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

Introduction
This Technical Specification is linked to ISO/TR 16475. ISO/TR 16475 outlines 6 basic properties
and the required performance levels of water leakage repair materials, and ISO/TS 16774 proposes a
tentative, sample testing methods that are capable of evaluating the respective properties of the repair
materials.
The test methods in this Technical Specification are intended to serve as a reference for nations that
have not yet developed a test method on the 6 required performance properties of water leakage
repair materials. If other forms of test methods that are simpler, more accurate or more organized are
available, such methods are recommended for use instead. Many of the dependent variables outlined
in the reference test methods of this Technical Specification are subject to change in accordance to
the environmental conditions (temperature and humidity, chemical solution and concentration, width
of movement activity, water pressure or water flow velocity, etc.) outlined in the standards used in
respective countries.
For ISO/TS 16774-1, ISO/TS 16774-5 and ISO/TS 16774-6, for the purpose of objectively comparing the
performance of injected repair materials, artificial cracks of same width, height, and volume were used
to control the usage of repair materials for each testing cycle and enable repetition of the same test
methods under the same conditions.

1 Scope
This part of ISO/TS 16774 specifies a laboratory test method for the qualitative determination of the
retention level of chemical resistance of repair materials in repaired cracks of concrete structures in
conditions where the material is either underwater or in contact with water that may have various
chemical components present.

The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated
references, the latest edition of the referenced document (including any amendments) applies.
ISO/TR 16475, Guidelines for the repair of water-leakage cracks in concrete structures
3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO/TR 16475 and the
following apply.
3.1
repair material for water-leakage cracks
grouting materials used to prevent water-leakages in concrete cracks
Note 1 to entry: In this Technical Specification, target ingredients are limited to injection materials outlined in
ISO/TR 16475.
4 Principle
A repair material’s resistance to chemical attacks is one of the fundamental properties that water-
leakage repair materials should possess. While repair materials can undergo chemical property
changes due to chemical attack, and moreover, harmful chemical substances can also corrode the repair
materials and reduce their repair performance in water-leakage cracks. This test method evaluates a
water-leakage repair material’s chemical resistance performance by determining if the tested material
can maintain as closely as possible its original mass after being exposed to various types of chemical
substances as a means to evaluate the material’s resistance against chemical corrosion. In this method,
comparing the mass difference of water leakage repair materials before and after chemical exposure
can be used to determine the repair material’s chemical resistance level. An example test method is
provided in Annex A.
The tested repair material sample prepared in a Petri dish is placed in a container and completely
immersed in chemical solutions for predetermined number of hours or days (values subject to change
in accordance to different national standards). The concentration of the tested chemical solution
follows the condition of the applied environment belonging to different national standards, meaning
test chemical substances that represent common chemical substances that are exposed to concrete
