Coating powders - Part 11: Inclined-plane flow test (ISO 8130-11:2019)
This document specifies a comparative method for determining the flow characteristic of a fused thermosetting coating powder down a plane inclined at a set angle to the horizontal.
The aim of the test method described in this document gives an indication of the degree of melt flow that can occur during the curing of the coating powder. This characteristic contributes to the surface appearance and to the degree of coverage over sharp edges.
The test is a comparative method for checking for batch to batch variation in the behaviour of a given coating powder. Correlation between the results from coating powders of differing composition is not to be expected.
This method is not suitable for coating powders which have gel times of less than 1 min at the test temperature when characterised according to ISO 8130‑6. This method is also not suitable for textured powders.
Pulverlacke - Teil 11: Prüfung des Fließverhaltens auf einer geneigten Platte (ISO 8130-11:2019)
Dieses Dokument legt ein vergleichendes Verfahren zum Bestimmen der Fließeigenschaften eines geschmolzenen wärmehärtenden Pulverlackes entlang einer Ebene, die in einem festgelegten Winkel zur Waagerechten geneigt ist, fest.
Das Ergebnis des in diesem Dokument beschriebenen Prüfverfahrens gibt einen Hinweis auf den Grad des Schmelzflusses, der beim Härten von Pulverlacken auftreten kann. Diese Kenngröße wirkt sich auf das Aussehen der Oberfläche und den Grad der Abdeckung über scharfen Kanten aus.
Die Prüfung ist ein vergleichendes Verfahren und dient zur Kontrolle des Verhaltens eines bestimmten Pulverlackes auf Unterschiede von Charge zu Charge. Bei Pulverlacken mit unterschiedlicher Zusammensetzung ist eine Korrelation der Ergebnisse nicht zu erwarten.
Das Verfahren ist nicht bei Pulverlacken, die nach ISO 8130 6 kürzere Gelzeiten als 1 min bei der Prüftemperatur aufweisen, anwendbar. Das Verfahren ist ebenfalls nicht auf Strukturpulver anwendbar.
Poudres pour revêtement - Partie 11: Essai d'écoulement sur plan incliné (ISO 8130-11:2019)
Le présent document spécifie une méthode comparative visant à déterminer les caractéristiques d'écoulement d'une poudre pour revêtement thermodurcissable en fusion le long d'un plan incliné, selon un angle donné par rapport à l'horizontale.
L'objectif de la méthode d'essai décrite dans le présent document est de fournir une indication du degré de fluidité pouvant se présenter au cours du durcissement de la poudre pour revêtement. Cette caractéristique concourt à l'aspect de surface et au degré de recouvrement des arêtes vives.
Cet essai est une méthode comparative permettant de contrôler les variations d'un lot à l'autre dans le comportement d'une poudre pour revêtement donnée. Il ne faut pas s'attendre à observer une corrélation entre les résultats de poudres pour revêtement de différentes compositions.
La présente méthode n'est pas adaptée aux poudres pour revêtement présentant des temps de gélification inférieurs à 1 min à la température d'essai, lorsqu'ils sont déterminés conformément à l'ISO 8130‑6. La présente méthode n'est pas non plus adaptée aux poudres texturées.
Praškasti premazi - 11. del: Preskus tečenja na nagnjeni površini (ISO 8130-11:2019)
Ta dokument določa primerjalno metodo za določanje značilnosti pretoka spojenega termoreaktivnega praškastega premaza navzdol po ravnini, nagnjeni pod določenim kotom glede na vodoravno površino.
Cilj preskusne metode, ki je opisan v tem dokumentu, navaja stopnjo pretoka taline, ki lahko nastane med sušenjem praškastega premaza. Te značilnosti prispevajo k videzu površine in stopnji prekritosti ostrih robov.
Preskus je primerjalna metoda za preverjanje razlik med posameznimi serijami v vedenju danega praškastega premaza. Korelacija med rezultati praškastih premazov z različno sestavo ni pričakovana.
Ta metoda ni primerna za praškaste premaze s časom želiranja pod 1 min pri preskusni temperaturi, če so določeni v skladu s standardom ISO 8130-6. Ta metoda prav tako ni primerna za teksturirane praške.

Overview
SIST EN ISO 8130-11:2019 is a European and International Standard developed by CEN and ISO Technical Committees for testing coating powders. It specifies a comparative method to determine the flow characteristics of fused thermosetting coating powders as they move down an inclined plane at a set angle. This test provides an indication of the degree of melt flow during curing of the powder coating, which plays a crucial role in the surface appearance and coverage over sharp edges of coated materials.
This standard is essential for quality control, enabling manufacturers to monitor batch-to-batch variation in powder flow behavior. It is not applicable for powders with gel times under 1 minute at test temperature or for textured powders.
Key Topics
Scope and Purpose
- Measures melt flow of thermosetting coating powders on an inclined heated plane
- Helps assess surface finish quality and edge coverage during curing
- Comparative method intended to identify batch variations
Test Principle
- A pellet of the coating powder is formed and pressed into a standard size
- Pellet is heated on an inclined plate, and the flow distance over a fixed time is measured
Test Conditions
- Inclination angle fixed at (65 ± 1)° to horizontal
- Temperature typically (180 ± 2) °C or recommended curing temperature
- Duration: pellet flows for 15 minutes before measuring flow length
Apparatus Requirements
- Fan-assisted air circulation oven capable up to 250 °C
- Rigid glass or metal plates with defined thickness and surface finish
- Pellet mounding press to form test samples (12.5 mm diameter, 6.5 mm thick)
- Precision balance, graduated ruler, and plate assembly for heating
Testing Procedure
- Weigh approximately 0.5–0.75 g of powder
- Compress to form pellet, place on preheated plate in oven
- Flow test performed with oven door briefly opened twice for positioning
- Measure melt flow length after cooling to determine flow characteristics
Applicability Limitations
- Not suitable for powders with gel time less than 1 minute (ISO 8130-6)
- Not applicable for textured coating powders
- Results are comparative and valid only when testing the same powder under consistent conditions
Applications
SIST EN ISO 8130-11:2019 serves coating powder manufacturers, quality assurance labs, and coatings formulators that need reliable, repeatable flow characteristic data for fused thermosetting powders. Applications include:
- Quality control of coating powders to ensure consistent melt flow properties batch-to-batch
- Product development and testing for new powder coating formulations
- Surface finish evaluation related to flow behavior influencing coverage of edges and uniformity
- Comparative testing to monitor and optimize cure parameters in production environments
- Regulatory and compliance documentation referencing ISO standards for coating powders
This method helps prevent defects related to insufficient or excessive flow during curing, such as poor edge coverage, runs, or texture anomalies, making it valuable in automotive, industrial, and architectural powder coating industries.
Related Standards
To complement SIST EN ISO 8130-11:2019, relevant standards include:
- ISO 8130-6: Determination of gel time of thermosetting coating powders - important to ensure test suitability
- ISO 8130-2 and ISO 8130-3: Methods for determining coating powder density by gas comparison and liquid displacement pyknometers, respectively
- ISO 8130-14: Vocabulary related to coating powders for consistent terminology
- ISO 15528: Guidelines for sampling paints, varnishes, and raw materials essential for preparing proper test samples
By following these harmonized standards, laboratories can ensure accuracy, repeatability, and international comparability in their coating powder testing protocols.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
