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 non­governmental, 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.

Introduction
The forming properties of sheet metals are highly dependent on the friction that is generated with the
dies during the forming process.
Therefore, there is a need to measure the frictional characteristics of the surface of sheet metals.
The measured friction coefficient can change depending on the test conditions and the apparatus
status. Moreover, if the apparatus has been configured properly, it is difficult to ensure reliability and
reproducibility. Many traditional methods cause deformation or breakage of the test pieces because of
the pressure of the friction block (and its perpendicular pressure to the specimens). In addition, there
is no International Standard for metallic coatings, other inorganic coatings and chemical conversion
coatings.
This document gives an advanced method that can accurately measure the friction coefficient without
deformation of the test pieces during the test.
The test results can vary depending on the test conditions, e.g. surface state, normal force, sliding
velocity, temperature. Therefore, it is important that the test conditions are specified.
The International Organization for Standardization (ISO) draws attention to the fact that it is claimed
that compliance with this document may involve the use of a patent related to the composition of
apparatus given in Clause 4.
ISO takes no position concerning the evidence, validity and scope of this patent right.
The holder of this patent right has assured ISO that he/she is willing to negotiate licences under
reasonable and non-discriminatory terms and conditions with applicants throughout the world. In
this respect, the statement of the holder of this patent right is registered with ISO. Information may be
obtained from the patent database available at www .iso .org/ patents.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights other than those in the patent database. ISO shall not be held responsible for identifying
any or all such patent rights.

Metallic and other inorganic coatings — Test method
for the friction coefficient measurement of chemical
conversion coatings
1 Scope
This document specifies a test method to measure the friction coefficient of chemical conversion
coating sheet products and coiled products.
This document is applicable to measure or compare the friction properties of hot­dip galvanized,
lubricated and resin coated steel sheet, when tested under the same conditions.
