Pore openings of thin geotextiles, and in particular knitted geotextiles, can be observed with a microscope. The proposed standard will propose a methodology to capture images of the pores, and to process them to determine the properties of the pores.
The title and scope are in draft form and are under development within this ASTM Committee.
