d1e1976-1-1__para__4
In any case, a modified product sold under the name or trademark of a natural or legal person different from the original manufacturer, should be considered as new and subject to Union harmonisation legislation. The person who carries out important changes to the product carries the responsibility for verifying whether or not it should be considered as a new product in relation to the relevant Union harmonisation legislation. If the product is to be considered as new, this person becomes the manufacturer with the corresponding obligations. Furthermore, in the case the conclusion is that it is a new product, the product has to undergo a full conformity assessment before it is made available on the market and the new manufacture’s name and contact address must be indicated on the product. However, the technical documentation has to be updated in as much as the modification has an impact on the requirements of the applicable legislation. It is not necessary to repeat tests and produce new documentation in relation to aspects not impacted by the modification. It is up to the natural or legal person who carries out changes or has changes carried out to the product to demonstrate that not all elements of the technical documentation need to be updated. The natural or legal person who carries out changes or has changes carried out to the product shall be responsible for the conformity of the modified product and draw a declaration of conformity, even if they use existing tests and technical documentation.
