GB/T17634-1998 “Determination of Effective Pore Size of Geotextiles and Their Related Products – Wet Sieve Method” ISO 12956-2004 Chinese Standard Name: Determination Characteristics of Geotextiles and Related Products

【Scope of application】: It is suitable for the determination of the effective pore size of all kinds of geotextiles and their related products. [Meet the standard]: GB/T17634-1998 “Determination of Effective Pore Size of Geotextiles and Their Related Products – Wet Sieve Method” ISO 12956-2004 Chinese Standard Name: Determination Characteristics of Geotextiles and Related Products 【Technical Parameters】: 1. Display: LCD screen, digital setting 2. Gripper inner diameter: 130mm 3. Vibration frequency: 3000 times/min 4. Screening frequency: 50 Hz 5. Amplitude: 1.5mm 6. Grid: The mesh size is (10±1)mm 7. Nozzle pressure: 300kPa, water output: 0.5L/min 8. Time: divided into two gears 0~99.99s 0～99min59s 9. Overall dimensions: 680×420×750mm 10. Weight: 45kg 11. Power supply: AC220V, 50Hz 300W 【Test Principle】: The untensioned single-layer geotextile and its related product specimens are used as screens, and the specimens and graded particle materials are sprayed with water under the specified vibration frequency and amplitude, so that the particle graded materials pass through the specimens. The effective pore size of the specimen is expressed by the passing particle material and the specific particle size.
