        YT030 geotextile effective aperture tester(dry screening)

        Applicable scope
        Test principles and standards
        Instrument characteristics
        Configuration list

        Used for the determination of the effective pore size of various geotextiles and related products.

        GB/T 17634-1998 geotextiles and geotextile-related products-deter-mination of effective pore size-wet sieving method
        SL 235-2012 Test code for geosynthetics

        The specimen is made of non tension single layer geotextile and its related products as sieve mesh, and the particle and the graded particle material are sprinkled under the prescribed vibration frequency and amplitude, so that the particle gradation material passes through the sample. The effective pore size of the sample is expressed by the particle material and the specific particle size passed through.
