Background: Ref. OSM/EE – 2007 Item No.7.1 (enclosed):* t3 k7 z6 k! Y$ n8 D! D, h
“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.
' l4 B4 r' g5 H5 N& t/ D/ J; Q- O% gWe 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.
' ?* j( Z7 W% y! U0 i5 t; F9 V* GThat cannot be a solution because many products are too small!”# n$ `+ A; I+ l; I! z
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):
4 r. J B- S i# ^% ?5 |8 pLater it was confirmed by TC108/MT2 that the book only can be used as an alternative. See explanatory notes below. Based on this it is proposed to revise decision 01/8 as amended with red text under the decision below.
% d" T2 {' \8 S p! J( v) GIt 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 1.7.2.2 O. P/ y5 F0 [" O. O+ {: ] J
Decision: This decision replaces 01/8 with the amended text in red:. K, R7 l- S, c& j. F. @

In respect of reducing the risk of ignition and spread of flame, Method 2 of 4.7.1 of EN 60950:2000 is recommended.
' D, x: |' t, l1 r' O; \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).
