BS EN 12226:2012

What is BS EN 12226 - Geosynthetic durability test about?

BS EN 12226 is a European standard that focuses on general tests for the evaluation of geosynthetic durability testing. BS EN 12226 specifies test methods for determining the change in specific properties of aged geosynthetics.

Who is BS EN 12226 - Geosynthetic durability test for?

BS EN 12226 on general tests for the evaluation of geosynthetic durability test is useful for:

• Design engineers
• Entities involved in quality and assurance of geosynthetic durability
• Operational control managers
• Geosynthetic lab operators

Why should you use BS EN 12226 - Geosynthetic durability test?

Geosynthetics, mostly used in civil engineering applications, are designed to provide service over the specified design period. BS EN 12226 provides a procedure for the determination of shrinkage of geotextile fabrics when exposed to elevated temperatures. The effect of the temperature is expressed as a percentage decrease in the area of the geotextile.

BS EN 12226 sets out a method for determining the durability of geotextiles when subjected to degradation due to exposure to light and heat by artificial means.

BS EN 12226 evaluates the deterioration in tensile strength and strain after outdoor exposure.  The deterioration is assessed as a reduction in strength and strain at failure from the unexposed geotextile.

With the help of BS EN 12226 guidelines, you will be able to improve the quality of geosynthetics.

What’s changed since the last update?

BS EN 12226:2012 supersedes BS EN 12226:2000. BS EN 12226:2012 includes some technical changes concerning BS EN 12226:2000. These include:

• The title and scope of the standard was extended from geotextiles and geotextile-related products to geosynthetics
• normative references revised
• New Table 1 "Sampling of specimens for tensile testing of geosynthetics after exposure" added
• New subclause 5.4 "Compression properties" added
