1.1 This International Standard covers those aspects to be considered when electrical/electronic/programmable electronic (E/E/PE) systems are used to carry out safety functions. A major objective of this standard is to facilitate the development of product and application sector international standards by the technical committees responsible for the product or application sector. This will allow…

1.1 This part of the IEC 61508 series a) is intended to be utilized only after a thorough understanding of IEC 61508-1 and IEC 61508-2; b) applies to any software forming part of a safety-related system or used to develop a safety-related system within the scope of IEC 61508-1 and IEC 61508-2. Such software is termed safety-related software (including operating systems, system software, software…

This part of IEC 61511 gives requirements for the specification, design, installation, operation and maintenance of a safety instrumented system (SIS), so that it can be confidently entrusted to achieve or maintain a safe state of the process. IEC 61511-1 has been developed as a process sector implementation of IEC 61508:2010. In particular, IEC 61511-1: a) specifies the requirements for…

1.1 Facilities and workplaces impacted This Standard identifies the requirements for a PSM system for facilities and worksites handling or storing materials that are potentially hazardous, either due to an inherent chemical, biological, toxicological, or physical property of those materials, or due to the material’s potential or kinetic energy 1.2 Minimum lifecycle requirements This Standard…

ISO 18400-100:2017 describes the structure of sampling standards for any kind of soil investigation. It also describes the coherence of the different parts in the ISO 18400 series. It provides guidance on the selection of sampling standards appropriate for the objectives of users.

IEC TR 62453-62:2017(E), which is a Technical Report, explains the guidelines and rules for the CLI‑based implementation of a Device Type Manager (DTM) and parts of a Frame Application with regard to the user interface and its behaviour. These guidelines and rules are part of the FDT specification (IEC TR 62453‑42) and are intended to ensure that all users are provided with clear and consistent…

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.

IEC TR 61869-100:2017(E) is applicable to inductive protective current transformers meeting the requirements of the IEC 61869-2 standard. It may help relay manufacturers, CT manufacturers and project engineers to understand how a CT responds to simplified or standardized short circuit signals. Therefore, it supplies advanced information to comprehend the definition of inductive current…

ISO/IEC 19752:2017 is limited to the evaluation of toner cartridge page yield for toner containing cartridges (i.e. all-in-one toner cartridges and toner cartridges without a photoconductor) for monochrome electrophotographic print systems. This document could also be applied to the printer component of any multifunctional device that has a digital input-printing path (i.e. multi-function devices…

The scope of ISO/IEC 19798:2017 is limited to evaluation of toner cartridge page yield for toner-containing cartridges (i.e. all-in-one toner cartridges and toner cartridges without a photoconductor) for colour electrophotographic print systems. This document can also be applied to the printer component of any multifunctional device that has a digital input printing path, including multi-function…
