This standard specifies a method forThe determination of the microbiological resistance of geotextiles and geotextile-related products by a soil burial test. It does not specify for which products or in which applicationsThe soil burial test is required.NOTE 1:For further reference, see CR ISO 13434.NOTE 2:Experience and exhumation of geotextiles and geotextile-related products which had performed successfully, in some cases for more than two decades, indicate that geotextiles and geotextile-related products made out of synthetic materials are generally resistant against microbially initiated decay. It canTherefore be expected that most of these products commercially available atThe present time will passThe soil burial test successfully and it is probably not necessary to submitThem all toThis test independent of their function. However, ifThe requirements for appropriate functioning of the geotextiles and geotextile-related products demand proof of microbiological resistance or ifThey are manufactured from newly developed polymers whose resistance is in any doubt,The soil burial test should be performed
