Background: Ref. OSM/EE – 2007 Item No.7.1 (enclosed):
% q2 l7 O/ r6 x$ U4 ]- A“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.: c% R+ L' _; w4 e9 h
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.* r( \" D5 j3 U, k" d
That cannot be a solution because many products are too small!”
7 `. L: [" E/ x. s7 {% I) u5 gOSM/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):
& t+ \2 u- w2 Q* |( k6 E2 HLater 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.) ~) u" v! c" \
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.
+ i& n$ H: A0 FDecision: This decision replaces 01/8 with the amended text in red:

"For applicable power supplies see user instructions". This statement shall also be in the user-instructions.

In respect of reducing the risk of ignition and spread of flame, Method 2 of 4.7.1 of EN 60950:2000 is recommended.! e) D; r. I9 A9 g
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).- n* W& T% ^7 t2 q; C
