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.

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/iso/foreword.html.
This document was prepared by European Committee for Standardization (CEN) Technical Committee CEN/
TC 139, Paints and varnishes, in collaboration with Technical Committee ISO/TC 35, Paints and varnishes,
Subcommittee SC 14, Protective paint systems for steel structures.
This second edition cancels and replaces the first edition (ISO 16276-2:2007), which has been technically
revised.
The main changes are as follows:

A list of all parts in the ISO 16276 series can be found on the ISO website.
ISO 16276 consists of the following parts, under the general title Corrosion protection of steel structures by
protective paint systems — Assessment of, and acceptance criteria for, the adhesion/cohesion (fracture strength)
of a coating:
— Part 1: Pull-off testing
— Part 2: Cross-cut testing and X-cut testing
