Corrosion of metals and alloys - Corrosion and fouling in industrial cooling water systems - Part 1: Guidelines for conducting pilot-scale evaluation of corrosion and fouling control additives for open recirculating cooling water systems (ISO 16784-1:2024)

ISO 16784-1:2006 applies to corrosion and fouling in industrial cooling water systems.
ISO 16784-1:2006 covers the criteria that must be defined and implemented in a pilot-scale testing programme to select water treatment programmes for use in specific recirculating cooling water systems.
ISO 16784-1:2006 covers only open recirculating cooling water systems. Closed cooling systems and once-through cooling water systems are specifically excluded.
The test criteria established in ISO 16784-1:2006 are not intended to govern the type of bench and pilot-scale testing normally carried out by water treatment companies as part of their proprietary product-development programmes. However, water treatment companies may choose to use the criteria in ISO 16784-1:2006 as guidelines in the development of their own product-development test procedures.

Korrosion von Metallen und Legierungen - Korrosion und Fouling in industriellen Kühlwassersystemen - Teil 1: Leitfaden für die Bewertung von Zusatzstoffen gegen Korrosion und Fouling in offenen Kühlwasserrezirkulationssystemen (ISO 16784-1:2024)

Dieses Dokument legt allgemeine Anforderungen und Parameter für die Bewertung von Zusatzstoffen zur Kontrolle von Korrosion und Ablagerungen in offenen Kühlwasserkreisläufen im Modellversuch fest. Dieses Dokument deckt Parameter einschließlich der Auslegung der Prüfeinheit, des Betriebs, der Wasserqualität und der Verunreinigung ab. Es deckt auch die Auslegung und den Betrieb von Modell-Prüfeinheiten sowie die Parameter, die in Modelleinrichtungen zu bewerten sind, ab.
Dieses Dokument deckt die Kriterien ab, die bei einem Prüfprogramm für die Auswahl von Kühlwasser-Behandlungsprogrammen für bestimmte Kühlwasserrezirkulationssysteme angewendet werden müssen.
Dieses Dokument gilt nur für offene Kühlwasserrezirkulationssysteme. Es gilt nicht für geschlossene Kühlsysteme und Zwangsdurchlaufkühlsysteme.
Dieses Dokument gilt nur für Systeme, in denen Rohrbündelwärmetauscher mit genormten, unbeschichteten, glatten Rohren und rohrseitigem Kühlwasser angewendet werden. Dieses Dokument gilt nicht für Wärmetauscher mit mantelseitigem Wasser, Platten- und Rahmenwärmetauscher und/oder Spiralwärmetauscher und andere Wärmetauscher. Wenn jedoch die Prüfbedingungen so abgestimmt werden, dass Oberflächentemperatur und Scherspannung in komplexen Wärmeübertragungseinrichtungen nachzuvollziehen sind, kann aus den Prüfergebnissen vorhergesagt werden, wie sich ein in Betrieb befindlicher Wärmetauscher dieser Ausführung verhält.
Die in diesem Dokument zusammengestellten Prüfkriterien haben nicht den Zweck, die Art der Labor- und Modellprüfung vorzugeben, die üblicherweise von den Wasseraufbereitungsverbänden als Teil ihrer firmeneigenen Produktentwicklungsprogramme durchgeführt wird. Es steht den Wasseraufbereitungsverbänden frei, Kriterien aus diesem Dokument als Leitfaden zur Entwicklung eigener Prüfverfahren für die Produktentwicklung auszuwählen.

Corrosion des métaux et alliages - Corrosion et entartrage des circuits de refroidissement à eau industriels - Partie 1: Lignes directrices pour l'évaluation pilote des additifs anticorrosion et antitartre pour circuits de refroidissement à eau à recirculation ouverts (ISO 16784-1:2024)

L'ISO 16784-1:2006 s'applique à la corrosion et à l'entartrage des circuits de refroidissement industriels.
L'ISO 16784-1:2006 traite des critères à définir et à appliquer dans un programme d'essai pilote destiné à sélectionner des programmes de traitement de l'eau utilisés pour les circuits de refroidissement à recirculation.
L'ISO 16784-2006 ne concerne que les circuits de refroidissement à recirculation ouverts. Les circuits de refroidissement fermés et les circuits à eau de refroidissement non recyclée sont spécifiquement exclus.
Les critères d'essai établis dans l'ISO 16784-1:2006 n'ont pas pour objectif d'imposer le type particulier d'essai au banc et à l'échelle pilote habituellement effectué par les entreprises de traitement des eaux dans le cadre de leurs programmes de développement de produits brevetés. Les entreprises de traitement des eaux ont néanmoins la possibilité d'utiliser les critères de l'ISO 16784-1:2006 comme lignes directrices pour créer leurs propres méthodes d'essai pour le développement de produits.
