Products subject to mandatory technical approval are required to undergo strict quality monitoring. IKT, as an officially designated test, monitoring and certification centre, validates the following, for example:
IKT test centre offers its customers the following services for self- and third-party monitoring to European Standards:
IKT – Institute for Underground Infrastructure
Concrete, component and method tests
Vertical-compression test on a DN500 reinforced-concrete pipe
- Pipes
- Manholes
- Special shapes
in concrete, reinforced concrete and vitrified clay, including the associated pipe joints and sealing elements and agents.
IKT also acts as a test centre for the “Güteschutz Beton NRW” (BGB) concrete quality assurance organisation.
Self- and third-party supervision
Deformation of manhole joints under vertical compressive load
- Concrete pipes, reinforced-concrete pipes, and shapes
DIN EN 1916 and DIN EN 1201 - Concrete and reinforced-concrete prefabricated manholes/manhole components
DIN EN 1917 and DIN V 4034 - Elastomer sealants
DIN EN 681 and DIN 4060 - Paving stones
DIN EN 1338 - Paving slabs
DIN EN 1339 - Kerbstones

BGB code for non-standardised concrete products
Large and diverse range of tests possible
Deformation of manhole joints under vertical compressive load
- Elastomeric pressure-transmission elements
- Vertical deformation under dynamic traffic loads is a vital factor
in accordance with the DIN V 4034, Part 1 manholes standard. - Deformation behaviour of pressure-transmission elements during pipe jacking as specified in accordance with DWA Standard A161
- Determination of sealing width, contact pressure distribution and maximum deformation
- Knowledge of contact pressure distribution is important for the development of sealing sections and of pipes
- Measurement by means of pressure-sensitive films
- in accordance with DIN EN 1916
- Injection tests on the medium-format test stand
- Injection tests for the repair of sewer laterals
- Checking of tightness against extraneous water by means of flooding of the test stand
- Service-life two months
- Tests on buried conduits
- Vertical and horizontal test forces are transmitted into a pipe simultaneously
- Highly authentic moment/normal force loads
- Actual cracking performance is reliably simulated
- Important for the assessment of crack widths and crack lengths in on-site acceptance inspection of large-calibre pipes
- Measurement of water uptake
- Visual checking of tightness
- Test pressures up to 2.5 bar
- in accordance with DIN EN 1916 and DIN EN 1201
- Exposure to vertical compressive loads
- Measurement of crack widths
- Measurement of ultimate compressive strength
- Checking of concrete cover and reinforcement
- in accordance with DIN EN 1916 and DIN EN 1201
- Tightness testing under shearing load in the pipe joint
- Visual checking of tightness
- in accordance with DIN EN 1916 and DIN EN 1201
- Bending load in the pipe-length direction
- Taking account of inadequate support
- in accordance with DIN EN 1916 and DIN EN 1201
- Quality Assurance for finished components and in-situ concrete
- in accordance with DIN EN 12390
- Checking of dimensional tolerances
- Also important for tightness
- in accordance with DIN EN 1916 and DIN EN 1201
- Resistance of external coatings
- Suitability for trenchless installation methods
- No applicable standards
- Low-shear-resistance pressure-transmission elements increase the load acting on the pipe joint
- Shear strains as a function of jacking loads
- Fundamental research
- Fluid-conducting line with radiant heat loss
- Effects on sheathing pipe often neglected
- Long-term investigations on buried sheathing pipes
- Expansion of fibre-optics networks necessary
- Installation of the “last mile” also in the pavement
- Splitter water-tightness important!
- Analysis of suitability of splitters for buried installation
