A Technical Report (TR) is an informative document that provides information on the technical content of standardization work. It may be prepared when it is considered urgent or advisable to provide additional information to the CEN national members, the European Commission, the EFTA Secretariat, other governmental agencies or outside bodies.
A Technical Report is established by a CEN Technical Body and approved through a simple majority vote by the CEN national members. It involves no obligation at national level.
No time limit is specified for the lifetime of TRs, but it is recommended that they are regularly reviewed by the responsible Technical Body to ensure that they remain valid.
