IEC 60793-1-44: 2023 établit des exigences uniformes pour mesurer la longueur d’onde de coupure des fibres optiques unimodales, contribuant ainsi au contrôle des fibres et câbles dans des relations commerciales. Le présent document donne des méthodes de mesure de la longueur d’onde de coupure pour les fibres de télécommunications unimodales câblées ou non câblées. Ces procédures s’appliquent à…

This document applies to electric and electronic systems and components for vehicles including electric propulsion systems and components with maximum working voltages according to voltage class B. It describes the potential environmental stresses and specifies tests and requirements recommended for the specific mounting location on/in the vehicle. This document describes climatic loads. This…

This document specifies the standards for design and construction using the top-surface overlaying method, which increases the thickness of existing concrete members by integrating cementitious materials onto the top surface of the members so as to improve the safety, serviceability, durability and other properties of a concrete structure. This document specifies structural intervention of…

This document specifies the standards for design and construction using the bottom-surface (soffit) underlaying method. Bottom-surface (soffit) underlaying is a method whereby reinforcing materials are placed on the bottom surface of the slabs or beams whose performance is lower than required and the improvement of durability, serviceability, safety and other performance of the members is…

This document specifies the standards for design, construction and maintenance following completion of intervention to be applied for performing intervention work using cementitious materials to improve the performance of existing concrete structures. The intervention dealt with in this document is intended to restore, sustain or improve the mechanical performance of concrete structures. When the…

This document specifies two test methods (method A and method B) for determining the longitudinal tensile properties of glass-reinforced thermosetting plastics (GRP) pipes. The properties which can be determined are: —     the longitudinal tensile strength, and —     the percentage ultimate elongation. Method A uses, for the test piece(s), a longitudinal strip cut from a pipe. Method B uses a…

This document specifies definitions, terminology and processes for secure multiparty computation and related technology, in order to establish a taxonomy and enable interoperability. In particular, this document defines the processes involved in cryptographic mechanisms which compute a function on data while the data are kept private; the participating parties; and the cryptographic properties.…

This document specifies the standard requirements regarding design, construction and maintenance to be applied for structural intervention using the jacketing method, which places reinforcing materials such as reinforcing steel or fibre-reinforced polymer (FRP) grids around the periphery of existing concrete column or beam and jackets these members with cementitious materials. This document…

This document gives general guidance for the stages in the life cycle of a system’s biometric and associated elements. This covers the following: — the capture and design of initial requirements, including legal frameworks; — development and deployment; — operations, including enrolment and subsequent usage; — interrelationships with other systems; — related data storage and…
