Introduction
This document is linked to ISO/TR 16475. ISO/TR 16475 outlines six basic properties and the required
performance levels of water leakage repair materials, and the ISO/TS 16774 series proposes sample
testing methods that are capable of evaluating the respective properties of the repair materials.
The test methods in this document are intended to serve as references for nations that have not yet
developed a test method on the six 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 document are subject to change in accordance with 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.

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 materials for water-leakage cracks 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.
The 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 with regulated values and
figures outlined in different national standards). The mass of the test specimen prior to and after the
