REHAU – RAUTITAN with
compression sleeve jointing technology
Scope
Development of a hygiene test facility and testing the
potential bacterial growth on the RAUTITAN compression
sleeve jointing technology.
Testing institute
Fraunhofer-Institut Environmental, Safety and Energy
Technology UMSICHT – Oberhausen
Hygiene test facility
The hygiene test rig consisted of four test lines with
16 test pieces using the REHAU RAUTITAN system and
was installed as a circulating ring with a thermostatically
controlled constant temperature of 30°C. The test rig
was designed as a closed loop, operating at a constant
pressure and generating a constant flow of 100l/h with
a maximum velocity of 1m/s over the total test period of
104 days. The tests took place at the test lab of Fraunhofer
UMSICHT. EVIAN mineral water was used as the test
medium. All system components were DVGW certified.
Analysis
The scientific assessment was performed by taking micro-
biological samples on all accessible connections according
to recognized analytical protocols. The determination of the
total cell count of the water samples was determined by
carrying out three decimal dilutions with buer solution.
From the original and the diluted samples 0.1ml was taken
from each and transferred onto its own culture medium.
Each culture medium was incubated at 30°C . The colonies
were counted after 72 hours (CFU per millilitre).
Conclusion – Fraunhofer UMSICHT
The tested RAUTITAN fittings showed a high tightness, which eectively prevents bacterial contamination. According to the
previous bacterial tests, such as those listed above, the REHAU compression sleeve joint can be described as a cavity-free joint.
Test period
Test start date: 23 April 2015, test finish date: 4 August 2015
Result
Overall, all joints showed
sterility compared to
germs in the water
circulation.
