This Technical Specification (CEN/TS) was approved by CEN on 21 July 2014 for provisional application.

The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to submit their
comments, particularly on the question whether the CEN/TS can be converted into a European Standard.

CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS available
promptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in parallel to the CEN/TS)
until the final decision about the possible conversion of the CEN/TS into an EN is reached.

CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,
Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,

Introduction
This Technical Specification defines a method for testing the influence of freezing-thawing cycles on the flux of
clay geosynthetic barriers. Such resistance is a requirement for many uses of these products.
The influence ratio is an indication of the behaviour of the product when exposed to repeated freezing and
thawing cycles in earth constructions. The flux of saturated clay geosynthetic barriers may increase in
consequence of repeated freezing-thawing cycles.
The Technical Specification does not purport to address all of the safety problems, if any, associated with its
use. It is the responsibili
