Plastic ball indentation hardness tester

• 

The Plastic Ball Indentation Hardness Tester is a precision instrument designed to evaluate the mechanical and hydraulic performance of plastic drainage plates under specified pressures and water flow conditions. It measures seepage characteristics while applying lateral pressure and a defined hydraulic gradient, providing critical data for material selection, quality control, and design validation in civil engineering, construction, and drainage systems.

Application

(1) Testing the plane-direction seepage characteristics of plastic drainage plates under lateral pressure.

(2) Evaluating the hydraulic performance of drainage materials for civil engineering and construction applications.

(3) Quality control of plastic core plates used in drainage boards, geocomposites, and waterproofing systems.

(4) Research and development of new plastic drainage materials with improved mechanical and seepage performance.

(5) Assessing the effect of lateral pressure and hydraulic gradient on water flow through drainage materials.

(6) Calibration and verification of design parameters for drainage structures in tunnels, roads, and landscaping projects.

Standards

(1) JTG E50 T1143-2006 — Technical specification for drainage plate testing in highways.

(2) SL/T — Laboratory method for measuring water permeability of drainage materials.

(3) JT/T 521 Appendix A-2004 — Standard for plastic core plates in drainage applications.

(4) JTS-206-1 Appendix B B.3-2009 — Test method for plastic geocomposite materials.

(5) JTS/T 245-2023 — Hydraulic performance testing of drainage plates.

(6) ISO 12958 — Determination of water permeability of geosynthetics (comparable international standard).
