Corrosion protection of steel structures by protective paint systems - Assessment of, and acceptance criteria for, the adhesion/cohesion (fracture strength) of a coating - Part 2: Cross-cut testing and X-cut testing (ISO 16276-2:2007)
ISO 16276-2:2007 specifies procedures for rating the resistance of coating systems when a cut in the form of a right-angle lattice pattern (cross-cut) or in the form of an X (X-cut) is made into the coating, penetrating through to the substrate.
It also specifies suitable equipment and defines inspection areas, sampling plans and acceptance/rejection criteria.
It does not specify ratings for particular coating systems.

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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 16276-2 was prepared by the 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.
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

ISO 16276-2:2007(E)
Introduction
The main purpose of this part of ISO 16276 is to supplement the ISO 12944 series with regard to the field
assessment of, and acceptance criteria for, the adhesion/cohesion of a coating.
NOTE This part of ISO 16276 is intended for assessment of cross-cut testing and X-cut testing of paint coatings on
steel structures on site. ISO 2409 specifies a cross-cut test and ASTM D 3359 an X-cut test for general purposes, without
instructions for interpretation of the results and without acceptance or rejection criteria.
Fracture strength testing is normally destructive and therefore requires repair work, the extent of which will
depend on the specification and on the durability required of the protective paint coating.
An objective of this part of ISO 16276 is to minimize variability and achieve uniformity of practice in the
assessment of the fracture strength of a protective paint coating and to establish acceptance/rejection criteria for
such coatings. The method uses test equipment based on the cross-cut and X-cut principles.
