EN 12226:2012 (E) 3 Foreword This document (EN 12226:2012) has been prepared by Technical Committee CEN/TC 189 “Geosynthetics”, the secretariat of which is held by NBN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by July 2012, and conflicting national standards shall be withdrawn at the latest by July 2012. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 12226:2000. The main changes compared to the previous edition are: a) the title and scope of the standard was extended from geotextiles and geotextile-related products to geosynthetics; b) normative references revised; c) new Table 1 "Sampling of specimens for tensile testing of geosynthetics after exposure" added; d) new subclause 5.4 "Compression properties" added; e) new subclause 6.3 "Change in compressive strength" added. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

Guidelines for the assessment of durability 3 Principle The test specimens are exposed to a durability test for geosynthetics. The exposure is followed by visual and, if required, microscopic inspection and by determination of changes in tensile or compressive properties, as appropriate. NOTE For further information on relevant durability tests see ISO/TS 13434. 4 Specimens 4.1 Number of specimens For each durability test the number of test and control specimens shall be a minimum of five, in both the machine and the cross-direction, unless the nature of the geosynthetic makes this inappropriate.

EN 12226:2012 (E) 5 4.2 Sampling Prepare specimens in accordance with EN ISO 9862. An overview of test methods, specimen sizes and test conditions per product type is given in Table 1. For woven and knitted geotextiles (GTX-W and GTX-K), cut pairs of test and control specimens at least

60 mm wide and 300 mm long containing the same yarns or strips in the direction of test, i.e. adjacent along t
