defines a minimum amount of data that is required to be collected, and it focuses on two main issues: - data requirements for the categories of data to be collected for use in various analysis methodologies; - standardized data format to facilitate the exchange of reliability and maintenance data between plants, owners, manufacturers and contractors. The following main categories of data are to be collected: a) equipment data, e.g. equipment taxonomy, equipment attributes; b) failure data, e.g. failure cause, failure consequence; c) maintenance data, e.g. maintenance action, resources used, maintenance consequence, down time. NOTE Clause 9 gives further details on data content and data format. The main areas where such data are used are the following: 1) reliability, e.g. failure events and failure mechanisms; 2) availability/efficiency, e.g. equipment availability, system availability, plant production availability; 3) maintenance, e.g. corrective and preventive maintenance, maintenance plan, maintenance supportability; 4) safety and environment, e.g. equipment failures with adverse consequences for safety and/or environment. ISO 14224:2016 does not apply to the following: i. data on (direct) cost issues; ii. data from laboratory testing and manufacturing (e.g. accelerated lifetime testing), see also 5.2; iii. complete equipment data sheets (only data seen relevant for assessing the reliability performance are included); iv. additional on-service data that an operator, on an individual basis, can consider useful for operation and maintenance; v. methods for analysing and applying RM data (however, principles for how to calculate some basic reliability and maintenance parameters are included in the annexes).

ISO 31000:2009 provides principles and generic guidelines on risk management.ISO 31000:2009 can be used by any public, private or community enterprise, association, group or individual. Therefore, ISO 31000:2009 is not specific to any industry or sector. ISO 31000:2009 can be applied throughout the life of an organization, and to a wide range of activities, including strategies and decisions, operations, processes, functions, projects, products, services and assets.ISO 31000:2009 can be applied to any type of risk, whatever its nature, whether having positive or negative consequences. Although ISO 31000:2009 provides generic guidelines, it is not intended to promote uniformity of risk management across organizations. The design and implementation of risk management plans and frameworks will need to take into account the varying needs of a specific organization, its particular objectives, context, structure, operations, processes, functions, projects, products, services, or assets and specific practices employed. It is intended that ISO 31000:2009 be utilized to harmonize risk management processes in existing and future standards. It provides a common approach in support of standards dealing with specific risks and/or sectors, and does not replace those standards. ISO 31000:2009 is not intended for the purpose of certification.
