Power systems management and associated information exchange - Interoperability in the long term - P...
IEC TR 62361-103:2018(E), which is a technical report, describes the concepts of standard profiling for Common Information Model (CIM – IEC 61970, IEC 61968, IEC 62325) and IEC 61850 standard series. It serves as an introduction to profiling concepts and methodologies for the development of profiles for providing interoperability. It describes the specific needs and requirements of the standard…
Nuclear power plants - Instrumentation, control and electrical power systems important to safety - S...
IEC 60709:2018 is applicable to nuclear power plant instrumentation and control (I&C) and electrical systems and equipment, whose functions are required to be independent due to their contribution to:
a redundant or diverse safety group;
different defence in depth levels;
different safety classes and also with non-classified (NC) systems.
This standard is also applicable to…
Centrales nucléaires de puissance - Systèmes d'instrumentation, de contrôle-commande et d'...
L'IEC 60709:2018 est applicable aux systèmes d’instrumentation et de contrôle-commande (I&C) des centrales nucléaires de puissance ainsi qu’aux systèmes et équipements électriques, dont il est exigé que les fonctions soient indépendantes en raison de leur contribution à:
un groupe de sûreté redondant ou varié;
différents niveaux de défense en profondeur;
différentes classes de…
Surface chemical analysis — Guidelines to sample handling, preparation and mounting — Part 4: Report...
ISO 20579-4:2018 identifies information to be reported in a datasheet, certificate of analysis, report or other publication regarding the handling of nano-objects in preparation for surface chemical analysis. This information is needed to ensure reliability and reproducibility of analyses needed to advance research and technology using these materials, and for obtaining appropriate understanding…
Hydraulic fluid power — Hose and hose assemblies — Method of collecting a fluid sample for analyzing...
ISO/TS 18409:2018 specifies two methods for collecting a fluid sample to be used to analyse the cleanliness of hydraulic fluid power hoses or hose assemblies within a certain inside diameter and length range (this range includes the majority of hose assemblies of real fluid power applications).
The two methods described in this document are intended for collecting only solid particulate…
Thermoplastics piping systems for underground non-pressure applications — Test method for leaktightn...
This document specifies a test method for determining the leak tightness of elastomeric sealing ring type joints for buried thermoplastics non-pressure piping systems.
Unless otherwise specified in the referring standard, the tests are carried out at the following basic test pressures:
— p1: internal negative air pressure (partial vacuum);
— p2: a low internal hydrostatic…
Plastiques — Méthodes d'exposition au rayonnement solaire — Partie 3: Exposition intensifiée pa...
ISO 877-3:2018 spécifie une méthode d'exposition des plastiques à un rayonnement solaire concentré à l'aide de concentrateurs réfléchissants pour accélérer le processus d'exposition aux intempéries. L'objectif consiste à évaluer les changements produits après des phases d'exposition spécifiées. Les concentrateurs réfléchissants utilisés dans ces essais d'exposition…
Qualité du sol — Disponibilité environnementale des composés organiques non polaires — Détermination...
ISO/TS 16751:2018 spécifie une méthode d'extraction pour déterminer la fraction biodisponible (disponibilité potentielle et environnementale) et la fraction non biodisponible d'un contaminant dans le sol en utilisant une «phase réceptrice» pour un contaminant organique, phase à fortes propriétés sorbantes ou à propriétés complexantes, par exemple, le Tenax®[1] ou la cyclodextrine,…
Petroleum and related products — Determination of spray ignition characteristics of fire-resistant f...
ISO 15029-2:2018 specifies a method by which the fire hazards of pressurised sprays of fire-resistant fluids can be compared. Two sizes of propane flame are used to ignite and stabilise combustion of an air-atomised release of fluid. Measurements related to the rate of heat release, length of flame and density of smoke give quantitative information on the fire behaviour of the fluid.
