identical text or by endorsement, at the latest by September 2026, and conflicting national standards shall
be withdrawn at the latest by March 2029.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 30-1-4:2012.
This document has been prepared under a standardization request addressed to CEN by the European
Commission. The Standing Committee of the EFTA States subsequently approves these requests for its
Member States.
For the relationship with EU Legislation, see informative Annex ZA, which is an integral part of this
document.
The main modifications in this document with respect to the previous edition (EN 30-1-4:2012) are the
