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

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 test 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 references 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.

Test methods for repair materials for water-leakage cracks

Test method for water (wash out) resistance
1 Scope

This part of ISO/TS 16774 specifies a laboratory test method on the quantitative determination of repair

material’s performance and resistance against erosion and wash out due to underground water flow.

2 Normative references

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.
[SOURCE: ISO/TS 16774-2:—, 3.1]
4 Principle

Resistance to water flow is one of the fundamental properties that water-leakage repair materials

should possess. Repair materials are, in most cases, under constant pressure due to water flow, meaning

there are risks of erosion, and/or washout and eventual reopening of leakage paths. This test method

evaluates the performance of repair material for water-leakage crack by observing how closely the

materials can maintain their original state after being exposed to long term water flow. This is done by

comparing the mass difference of water-leakage repair materials before and after flow testing in order

to determine the repair material’s wash out resistance. An example test method is provided in Annex A.

Test repair material is placed in a Petri dish container, which is then placed under exposure to water

flow for predetermined duration in a water flow chamber apparatus (flow velocity, duration of flow

testing, and other relevant conditions are subject to change in accordance regulated values and figures

outlined in different national standards). The mass of the test specimen prior to and after the exposure

to water flow is measured using an electronic scale and the data is recorded. For th
