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.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting
a vote.
International Standard ISO 8130-12 was prepared by Technical Committee
ISO/TC 35, Paints and varnishes, Subcommittee SC 9, General test
methods for paints and varnishes.
ISO 8130 consists of the following parts, under the general title Coating
powders:
— Part 1: Determination of particle size distribution by sieving
— Part 2: Determination of density by gas comparison pyknometer
(referee method)
— Part 3: Determination of density by liquid displacement pyknometer
— Part 4: Calculation of lower explosion limit
— Part 5: Determination of flow properties of a powder/air mixture
— Part 6: Determination of gel time of thermosetting coating powders at a
given temperature
— Part 7: Determination of loss of mass on stoving

Coating powders –
Part 12:
Determination of compatibility
1Scope
This part of ISO 8130 is one of a series of standards dealing with the sampling and testing of paints,
varnishes and related products.
It specifies a method for the determination of the tendency for the mixing of two different coating powders
to result in the deterioration of the surface quality of the final coating. The results depend on the following
characteristics of the coating powders:
a) their chemical reactivity;
b) their chemical composition;
c) their melt properties.
The onset of the deterioration in appearance, its nature and its extent will depend greatly on the ratio in
which the powders are mixed.
The test is useful in predicting the possibility of incompatibility arising from mixing different powders both
during the manufacturing process and during the application of the coating powder.
The nature of the deterioration in surface appearance may manifest itself in various ways, including:
- change in gloss level;
- the presence of pinholes, including micro-pinholes;
- the appearance of orange peel;
- the presence of craters;
- the presence of bittiness (graininess);
- the presence of colour contamination.
NOTE – Deterioration in mechanical properties may also be experienced. However, this part of ISO 8130 is
only concerned with changes in appearance.

Avant-propos
L'ISO (Organisation internationale de normalisation) est une fédération
mondiale d'organismes nationaux de normalisation (comités membres de
l'ISO). L'élaboration des Normes internationales est en général confiée aux
comités techniques de l'ISO. Chaque comité membre intéressé par une
étude a le droit de faire partie du comité technique créé à cet effet. Les
organisations internationales, gouvernementales et non gouvernementales,
en liaison avec l'ISO participent également aux travaux. L'ISO collabore
étroitement avec la Commission électrotechnique internationale (CEI) en
ce qui concerne la normalisation électrotechnique.
Les projets de Normes internationales adoptés par les comités techniques
sont soumis aux comités membres pour vote. Leur publication comme
Normes internationales requiert l'approbation de 75 % au moins des
comités membres votants.
La Norme internationale ISO 8130-12 a été élaborée par le comité
technique ISO/TC 35, Peintures et vernis, sous-comité SC 9, Méthodes
générales d'essais des peintures et vernis.
L'ISO 8130 comprend les parties suivantes, présentées sous le titre
général Poudres pour revêtement:
— Partie 1: Détermination de la distribution granulométrique par tanisage
— Partie 2: Détermination de la masse volumique à l'aide d'un
pychnomètre à gaz (méthode de référence)
— Partie 3: Détermination de la masse volumique à l'aide d'un
pycnomètre à déplacement de liquide
— Partie 4: Calcul de la limite inférieure d'explosibilité
— Partie 5: Détermination de l'aptitude à la fluidisation d'un mélange

Poudres pour revêtement —
Partie 12:
Détermination de la compatibilité
1 Domaine d'application
La présente partie de l'ISO 8130 fait partie d'une série de normes traitant de l'échantillonnage et des
essais de peintures, vernis et produits assimilés.
Elle prescrit une méthode pour la détermination de la tendance d'un mélange de deux différentes
peintures en poudre à détériorer la qualité de surface du revêtement final. Les résultats dépendent des
caractéristiques suivantes des peintures en poudre:
a) leur réactivité chimique;
b) leur composition chimique;
c) leurs propriétés de fusion.
La détérioration de l'aspect, la nature et l'étendue de cette détérioration dépendront largement du
rapport de mélange des poudres.
L'essai permet de détecter la possibilité d'une incompatibilité due au mélange de différentes poudres
pendant le processus de fabrication et l'application de la peinture en poudre.
La nature de la détérioration de l'aspect de surface peut se manifester de différentes façons:
— changement du niveau de brillance;
— présence de piqûres, y compris de micro-piqûres;
— phénomène de peau d'orange;
— présence de cratères;
— présence de grumelage (apparition de grains);
— présence d'une contamination des couleurs.
NOTE — Une détérioration des propriétés mécaniques peut aussi se produire; cependant, la présente
norme traite seulement des changements d'aspect.
