Geotextiles and geotextile-related products. Determination of the resistance to weathering (British Standard)
This standard specifies methods for the exposure of geotextiles and geotextile-related products to weathering conditions more than those of natural weathering. The light sources used shall be fluorescent UV lamps in accordance with ISO 4892-3. This is an index test to differentiate between products with little or no resistance to weathering and those which do have this resistance.
