Model: GT080S
Description
This tester is used to test the impervious characteristics of non-woven geotextiles (one cloth one membrane, two cloth one membrane), it’s kind of common geosynthetics testing equipment.
Test principle
When the water head pressure reaches a specific value, the sample will broken; increase the water pressure difference and keep with a certain time, when the flow increase rapidly, means that the sample is broken, thus obtain the hydrostatic pressure value, this equipment has two functions, that’s hydrostatic pressure measurement and permeability index test.
Standards
GB/T17642–1998《Composite geomembrane permeability performance test method》GB/T 17642-2008《geosynthetics non-woven composite geomembrane permeability test method》GB/T19979《Geosynthetics impervious test method》 JTG E50-2006
