Manhole Impact Tester
Manhole Impact Tester

BS EN 13598-2:2009


QT-MIT manhole impact tester is used to test the impact performance of manhole base and manhole wall.

BS EN 13598-2:2009 Plastics piping systems for non-pressure underground drainage and sewerage. Unplasticized poly (vinyl chloride) (PVC-U), polypropylene (PP) and polyethylene (PE). Specifications for manholes and inspection chambers in traffic areas and deep underground installations. 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.


  • Vacuum system is introduced to lift the weight, with big suction and high efficiency
  • With the functions of measuring instantaneous impact velocity, automatic catching impact weight and anti-rebounded
  • System frame with the adjustable cantilever structure and open test space, makes it easier for sample installation
  • Actions before impact: the weight is lifted into the protection tube by suction, then the protection tube is fixed automatically at a position of the sow channel center, click “impact” button to release the impact weight.
  • Actions after impact: the weight is caught automatically and lifted into the protection tube again
  • Protection tube is installed vertically and with the internal wall roughness less than 0.8. The friction is very low which ensure the real impact velocity no less than 95% of theoretical value
  • Protection tube location checking system is installed at the bottom of protection tube, which ensures the tube stop at the position of 50mm above the impact point on sample; also the position can be controlled at any point on customer’s requirement
  • Dual redundancy design of the limit sensor ensures more safety control
