Pigments and extenders - Methods of dispersion and assessment of dispersibility in plastics - Part 5: Determination by filter pressure value test
This part of EN 13900 specifies a method of assessing the degree of dispersion of a colorant in a thermoplastic polymer.
The method is suitable for testing colorants in the form of colour concentrates in all polymer used for extrusion and melt-spinning processes.
The filter pressure value (FPV) determined according to this method is valid only for the equipment, conditions and test polymer being used. The use of test conditions differing from those specified may give different results. The method of preparing the colour concentrate is not specified in this standard. The results obtained for individual colorants are therefore comparable only when the same method of preparation for colour concentrates is used.
Annex A is normative and gives a model for the breaker plate.
Annex B is informative and provides a model test report containing a result of the round robin tests carried out in preparing this standard.
Pigmente und Füllstoffe - Dispergierverfahren und Beurteilung der Dispergierbarkeit in Kunststoffen - Teil 5: Bestimmung mit dem Druckfiltertest
Dieser Teil von EN 13900 legt ein Verfahren zum Bestimmen des Grades der Dispergierung eines Farbmittels in
einem thermoplastischen Kunststoff fest.
Das Verfahren ist für die Prüfung von Farbmitteln in Form von Farbkonzentraten in allen Kunststoffen geeignet, die
für Extrusions-und Schmelz-Spinn-Verfahren eingesetzt werden.
Der mit diesem Verfahren bestimmte Druckfilterwert (FPV . Englisch für filter presure value) gilt nur für die
angewendeten Geräte, die angewendeten Bedingungen und das verwendete Dispergiermedium. Die Anwendung
anderer als der festgelegten Prüfbedingungen kann zu unterschiedlichen Ergebnissen führen. Die Herstellung des
Farbkonzentrates wird in dieser Europäischen Norm nicht beschrieben. Deshalb sind die Prüfergebnisse der
einzelnen Farbmittel nur dann vergleichbar, wenn dasselbe Verfahren zum Herstellen des Farbkonzentrates
verwendet wurde.
Anhang A ist normativ und zeigt den Aufbau der Sieblochplatte.
Anhang B ist informativ und enthält ein Beispiel für einen Prüfbericht auf Grundlage eines Ergebnisses der bei der
Erarbeitung dieser Europäischen Norm durchgeführten Ringversuche.
Pigments et matieres de charge - Méthodes de dispersion et évaluation de l'aptitude a la dispersion dans les plastiques - Partie 5: Détermination de la valeur de pression du filtre lors d'un essai
La présente partie de l'EN 13900 indique une méthode permettant d'évaluer le degré de dispersion d'un pigment dans un polymere thermoplastique.
Cette méthode est utilisée pour un pigment sous forme de concentré pigmentaire (a base de polymeres) utilisé pour la coloration de polymeres dans le domaine de l'extrusion et de la fabrication de fibres.
La valeur de pression du filtre (VPF) déterminée conformément a la présente méthode n'est valide que pour l'équipement, les conditions et le polymere d'essai utilisés. La mise en ?uvre de conditions d'essai différentes de celles spécifiées peut conduire a des résultats différents. La méthode de préparation du concentré coloré n'est pas précisée dans la présente Norme européenne. Les résultats obtenus avec chacun des pigments ne sont donc comparables que si les concentrés colorés ont été préparés suivant la meme méthode.
L'Annexe A est normative et donne un modele de grille de contre-pression.
L'Annexe B est informative et fournit un modele de rapport d'essai qui présente l'un des résultats obtenus lors des essais interlaboratoires réalisés au cours de l'élaboration de la présente Norme européenne.

1 Scope
This part of EN 13900 specifies a method of assessing the degree of dispersion of a colorant in a thermoplastic
polymer.
The method is suitable for testing colorants in the form of colour concentrates in all polymers used for extrusion
and melt-spinning processes.
The filter pressure value (FPV) determined according to this method is valid only for the equipment, conditions and
test polymer being used. The use of test conditions differing from those specified might give different results. The
method of preparing the colour concentrate is not specified in this European Standard. The results obtained for
individual colorants are therefore comparable only when the same method of preparation for colour concentrates is
used.
Annex A is normative and gives a model for the breaker plate.
Annex B is informative and provides a model test report containing a result of the round-robin-tests carried out in
preparing this European Standard.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated references,
only the edition cited applies. For undated references, the latest edition of the referenced document (including any
amendments) applies.
EN 10088-1, Stainless steels – Part 1: List of stainless steels.
3 Terms and definitions
For the purposes of this European Standard, the following term and definition applies.
3.1
filter pressure value
FPV
pressure difference between the start pressure and the maximum pressure generated by extrusion in front of a
screen pack related to the amount of colorant tested
4 Principle
The test mixture, consisting of a colour concentrate and a basic test polymer, is passed through an extruder fitted
with melt pump and screen pack with breaker plate. In front of the screen pack is a melt pressure transducer. The
pressure difference between the start pressure and the maximum pressure is used to calculate the filter pressure
value [FPV].
5 Material
5.1 Colour concentrate
Homogeneous preparation of a colorant in an appropriate thermoplastic polymer.
5.2 Basic test polymer
Thermoplastic polymer, of a grade and type to be agreed between the interested parties.

NOTE The development work on this European Standard was carried out in polypropylene (PP).
5.3 Test mixture
A homogeneous mixture of a colour concentrate (5.1) and the basic test polymer (5.2) as specified in Clause 7.

6.1 General
Figure 1 illustrates the principle construction of the apparatus (see 6.2 to 6.7).

Figure 1 — Apparatus
6.2 Extruder
A single screw extruder with non-grooved barrel and a screw without dispersing elements shall be used. A screw
with a diameter between 19 mm and 30 mm and with a length of 20 L/D to 30 L/D (length/diameter) is
recommended. It is necessary to have a melt pressure transducer in front of the melt pump (A) to measure the
pressure of the melt. An electronic controller with screw speed/pressure feedback loop is necessary in order to
maintain this pressure constant, preferably at a level between 30 bar and 60 bar, to ensure that the melt pump is
completely filled and to ensure optimum homogeneity of the melt.
6.3 Melt pump
The melt pump, preferably a metering pump, shall provide a constant throughput of 50 cm³/min to 60 cm³/min.
6.4 Melt pressure transducer
The pressure range shall be preferably between 0 bar and 100 bar for mixture 1 (7.2) and between 0 bar and
350 bar for mixture 2 (7.3). The accuracy of the melt pressure transducer (B) shall be within ± 1% with a
repeatability of less than ± 0,1%.
NOTE The resolution of the pressure measurement should be 0,1 bar.
6.5 Breaker plate
A breaker plate is used to support the screen-pack and defines its free area (see Annex A).

6.6 Filter
6.6.1 General
The filter media is that part of the system which influences the differential pressure used as the basic data for
determining the results of the test.
The differential pressure increase is dependent on the retention characteristics of the filter media.
In order to have comparable results it is important that the filter media is defined in detail and assembled exactly to
specification.
Screen-packs are used as filter media. The
