ČSN EN 16056

This document specifies a procedure to evaluate the passive behaviour of stainless steels and other passive alloys used in products intended to come into contact with drinking water.
The passive state is the reason why no relevant amounts of metals are released from such materials into the drinking water. This test is used to verify whether the alloy under consideration is passive under conditions which can occur in drinking waters.
This document is not applicable for product testing. It is only applicable for the assessment of passive behaviour of materials.
