1.Description:
The tester is applicable to the test method for determining the
water permeability coefficient of permeable pavement bricks and
permeable pavement panels as specified in GB/T25993-2010 "Appendix
C - Test Method for Water Permeability Coefficient of Permeable
Pavement Bricks and Permeable Pavement Panels". This instrument is
mainly composed of a water tank, an electrical control box, sample
fixtures, a platform, and other components. The sample fixture is
suitable for samples with a cylindrical cross-section. The fixture
ensures that during the test, the liquid can only pass through the
pores on the surface of the sample without leaking from the edges
of the sample.
2.Working principle
Permeability coefficient: The ability of a material to allow liquid
to pass through under a certain pressure difference.
