One of the tests in European approval procedures involves the test for Taste & Odour. It is the first and basic requirement for the approval of materials for drinking water application. This means that all legally approved materials for drinking water application in the market have met the stringent requirements of this test.
Many countries are using a so-called "Positive List" (PL) where all chemical substances used in the plastic piping system are listed. Clearly there is an interest to ensure that substances that could migrate into the drinking water do not cause harm to human health. These tests ensure that defined limit values are not exceeded and that these PL limits are established with high safety factors.
Suppliers of materials for drinking water distribution, have to meet these strict requirements, thus ensuring that only legally approved plastic materials are used for drinking water application and are classified as not harming human health with respect to listed substances of the Positive List. In several EU countries, additional tests are used or under development to further verify the highest quality level regarding the potential migration of substances into the drinking water.
The conclusions from long term experience in use and from the application of modern analytical techniques are clear. Plastic pipes that have been legally approved do not negatively affect the quality of drinking water. Moreover, they contribute significantly to its safe supply for human consumption.
