I. Implementation Timeline
◆Jan 1, 2027: New regulations take effect (subject to possible delay)
◆Dec 31, 2032: Transition period ends, with full implementation across all EU member states
II. Material Compliance Requirements
(1). Non-metallic materials
◆Formulation reviews must comply with the EU Positive List (EU2024/367)
◆Testing standards similar to German KTW-BWGL
New chlorine-containing water extraction test
(2). Metal Materials
◆Use metal grades and composition standards listed in the EU Positive List (EU2024/367)
◆Copper alloys such as CW617N/CW511L have been removed from the EU Positive List (EU2024/367)
◆German exception: Use of CW511L-DW low lead (lead <0.1%) is permitted, with future inclusion in the EU Positive List (EU2024/367) anticipated
III. Recommendations for Businesses
(1). Metal Materials
German Market:
◆After January 2028: Commonly used metal materials such as CW617N/CW511L (lead <0.2%) may no longer be included in products newly installed in water supply systems;
◆Updates and applications for DVGW and KTW-BWGL certificates should consider new alternative metal grades;
Other EU Countries:
◆The 4MS metal grades will continue to be used; new European certification applications can be considered to gradually replace non-listed materials such as CW617N;
◆Existing certificates can consider alternative metal grades, but the impact on product certification certificates such as DVGW/CSTB/KIWA must be evaluated;
Recommended alternative materials:
-1- European standard stainless steel (1.4301/1.4404)
-2- Brass (CW024A)
-3- CW511L-DWlowlead (lead <0.1%)
-4- Or other EU positive list component grades
(2). Non-metallic materials
◆DWD formulation review and testing can be conducted in advance
◆Official DWD certification will be issued after 2027 (currently no authorized certification body)
