3 Terms and definitions

The following terms and definitions are applicable to this document.

4 Technical requirements

4.4 The plate shall be made of industrially pure aluminum, stainless steel, rolled thin steel sheets, thermosetting plastics and other materials that are not easily damaged and deteriorated.

4.5 The Chinese characters on the plate shall generally be the simplified characters officially promulgated and implemented by the state. It is recommended to use bold, long imitation SONG [Translator note: SONG is one of Chinese fonts] and imitation SONG. The manufacturer can use the font and background color selected by itself, but the background color and the color of the text and symbols shall ensure the content of the plate to be clear, beautiful, and easy to identify. In case of special needs, traditional Chinese characters or foreign languages can be used.

4.6 The height of Chinese characters, Arabic numerals and Roman letters used on the plate shall not be less than 4 mm, and the width of the characters shall not be less than 3 mm. If the contents of the plate are printed directly on the vehicle components, the height of the printed characters shall not be less than 7 mm.

4.7 The plate shall be firmly fixed. It shall be ensured that the installed plate will be damaged once it is removed, and cannot be completely removed and used elsewhere. If tape is used to paste the plate, the item shall be etched, and the adhesive used shall be pressure-sensitive to ensure that the plate can be firmly pasted on a flat, smooth and oil-free metal or non-metal surface. For tape-attached plates, there is no need to make fastening hole locations. If a fastener-hole plate is used, as long as the plate can be firmly installed on the vehicle, the fastener hole of the plate can be made into 2 holes or 4 holes.

4.8 There shall be no obvious burrs, teeth and waves around the plate. The surface shall be flat and smooth, without cracks and obvious scratches, as well as rust spots, specks, and shadows that affect its clarity. The coating shall not have porosity, bubbles, haze, smudges, wrinkles, flaking or signs of flaking, and obvious particulate impurities. There shall be no crease marks, wrinkles, self-rolling tears, etc. on the tape-attached plates.

4.9 The fixed position of the plate shall be a part that is not easy to be worn, replaced or covered, and the specific fixed position of the plate shall be indicated in the product manual.

4.10 Each low-speed vehicle shall be at least permanently fixed with a plate on an easily visible part.

4.11 The coating adhesion of the plate shall meet the requirements of 5.5.1 in GB/T 13306-2011, and the thickness of the oxide film shall meet the requirements of 5.5.3 in GB/T 13306-2011. […]
