IEC 60193:2019 est applicable aux modèles de laboratoire de tout type de turbine hydraulique à action ou à réaction, de pompe d'accumulation ou de pompe-turbine. Il s'applique aux modèles de machines prototypes ayant une puissance unitaire supérieure à 5 MW ou un diamètre de référence supérieur à 3 m. Bien que l'application intégrale des procédures prescrites ne soit généralement…

IEC 61158-3-12:2019 defines the services provided to the Type 12 fieldbus application layer at the boundary between the application and data-link layers of the fieldbus reference model and systems management at the boundary between the data-link layer and systems management of the fieldbus reference model. This fourth edition cancels and replaces the third edition published in 2014. It…

IEC 61158-3-19:2019 defines the services provided to the Type 19 fieldbus application layer at the boundary between the application and data-link layers of the fieldbus reference model and systems management at the boundary between the data-link layer and systems management of the fieldbus reference model. This fourth edition cancels and replaces the third edition published in 2014. It…

IEC 61158-3-4:2019 defines the services provided to the Type 4 fieldbus application layer at the boundary between the application and data-link layers of the fieldbus reference model and systems management at the boundary between the data-link layer and systems management of the fieldbus reference model. This third edition cancels and replaces the second edition published in 2014. It constitutes…

IEC 61158-3-21:2019 defines in an abstract way the externally visible service provided by the Type 21 fieldbus data-link layer in terms of the primitive actions and events of the service; the parameters associated with each primitive action and event, and the form which they take and the interrelationship between these actions and events, and their valid sequences. It cancels and replaces the…

This document describes the processes of an Offering Party's implementation to provide (ISO 20078‑2) Access controlled (ISO 20078-3) Resources (ISO 20078‑1) to Accessing Parties. The processes are summarized as: Registration of different stakeholder as well as granting, denying and revoking of Access to Resources. Those processes are held as examples of combining ISO 20078‑1, ISO 20078‑2 and…

This document provides guidelines for the identification of distributions related to the implementation of Six Sigma. Examples are given to illustrate the related graphical and numerical procedures. It only considers one dimensional distribution with one mode. The underlying distribution is either continuous or discrete.

This document specifies the requirements for the profiles, dimensions, tolerances, materials and inspection of chain wheels for chains on mobile offshore units. Chain wheels meeting the requirements of this document can be used with offshore mooring chains conforming to ISO 20438.

This document specifies tolerances on form and position as well as the surface roughness of shafts, flanges and thrust collars as used in plain bearing units. It is applicable to journal or thrust plain bearing units or to a combination of both, installed either horizontally or vertically. This document is not applicable to crankshaft bearing units in combustion engines.

Le présent document spécifie des lignes directrices concernant les aspects techniques, les outils et les bonnes pratiques en matière de gestion d'actifs des stations d'épuration des eaux usées, installations de traitement des boues, stations de pompage et installations de rétention et de retenue, afin de préserver la valeur des actifs existants.
