The gradual increase in the number of substances to be analyzed causes a need for more pipe samples. When analyzing for more substances, more migration water and thus also more pipe pieces must be used. There can be difference in how much migration water is to be used, some analyzes require a lot of water, and there must also be a little extra pipe samples left, in case a re-test is to be done.

It is crucial for the test result when retesting that the pipes are produced from the same batch. Therefore, it has been decided to increase the number of pipe samples to be sent to the laboratory for testing.
