Companies that place products on the EU market always have to fulfil at least the following two obligations:
The technical file shall cover the relevant information about the assessment and the description of the product itself.
In practice a technical file contains at least the following elements:
Whenever asked by a national authority the relevant parts of the technical file must be provided to that authority by the company that places the product on the market.
In many cases the compliance evidence such as test reports is provided by the supplier. The tests have been performed on his behalf. The test reports will refer to his company and to the product reference of the supplier.
This product reference in the test reports may deviate from the product identification and description that is used by the buying company that markets the product under his own model or type reference.
It is important to realise a link, or a trace, between both references: from the suppliers’ to the buyers’ identification.
So, it must be clear that the evidence in the file is about the product that is in the file.
Photographs can be helpful, but it is common to ask the supplier for a ‘Declaration of Product Identity’.
The declaration simply states that the product with the suppliers’ reference in the conformity documentation is identical to the product with the purchasers’ reference.
The Declaration of Product Identity (DoPI) can be a very brief statement about the link between both product reference (see example).
The document is signed by the supplier (because he “owns” the evidence) and added to the technical file.
The product identity declaration can also be used to declare that a series of products are identical and only deviate in aspects that are not relevant for the conformity of these products.
