Geotextiles. Test method for the determination of the filtration behaviour of geotextiles under turbulent water flow conditions1 Scope This International Standard describes a test method for determining the soil passing through a geotextile filter when exposed to turbulent external water flow conditions. The test provides a value for one specific type of soil as a performance test for the design of erosion protection layers with geotextile filters in hydraulic engineering applications.

Assessment Conclusions

That weakness may lead to health

It applies to pipes

Aluminium-silicon-magnesium alloys consist of magnesium and silicon as the main components of the alloys

but also to demonstrate their competence in producing reference materials of appropriate quality

It should be noted that the test only describes a method to determine the resistance to crack propagation of an asphalt mixture
