IEC 60911:2025 applies to pressurized water reactors (PWRs) and presents requirements for the monitoring of adequate cooling within the core in all operations, including normal and abnormal operations. Requirements for core cooling monitoring during conditions beyond a design basis accident, i.e. a design extension condition of type A or type B, are also covered in this document. This document…

Le présent document décrit les principes généraux et les techniques pour la caractérisation et le dimensionnement des discontinuités détectées au préalable afin de les évaluer correctement par rapport aux critères d’acceptation applicables. Le présent document s’applique, en termes génériques, aux discontinuités des matériaux et applications couvertes par l’ISO 16810. Des techniques de contrôle…

This document specifies the minimum values for expected strength as a function of time and temperature in the form of reference lines, for use in calculations on pipes made of a)       polyethylene of raised temperature resistance (PE-RT) type I, and b)       polyethylene of raised temperature resistance (PE-RT) type II.

This document specifies technical exchange formats for audit data collection, customs and indirect tax extension, in Extensible Markup Language (XML), JavaScript Object Notation (JSON) and flat file (CSV) as output file formats for the functional content defined in ISO 5401. This document also contains the following schema files and mapping tables related to ISO 5401: —     XML schema files…

This document specifies the characteristics of prevailing torque hexagon high nuts (with non‑metallic insert), in steel and stainless steel, with metric coarse pitch thread M5 to M39, and with product grades A and B. NOTE            These nuts are designed with an overall height equal to mmin (as specified in ISO 898-2 and ISO 4033 for style 2) plus the prevailing torque feature. The height of…

Le présent document spécifie les caractéristiques des écrous hauts hexagonaux autofreinés (à anneau non métallique), en acier et en acier inoxydable, à filetage métrique à pas gros M5 à M39, et de grades A et B. NOTE            Ces écrous sont conçus avec une hauteur totale égale à mmin (tel que spécifié dans l’ISO 898-2 et l’ISO 4033 pour le style 2) plus le dispositif d’autofreinage. La hauteur…

This document specifies the general principles and techniques for the characterization and sizing of previously detected discontinuities in order to ensure their evaluation against applicable acceptance criteria. This document is applicable, in general terms, to discontinuities in those materials and applications covered by ISO 16810. Phased array techniques can also be applied but additional…

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…

IEC 61097-7:2025 specifies the minimum performance requirements, technical characteristics and test methods with required test results for VHF radio installations capable of voice communication and digital selective calling as required by chapter IV of the International Convention for Safety of Life at Sea (SOLAS). This document incorporates the applicable part of the performance standards…
