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 4534 was prepared by Technical Committee ISO/TC 107, Metallic and other inorganic coatings.
This second edition cancels and replaces the first edition (ISO 4534:1980), which has been technically revised.
The revised edition allows for the use of flow plates, other than unglazed ceramic tiles, such as enamelled
steel or cast iron which is common practice in some countries.

Introduction
The fusion flow test specified in this International Standard is a comparative method which can be carried out
with simplified equipment to provide data on the fluidity behaviour of molten enamel. The results from this test
allow conclusions on the flow properties of the enamel to be inferred in a much simpler manner than is
possible from the results of the much more expensive measurements made using the usual viscosity-
measuring instruments.
1)
The results of extensive tests have shown that there is a well-defined relationship between the results of the
flow test and the viscosity-temperature curve, so that the flow test could also be used as an absolute method.
However, more effort would be required to enable the various laboratories to obtain comparable results of
similar quality than when using the method for comparative purposes.
When using this method, the reference (comparison) enamel must be similar to the enamel to be tested, as
the fluidity behaviour of the various types of enamel might vary considerably from one type to another.
