General Introduction
Geotextile Characteristic Opening Size Test Apparatus (also name Geotextile Effective aperture tester, Pore size testing machine) is used for the determination of effective aperture of geotextile products, and its performance meets the requirements of ISO 12956:2019 Geotextiles and geotextile-related products — Determination of the characteristic opening size. And also the GB/T17634 "Determination of effective aperture of geotextile and related products -- Wet sieve method" standard for the instrument.
Main features
With the untensioned single-layer geotextile and its related product samples as a screen, under the specified vibration frequency and amplitude, the sample and graded granular material are sprayed with water, so that the granular graded material passes through the sample. The effective pore size of the specimen is indicated by the passing particle material and the specific particle size.
