Buckling Resistance Tester for Thermoplastic Drainage Cover Application
QualiBRT-14830 Buckling Resistance Tester for Thermoplastic Drainage Cover is used to simulate the conditions when manhole is buried underground and for checking its resistance to the force from underground water.
Seal and vacuumize the sample at a temperature between 20℃-25℃, ensuring internal negative pressure remains stable for over 1000 hours. Measure the deformation of the flow channel side and bottom, then extrapolate the deformation after 50 years using the least squares method.
BS EN 14830:2006 Thermoplastics inspection chamber and manhole bases. Test methods for buckling resistance. It is a standard testing method to test the buckling resistance for Manholes, Thermoplastic polymers or Pipes, etc. which would be used in underground water supply and waste systems (building, drainage, sewerage).
