6.3.1 General
In addition to the information on individual cylinders in accordance with the relevant marking regulations of the countries of use, the information specified in 6.3.3 to 6.3.5 shall be clearly identified on a corrosion-resistant plate permanently fixed on the outside of the bundle. Where there is no conflict with such regulations, all markings shall be in accordance with ISO 13769.
6.3.2 Grouping and size of marks
The following marks shall be placed in three groups:
— manufacturing marks shall constitute the top group and shall appear consecutively in the sequence given in 6.3.3;
— the middle group (see 6.3.4) shall include the test pressure, which shall be immediately preceded by the working pressure when the latter is required;
certification marks shall constitute the bottom group and shall appear in the sequence given in 6.3.5.
The minimum size of the marks shall be 5 mm.

When the country of manufacture is not the same as the country of approval, the bundle manufacturer’s mark shall be preceded by the character(s) identifying the country of manufacture as indicated by the distinguishing signs of motor vehicles in international traffic. The country mark and the bundle manufacturer’s mark shall be separated by a space or slash.
— The serial number assigned by the bundle manufacturer.
In addition, each frame shall include a unique identification number which shall be permanently marked. This number may be independent from the bundle serial number.
the test pressure in bars, preceded by the letters “PH” and followed by the letters “BAR”;
— for bundles filled by weight, the tare weight and the maximum permissible filling weight or the gross weight;
for compressed gases which are filled under pressure, the working pressure in bars, preceded by the letters “PW”;
in the case of liquefied gases, the water capacity in litres rounded down to three significant digits, followed by the letter “L”.
6.3.5 Certification marks
These shall include the following:
a reference to this International Standard;
— the character(s) identifying the country of approval as indicated by the distinguishing signs of motor vehicles in international traffic, except if the country of approval can be indicated by other means (e.g. by a specific identification number of an inspection body);
the identity mark or stamp of the inspection body that is registered with the competent authority in the country authorizing the marking;
— the date of the initial inspection, written as the year (four digits) followed by the month (two digits), the year and the month being separated by a slash (i.e. “I”).
