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 document 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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent rights
in respect thereof. As of the date of publication of this document, ISO had not received notice of (a) patent(s)
which may be required to implement this document. However, implementers are cautioned that this may not
represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.
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 Technical Committee ISO/TC 71, Concrete, reinforced concrete and pre-
stressed concrete, Subcommittee SC 6, Non-traditional reinforcing materials for concrete structures.
This third edition cancels and replaces the second edition (ISO 10406-2:2015), which has been technically
revised.
The main changes are as follows:
— — “Terms and definitions" has been revised to appropriately reflect the content of the main text.
— Figure 3— Figure 3 has been revised to appropriately reflect the content of the main text.
— — “Test report” has been revised to reflect ISO Directives, Part 2, 18.5.8.

accelerated artificial exposure testing machine
machine that creates reproducible standard test conditions to accelerate weathering artificially
3.1.2
ambient temperature
environmental conditions corresponding to the usual atmospheric conditions in laboratories with
uncontrolled temperature and humidity
Note 1 to entry: In hot and humid areas, temperature and humidity have no effect on the experimental results.

anchorage block
block corresponding to the test block to prevent bond failure of the FRP sheet
Note 1 to entry: Additional FRP sheet circumferentially jackets the block with sheets being tested to provide higher bond
strength (in this block).
3.1.4
anchoring portion
end parts of a test piece fitted with anchoring devices to transmit loads from the testing machine to the test
portion
3.1.5
bond strength
strength calculated by dividing the maximum load by the effective bond area
