The conformity mark (also abbreviated as Ü mark ) of the federal states identifies regulated and unregulated construction products that comply with the underlying technical rule , the general building authority approval , the general building authority test certificate or the approval in individual cases. In Germany it is also known as the Ü sign, in Austria as the ÜA installation sign. The conformity mark indicates that a construction product can be used in Germany.
For construction products within the scope of a European standard, the conformity mark is replaced by the CE mark . With the CE marking, the construction product can be traded (placed on the market) throughout Europe. However, many construction products cannot be used in Germany with the sole marking of the CE mark, as further national requirements are placed on the construction product. Marking with the conformity mark is still necessary for these requirements.
With the 2014 EU Court of Justice ruling, the European Court of Justice declared the practice of “double labeling” to be inadmissible.
