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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. 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.
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.
ISO 4625-1 was prepared by Technical Committee ISO/TC 35, Paints and varnishes, Subcommittee SC 10,
Test methods for binders for paints and varnishes.
It cancels and replaces ISO 4625:1980, which has been technically and editorially revised to harmonize it with
ASTM E 28-99, Standard Test Methods for Softening Point of Resins Derived from Naval Stores by Ring-and-
Ball Apparatus. The main changes are the introduction of an automated procedure and the splitting of the
softening point values into four ranges: less than 35 °C, 35 °C to less than 80 °C, 80 °C to 150 °C and greater
than 150 °C. The moulding method for the preparation of test pieces has been deleted.

point —
Part 1:
Ring-and-ball method
1 Scope
This part of ISO 4625 specifies methods of determining the softening point of resins (including rosin) and
similar materials by means of the ring-and-ball apparatus.
Both manual and automatic methods are specified.
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.
ISO 5725-1, Accuracy (trueness and precision) of measurement methods and results — Part 1: General
principles and definitions
ISO 15528, Paints, varnishes and raw materials for paints and varnishes — Sampling
IEC 60751, Industrial platinum resistance thermometer sensors
ASTM E 691, Standard Practice for Conducting an Interlaboratory Study to Determine the Precision of a Test
Method
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
softening point
temperature at which a disc of sample held within a horizontal ring is forced downward a distance of 25,4 mm
under the weight of a steel ball as the disc is heated at a prescribed rate in a water, glycerol, silicone oil,
ethylene glycol/water or glycerol/water bath
4 Principle
In general, with materials of the types mentioned in Clause 1, softening does not take place at a definite
temperature. As the temperature rises, these materials gradually change from brittle or exceedingly thick and
slow-flowing materials to softer and less viscous liquids. For this reason, the determination of the softening
point must be made by a fixed, closely defined method if the results obtained are to be comparable.

SIST EN ISO 4625-1:2006
ISO 4625-1:2004(E)
In these test methods, the softening point is defined as the temperature at which a disc of the sample held
within a horizontal ring is forced downward a distance of 25,4 mm under the weight of a steel ball as the
sample is heated at 5 °C/min in a water, glycerol, silicone oil, ethylene glycol/water or glycerol/water bath.
5 Sampling and preparation of test pieces
5.1 Sampling
Take a representative sample of the product to be tested, as described in ISO 15528.
The sample shall consist of freshly broken lumps free of oxidized surfaces. For samples received as small
lumps, scrape off the surface layer of the lumps immediately before use, avoiding inclusion of finely divided
material or dust.
5.2 Preparation of test pieces by the pour method
5.2.1 Field of application
This preparation procedure is suitable for resins (including rosin) and other substances that can be heated
and poured without adverse effects on the softening point.
5.2.2 Apparatus
5.2.2.1 Container, in which the sample can be melted.
5.2.2.2 Knife or spatula.
5.2.2.3 Oven, hot-plate, sand bath or oil bath.
5.2.3 Procedure
Take a quantity of the sample (see 5.1) which is at least twice that necessary to fill the desired number of
rings (7.1.1), but in no case less than 40 g, and melt it immediately in a clean container (5.2.2.1) using an
oven, hot-plate, sand bath or oil bath (5.2.2.3) to prevent local overheating. Take care to avoid incorporating
air bubbles in the sample. Melt the sample completely, but do not heat it above the minimum temperature
necessary to pour it easily. The time from the beginning of heating to the pouring of the sample shall not
exceed 15 min.
For materials that are heat-sensitive, continuously inert the atmosphere in the container holding the sample
with nitrogen (N ) during the melting procedure.
2
For materials that tend to crack or shrink in the rings on cooling, preheat the rings immediately before filling
them to approximately the temperature at which the material is to be poured. The rings, while being filled, shall
rest on a suitable metal surface. Pour a sufficient quantity of the sample into the ring so as to leave an excess
on cooling. Allow to cool for at least 30 min and trim off the surplus material at the periphery of the ring. To
remove excess material from the top, cut the excess material off cleanly with a slightly heated knife or spatula
(5.2.2.2) or grasp the ring in a pair of tongs and draw the top surface of the test piece quickly and firmly over
the surface of a heated metal plate. If the determination is repeated, use a clean container and a fresh
quantity of the sample.

5.3 Preparation of test pieces from samples having a low softening point (up to 35 °C)
5.3.1 Apparatus
5.3.1.1 Aluminium foil.
5.3.1.2 Dry ice or freezer.
5.3.1.3 Knife or spatula.
5.3.2 Procedure
Take a suitable quantity of the sample (see 5.1). Place one of the rings (7.1.1) on a piece of aluminium foil
(5.3.1.1). Pour the material to be tested into the ring. Then place the foil and filled ring on dry ice or in a
freezer (5.3.1.2) to cool. The material in the ring shall be free of bubbles.
After cooling, cut or scrape off any excess material using a slightly heated knife or spatula (5.3.1.3), then slide
the ring gently from the foil. Place the ring in the ring holder (7.1.8) and immediately perform the softening
point determination as described in 7.3.
6 Materials (heating-bath liquids)
6.1 Distilled or deionized water, freshly boiled, for softening points between 35 °C and 80 °C
Use freshly boiled water that has been cooled to at least 27 °C below the anticipated softening point, but not
lower than + 5 °C. The use of f
