Background: Ref. OSM/EE – 2007 Item No.7.1 (enclosed):3 o- c3 {! R5 d+ k1 g8 q
“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.
; s* N% Z" X) G! s- s* C1 ?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.
! @* \4 S; x! y/ ~2 r9 j2 kThat cannot be a solution because many products are too small!”( C: h% O9 i; M n
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):8 H+ S! M, R( ^; n
Later 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.6 G+ }; E1 V9 x
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.. Y' v2 L7 \1 D2 Q$ Z7 O- T
Decision: 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.0 i$ h$ ^# S j; x8 b
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).% X B, Y" t; @, |6 K% i
