Static Constant Loading Tester for Thermoplastic Manhole

QT-RST200-3000-EXT Static Constant Loading Tester is mainly used to determine the resistance to the axial static constant load of plastic manhole. A constant force is steadily loaded on the axial direction of the manhole for the specified time, when the test is finished, observing the sample appearance (deformation, collapse, crack or crazing), determine the deformation in axial direction and calculate the deformation ratio of manhole. The machine is also suitable for ring stiffness test, flattening test, ring softness test of thermoplastic pipes.

BS EN 13598-1:2003 Plastics piping systems for non-pressure underground drainage and sewerage. Unplasticized poly (vinyl chloride) (PVC-U), polypropylene (PP) and polyethylene (PE). Specifications for ancillary fittings including shallow inspection chambers. It gives definitions and requirements for ancillary fittings of PVC-U, PP, and PE that can be used in non-pressure underground drainage and sewerage systems either outside the building structure or buried in ground within the building structure.
