YG030-1A Geotextile Apperant Opening Size Tester (Drysieving Method)

INTRODUCTION

AOS tester is used for the determination of the effective pore size of all types of geotextile products.

 

PRINCIPLE:

Using the geotextile sample as the sieve cloth, the standard granular material of known diameter is placed on the geotextile and sieved, and the diameter of the standard granular material passing through the geotextile is weighed to obtain the effective pore diameter of the geotextile product.

 

STANDARDS:

GB/T14799, ASTM D4751, JTG E50 T1144, SL/T 235
