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.

Introduction
Thermal-barrier coatings (TBCs) are refractory coatings which provide thermal insulation for turbine blades
and vanes, as well as for combustion chamber liners in power generation, aviation gas turbines and rocket
combustors. They allow operation at substantially higher surface temperatures than is possible with bare
metal, and thus TBCs have been used to extend the life of components that suffer from severe heat load
cyclically during operation.
Conventional isothermal test methods are not suitable for evaluating the TBC under high heat load with a
large temperature-gradient condition. Standardization of a cyclic heating test method for determination of their
thermal-barrier performance and cyclic heat resistance under a temperature gradient field is required.
