ASTM D 2412-2002, BS EN 13598-1

Applications

QT-MMP manhole mechanical property tester is designed to determine the performance of inspection chamber, manhole frame as well as manhole wall. It can be used to test shear strength and the axial loading performance of manhole base. It can also be used to test Ring stiffness, flatness and ring flexibility test.

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 is the standard to test the mechanical performance or physical properties of pipework systems, Pipes, Drainpipes, Plastics, Unplasticized polyvinyl chloride, Polypropylene, Polyethylene, Underground, Water supply and waste systems that could be used in building, drainage, sewers and sewage engineering.

Features:

  • Gate-type structure with super high rigidity, test speed can be controlled in a large range, seamless ball bearing ensures high accuracy and stable performance
  • Digital AC servo system and piecewise linear correction method ensures the high accuracy and stability of system
  • Bridge structure of load sensors enhance the anti-bias for big pipes
  • Unique cable type inner diameter measuring system track the deformation of inner diameter. It is easy to install sample and carry out measurement
  • With protection functions of overload, over current, over face and over temperature, and multi protection methods have been set in mechanical & electrical part and software system
  • Module design satisfies customer’s requirement on extended function
