LIGHT TRANSMISSION

As there is no specific standard, we have built an experimental device according to American Standard ASTM D1494-12 "Standard Test Method for Diffuse Lifht Transmission Factor of Reinforced Plastics Panels" that it measure the light transmission coefficient through the agrotextiles.

The apparatus for this test method is composed by a test cabine, a photo-radiometer with different sensors and a light source.

WATER PERMEABILITY

To obtain the water permeability to through the agrotextiles, we have made an experimental device according to the standard UNE-EN ISO 11058 "Determination of the water permeability characteristics perpendicular to the plane".
