The size of the Mark may be reduced or enlarged on the condition that it remains readable and that the proportions ofwidth and height are kept. The use of dark text for the D-Mark on light backgrounds and light text on dark backgrounds ispermitted.
The D-Mark may appear on a label, nameplate, or may be cast, stamped or molded into the product. When appearing ona label or nameplate, the Manufacturer’s name or trademark along with a model number are also required on that samelabel or nameplate. If cast, stamped or molded, the Certificate Manufacturer’s name or trademark and model number shallalso appear elsewhere on the product
When putting the product on the EU market, the manufacturer’s name, trademark or mark of origin must be affixed in aclearly visible location and position on the product, on the package and in the user manual. It can be affixed by label, be
directly imprinted, or cast or molded into the product.
Where the size of the product does not allow the Mark, the manufacturer’s name, trademark, mark of origin and model
number to be legible, and appearance on a label is not desired, it is allowed to cast, stamp or mold the Mark into the
product, in a size which is not visible to the naked eye, provided the legible Mark, the manufacturer’s name, trademark or
mark of origin and model number appears on the package and in the user manual
