Martin,
you told me you were going to give us that list!!
I think we all together can work out a pretty good list. I believe all new and old molds from after the break 91 have the CE in mold.
It is the smurfs made and sold between 88 and 91 which are difficult to tell.
This text tell us that it was during this time the CE mark started on toys. But this was only european restrictions within EU:
"The CE mark was introduced in the beginning of the 1990's in order to give the manufacturer a way of showing that the product complies with the requirements of the directives. The CE mark means that the product can be sold freely within the EU and does not for example have to be retested in the different member states. For certain products that are regarded as particularly hazardous or that must be tested, the directives require that the manufacturer turn to one or more independent third parties, so called notified bodies. These bodies are assessed and acknowledged by the member states of the EU for testing, certification and inspection in accordance with the requirements of the different directives."
And I think it was this directive from 1988 ( 88/378/eec) for toys that started it, so before 88 I do not think they could have used it:
"The CE Marking is the manufacturer's declaration that his toys meet the essential requirements of the European Safety of Toys Directive (STD) 88/378/eec, and that such toys are therefore entitled to free movement throughout the 28 European Union & EFTA member states. The CE Marking has often been described as the "products' trade passport to Europe".
