Petroleum products - Determination of cloud point - Automated step-wise cooling method (ISO 22995:2019)
This method determines cloud point using a step-wise cooling technique that is executed through automated equipment types with optical detection mode. This method is an alternative to the normal, manual technique as described in EN 23015. It is a generic method that covers existing automated equipment.
The determination method covers distillate fuels (automotive and marine), paraffinic diesel fuel, fatty acid methyl ester and blends thereof at 7% up to 30% in volume.
Mineralölerzeugnisse - Bestimmung des Cloudpoints - Verfahren mit automatischer schrittweiser Abkühlung (ISO 22995:2019)
Dieses Dokument legt ein Verfahren zur Bestimmung des Cloudpoints unter Anwendung eines stufenweisen Abkühlverfahrens fest, die Messung erfolgt dabei durch automatisch arbeitende Geräte mit optischer Detektion.
Das Verfahren gilt für Destillatkraftstoffe, Fettsäure-Methylester (FAME) und paraffinische Dieselkraftstoffe sowie Mischungen aus diesen, ebenso für solche, die Fließverbesserer oder sonstige Additive enthalten, die für die Verwendung in Dieselmotoren und Haushalts-Heizanlagen vorgesehen sind.
Das Verfahren kann auf weitere Produkte, wie z. B. pflanzliche Öle oder Schmierstoffe, angewendet werden, jedoch wurde diese Art von Produkten nicht in dem Ringversuch (en: interlaboratory study, ILS) beurteilt und somit stehen keine Präzisionsdaten zur Verfügung.
Produits pétroliers - Détermination du point de trouble - Méthode automatique par refroidissement par paliers (ISO 22995:2019)
Le présent document spécifie une méthode d'essai qui permet de déterminer, selon un mode de détection optique, le point de trouble de produits qui sont refroidis par paliers successifs au moyen d'un équipement automatisé.
La présente méthode est applicable aux combustibles distillés, aux esters méthyliques d'acides gras (EMAG) et aux carburants diesel paraffiniques, y compris leurs mélanges, ainsi qu'aux combustibles contenant des additifs comme ceux améliorant la fluidité, destinés à être utilisés dans des moteurs diesel et des installations de chauffage domestique.
Cette méthode peut être appliquée à d'autres produits tels que les huiles végétales ou lubrifiants mais ils n'ont pas été évalués lors de l'étude interlaboratoires.
Naftni proizvodi - Ugotavljanje točke zmotnitve - Metoda z avtomatskim stopenjskim ohlajanjem (ISO 22995:2019)
Ta metoda določa točko zmotnitve s tehniko stopenjskega ohlajanja, ki se izvaja prek avtomatiziranih vrst opreme z optičnim načinom zaznavanja. Ta metoda je alternativa običajni ročni tehniki, opisani v standardu EN 23015. Gre za generično metodo, ki zajema obstoječo avtomatizirano opremo.
Metoda določanja zajema destilatna goriva (avtomobilska in pomorska), parafinsko dizelsko gorivo, metil estre maščobnih kislin in njihove mešanice z vsebnostjo od 7 do 30 % vol.

Introduction
This document describes an automatic method for the determination of the cloud point, inspired by
[1]
the manual determination technique described in ISO 3015 . In comparison with that standard, the
scope of the present document has been modified for taking into account FAME, current available
distillate fuels as well as paraffinic diesel fuels, including those containing FAME, flow-improvers or
other additives, intended for use in diesel engines and domestic heating installation
