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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see www .iso
.org/iso/foreword .html.
This document was prepared by Technical Committee ISO/TC 35, Paints and varnishes.
This third edition cancels and replaces the second edition (ISO 4619:1998), which has been technically
revised. The main changes compared to the previous edition are as follows:
— the concentration of phenolphthalein indicator solution in 7.7.2.6 has been reduced to 0,5 % following
actual requirements;
— the determination of lead has been deleted;
— the normative references have been updated;
— the text has been editorially revised.
Any feedback or questions on this document should be directed to the user’s national standards body. A
complete listing of these bodies can be found at www .iso .org/members .html.

4 Descriptions
4.1 Solid driers
Solid driers are materials which can be manufactured in a hard, soft (highly viscous) or powder form.
4.2 Liquid driers
Liquid driers are materials which are supplied as solutions in organic solvents, usually white spirit.
All these types of driers, when dissolved in solvents (normally hydrocarbons), impart specific drying
properties depending on the metal used.
4.3 Metals used
The following metals are normally used: cobalt, manganese, zinc, calcium, cerium (or other rare earths),
iron, zirconium, vanadium, barium, aluminium, strontium, etc.
NOTE In this document, methods for determination of metal content are given only for those metals which
are in common use.
4.4 Acids used
The following acids are used: fatty acids of linseed oils, tall-oil fatty acids, resinic acids, naphthenic
acids, 2-ethylhexanoic acid, fatty iso-acids with 9 carbon atoms, other fatty acids with 9 to 11 carbon
atoms, etc.

5.2 Driers named according to the commercial name of the main acid used shall contain at least 90 %
of this acid, except for driers based on naphthenic acids, which shall contain at least 70 % of these acids,
expressed as a percentage of the total mass of acid present.
NOTE The type and content of the acids can be determined by gas-chromatographic (GC) analysis, except in
the case of naphthenic acids.
6 Sampling
Take a representative sample of the drier to be tested, as specified in ISO 15528.
7 Methods of test for solid driers
During the analysis, use only reagents of recognized analytical grade and only water of at least grade 3
purity in accordance with ISO 3696.
7.1 Appearance and consistency
Examine the sample visually for uniformity. If the consistency is specified, a method for its
determination shall be agreed between the interested parties.
7.2 Colour
Dissolve 1 part by mass of the drier in 1 part by mass of white spirit or other agreed solvent and
compare the colour against an agreed sample or colour standard.

7.3 Solubility (miscibility) in solvents, raw linseed oil or other drying media
Slowly heat, raising the temperature at a rate of 1 °C/min, 5 g of the drier and 20 g of an agreed solvent
(or drying medium) under reflux on a sand bath, with stirring, until a homogeneous solution is obtained.
Allow to cool to room temperature and examine the solution for clarity, clouding and any separation or
deposit.
7.4 Stability of solution
Allow 3 portions of the solution obtained by the method specified in 7.3 to stand for 7 days in stoppered
bottles, one at each of the following temperatures:
a) 0 °C;
b) ambient temperature;
c) 50 °C.
After 1 day and again after 7 days, examine the solutions for clarity, clouding sedimentation or gelation.
The bottle used for the test at 50 °C shall be able to withstand the pressure generated.
7.5 Suspended solid matter
Weigh, to the nearest 0,1 g, 5 g of solid drier (or 10 g of liquid drier) into a glass flask and dissolve in
(or dilute with) 100 g of white spirit or an agreed solvent. Stopper the flask, allow to stand at ambient
temperature for 3 days, then filter off the sediment or suspended matter using a glass filter crucible of
porosity P 16 (see ISO 4793). Wash the residue on the filter with the solvent and dry it at 105 °C for 3 h.
Cool to ambient temperature and weigh to the nearest 1 mg.
Calculate the suspended solid matter SSM, as a percentage mass fraction, using Formula (1):

7.6 Volatile matter
Proceed in accordance with ISO 3251, taking a flat-bottomed glass of aluminium dish and a test portion
of (1,00 ± 0,02) g. Place the dish with the test portion in the air oven, maintained at (105 ± 2) °C. Leave it
in the oven at this temperature for 3 h.
7.7 Acidity
7.7.1 Principle
A solution of the drier in toluene/propan-2-ol is passed through a strong acid cation exchanger and the
total acid in the eluate is determined. From the total acid determined, the acid combined with the metal
is subtracted.
If a negative value for the acidity is obtained, the
