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.

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/

This document was prepared by Technical Committee ISO/TC 107, Metallic and other inorganic coatings.
This third edition cancels and replaces the second edition (ISO 6370-2:2011), which has been technically
revised. The main changes compared with the previous edition are as follows:
— terms and definitions have been added;
— sanidine (potassium feldspar) has been included as an additional abrasive option for testing;
— the requirements for steel balls have been amended.
A list of all parts in the ISO 6370 series can be found on the ISO website.

ISO 6370-2:2020(E)
Introduction
Extensive tests have shown that, with the comparative method described in this document, the
uncertainty of measurement of test results is ± 5 %. Furthermore, absolute quantities for the amount
of wear give little information, because abrasives used in practice differ considerably in their effect on
enamelled surfaces. Each abrasion test with a standardized method can only be carried out with the
aim of providing a general classification of various vitreous and porcelain enamels in relation to each
other. Absolute quantities for the amount of wear are therefore not required.
Numerous tests have shown that the three required test periods of 30 min were sufficient to obtain
comparable results. If the vitreous and porcelain enamel coat to be tested is thicker than 0,2 mm, it is
not necessary to determine the loss in mass after each 30 min test period, because the abrasion under
the conditions described in this document is directly proportional to the test duration.
