Corrosion of metals and alloys - Corrosion and fouling in industrial cooling water systems - Part 2: Evaluation of the performance of cooling water treatment programmes using a pilot-scale test rig (ISO 16784-2:2024)
This document specifies the principles, reagents and materials, test apparatus, test methods, evaluation of results and requirements for test reports using pilot tests for industrial cooling water systems.
This document specifies a method to evaluate the performance of treatment programmes for open recirculating cooling water systems. It is based primarily on laboratory testing, but the heat exchanger testing facility can also be used for on-site evaluation. This document does not include heat exchangers with cooling water on the shell-side (i.e. external to the tubes).
Korrosion von Metallen und Legierungen - Korrosion und Fouling in industriellen Kühlwassersystemen - Teil 2: Bewertung der Leistung von Kühlwasser-Behandlungsprogrammen unter Anwendung eines Modell‑Prüfstands (ISO 16784‑2:2024)
Dieses Dokument legt die Grundsätze, Reagenzien und Hilfsstoffe, die Prüfeinrichtung, Prüfverfahren, die Auswertung der Ergebnisse und die Anforderungen an die Prüfberichte mithilfe von Versuchen für industrielle Kühlwassersysteme fest.
Dieses Dokument legt ein Verfahren zur Bewertung der Leistung von Behandlungsprogrammen für offene Kühlwasserrezirkulationssysteme fest. Das Verfahren basiert primär auf Laborprüfungen, der Prüfstand, der einen Wärmetauscher simuliert, kann aber auch für eine Bewertung vor Ort (am Standort der Anlage) verwendet werden. In diesem Dokument werden keine Wärmetauscher mit mantelseitigem Kühlwasser (d. h. Kühlwasser außerhalb der Rohre) erfasst.
Corrosion des métaux et alliages - Corrosion et encrassement des circuits de refroidissement à eau industriels - Partie 2: Évaluation des performances des programmes de traitement de l'eau de refroidissement sur banc d'essai pilote (ISO 16784-2:2024)
Le présent document spécifie les principes, les réactifs et matériaux, l’appareillage d’essai, les méthodes d’essai, les méthodes d’évaluation des résultats et les exigences relatives aux rapports d’essai dans le cadre des essais pilotes des circuits de refroidissement à eau industriels.
Le présent document spécifie une méthode d’évaluation des performances des programmes de traitement destinés aux circuits de refroidissement à eau à recirculation ouverts. Elle repose principalement sur des essais en laboratoire, mais l’installation d’essai d’échangeur de chaleur peut également servir à une évaluation sur site. Le présent document ne traite pas des échangeurs de chaleur dans lesquels l’eau de refroidissement se trouve côté calandre (c’est-à-dire externe aux tubes).
