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

This second edition cancels and replaces the first edition (ISO 21809-2:2007), which has been
technically revised. It also includes the Technical corrigendum ISO 21809-2:2007/Cor.1:2008.
The main changes compared to the previous edition are as follows:
Inclusion of new classifications for materials with glass transitions greater than 115°C.

Part 2:
Single layer fusion-bonded epoxy coatings
1 Scope
This document specifies the requirements for qualification, application, testing and handling of
materials for plant application of single layer fusion-bonded epoxy (FBE) coatings applied externally for
the corrosion protection of bare steel pipe for use in pipeline transportation systems for the petroleum
and natural gas industries as defined in ISO 13623.
NOTE Pipes coated in accordance with this document are considered suitable for additional protection by
means of cathodic protection.
