Background: Ref. OSM/EE – 2007 Item No.7.1 (enclosed):
6 J# I/ w3 q# V* Z3 Y$ B“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.
; ?2 O7 b3 f! X/ \$ {+ j' h- sWe 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.
& V% |# P! w% _; WThat cannot be a solution because many products are too small!”
4 J1 s/ X: v( W% r1 g$ ~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):

It 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.( A0 m$ m# d! @; n

In respect of reducing the risk of ignition and spread of flame, Method 2 of 4.7.1 of EN 60950:2000 is recommended.
