Annotation of standard text IEC 60534-2-3-ed.3.0 :
IEC 60534-2-3:2015 is applicable to industrial-process control valves and provides the flow capacity test procedures for determining the following variables used in the equations given in IEC 60534-2-1: a) flow coefficient C; b) liquid pressure recovery factor without attached fittings FL; c) combined liquid pressure recovery factor and piping geometry factor of a control valve with attached fittings FLP; d) piping geometry factor FP; e) pressure differential ratio factors xT and xTP; f) valve style modifier Fd; g) Reynolds number factor FR. This third edition cancels and replaces the second edition published in 1997, of which it constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) Addition of informative Annexes B, C, D, E and F. b) Organizational and formatting changes were made to group technically related subject matter. L’IEC 60534-2-3:2015 est applicable aux vannes de regulation des processus industriels. Elle donne les procedures dessai relatives a la capacite decoulement pour la determination des variables enoncees ci-apres, utilisees dans les equations de l’IEC 60534-2-1: a) coefficient de debit C; b) facteur de recuperation de pression du liquide sans raccords adjacents FL; c) facteur combine de recuperation de pression du liquide et de geometrie de la tuyauterie d’une vanne de regulation avec raccords adjacents FLP; d) facteur resultant de la geometrie de la tuyauterie FP; e) facteurs de rapport de pression differentielle xT et xTP; f) coefficient de correction generique de vanne Fd; g) facteur du nombre de Reynolds FR.
