Background: Ref. OSM/EE – 2007 Item No.7.1 (enclosed):
X3 F/ q$ u# |7 G“OSM decision 01/8 requires markings on the product (e.g. "Use only power supplies listed in the user manual / user instruction." or “For applicable power supplies see user instruction”). Furthermore such sentences shall be in the languages acceptable to the country where the product will be used.( _4 }! L# i( Y; [/ l
We cannot assume that all people speak or understand English and therefore it is necessary to put nearly all languages of such relevant safety instructions on the product.
& O5 O" a) X' q, t: qThat cannot be a solution because many products are too small!”
- A) c. G" n# c# w0 a) ~OSM/EE-2007 agreed to use instead of such instructions (sentences) on the product, international accepted symbols like these both marks (ISO 7000-0434 and ISO 7000-1641):

3 X" B5 |" x4 zIt may be considered that the Decision 99/2, requiring marking of manufacturer and model of the power supply on the product, is too stringent in light of sub clause 1.7.2.

The user instructions must then have a listing of manufacturers and models of the relevant power supplies.& D; f$ L8 x! g' w$ D; g
In respect of reducing the risk of ignition and spread of flame, Method 2 of 4.7.1 of EN 60950:2000 is recommended.9 S Q# r) P$ H% ~) W
As an alternative to the text on the product, it is acceptable to use both the symbols ISO 7000-0434 and ISO 7000-1641. The book alone is also sufficient (ISO 7000-1641).
