Why is German Cosun medical grade PPR pipe?

Germany's PPR pipes have successfully passed USP6 certification, which means that they are truly medical grade pipes. In other words, hospitals and medical equipment can be applied to the German Cosun PPR water pipe. Because the USP 6 medical device test is the most stringent test for plastics in the medical field, the test report proves that aquatherm PPR pipes will not contaminate or interfere with ongoing biological and chemical reactions, and can therefore be used in various highly sensitive areas such as pharmaceutical, and biochemical plants.
