In the field of CE certification of products, and its marking, still circulate false interpretations that should be clarified, incorrect beliefs or practices that lasted for years and which, fortunately, are disappearing due to the intensification of market controls.
We refer to a certain tendency in the past between some manufacturers (indulged in the worst cases by consultants) to interpret in a "convenient" the application of standards and guidelines, and to seek "loopholes" for not subjecting the equipment to all the necessary verifications of compliance.
It is not hard to imagine that these producers, acting out of respect for the law, does not have any benefit from these practices; rather, They have witnessed the withdrawal from the market of its products for non-compliance. Besides prove ineffective, these "shortcuts" have led to the failure of these companies and have caused the natural foreclosure.
For the benefit of those working in this area, a little is needed’ of clarity on some “false beliefs” concerning the compliance of electronic equipment, radio and telecommunications terminal equipment with the requirements for CE marking.
There are still ambiguities about: so it is useful to explain the rules and procedures to be followed for a correct approach in the field of product certification.
Take for example the CE marking in accordance with R&TTE an application that uses certified radio modules.
An application that integrates a radio module itself becomes a radio product, regardless of the fact that the module is integrated in the product or purchased separately as an optional.
In both cases, the finished product is subject to full at the R&TTE and is the responsibility of the person placing it on the market to ensure that it complies with the requirements for CE marking.
The product does not comply with directives, as all its members have the certification CE, the product requires a certification as a whole.
Several components may interact and produce unwanted effects.
Actually, who applies a module already certified can be assumed that it conforms to some of the technical requirements and has the advantage of having to perform only a small part of radio tests, could refer to those already made by those who produced the components. In these cases it is important to verify that the certification CE for each component is present, namely, that does not refer to outdated versions of the standard, otherwise it will be necessary to repeat the radio tests complete.
As for the aspects that are under the direct control of the designer, as for example the use of frequencies permitted in the area of use for the wi-fi modules, We must perform the appropriate tests on the final product and verify that complies with all the parameters. testing should also be performed relating to electromagnetic compatibility and those on product safety, in accordance with the guidelines provided by the R&TTE.
At someone's eyes, the correct approach may appear laborious, in addition to being expensive. Even if we were to limit ourselves to consider only the economic aspect, operate in compliance with the rules is more beneficial than imagined, especially when compared to the financial risk arising from the withdrawal of its product from the market.
