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

This document was prepared by Technical Committee ISO/TC 107, Metallic and other inorganic coatings,
in collaboration with the European Committee for Standardization (CEN) Technical Committee CEN/
TC 262, Metallic and other inorganic coatings, including for corrosion protection and corrosion testing of
metals and alloys, in accordance with the Agreement on technical cooperation between ISO and CEN
(Vienna Agreement).
This second edition cancels and replaces the first edition (ISO 13807:1999), which has been technically
revised. It also incorporates the Technical Corrigendum ISO 13807:1999/Cor 1:2000.
The main changes are as follows:
— the normative references have been updated;
— the method for measuring coating thickness has been updated;
— the thickness requirements for the vitreous enamel coating have been updated;
— the specimen heating temperature requirements have been updated.
Any feedback or questions on this document should be directed to the user’s national standards body. A

INTERNATIONAL STANDARD ISO 13807:2022(E)
Vitreous and porcelain enamels — Determination of crack
formation temperature in the thermal shock testing of
enamels for the chemical industry
1 S cope
This document specifies a test method for the determination of the crack formation temperature of
enamels for the chemical industry by subjecting enamelled steel specimens to thermal shock using cold
water.
The value of the crack formation temperature measured according to this test method does not apply to
the finished component (see Annex A). It is a parameter of vitreous and porcelain enamels for comparing
the relative quality of different enamel formulations.
