0 Comment

In order to offer best rainwater harvesting modular and service to customers from all over the world, recently Leiyuan Industrial Company Limited send components for fabrication of Rainwater Harvest Modular underground stormwater storage chambers to TRI Environmental, Inc. for testing and analysis.

The samples were sent and tested under TRI log number E2402-31-10. Compression testing was based on a bench-scale compression test, ASTM D2412, Standard Test Method of the Determination of External Loading Characteristics of Plastic Pipe by Parallel-Plate Loading. The test method was modified to apply the compressive load at a constant rate of 2.0% of the height of the chamber per minute as directed in ASTM F2418, Standard Specification for Polypropylene (PP) Corrugated Wall Stormwater Collection Chambers and ASTM F2922, Standard Specification for Polyethylene (PE) Corrugated Wall Stormwater Collection Chambers. Compression testing was conducted on an Instron Model 5885 Tensile/Compression Testing Machine equipped with a 45k pound capacity load cell and Blue Hill data acquisition software. Reinforced aluminum loading platens, measuring 21 inches by 33 inches, were used for applying the compressive load. Load was applied until specimen failure.
