[QUOTE] The manufacturer's product technical file will outline which models are covered by the application for EC Type-Examination. They will instruct the test house and Notified Body (which may be seperate organisations or one and the same) how they envisage the products fall within a family and how this corresponds with any design or performance requirements stipulated in the standard. New models can be added to the existing certification at future dates, but only if the manufacturer understands what processes and documentation they need to put in place at the front end to provide this level of commercial flexibility.[/QUOTE] So, manufacturer says "these are all pretty much the same, so we only need one certificate for the lot". Testers agree or disagree. But what does that mean in practical terms? What sort of things would be sufficient that a new model couldn't be added to an existing certificate? [QUOTE] Few manufacturers fully comprehend how to achieve this, however, which is why their costs can be higher than they need to be. I have worked with companies who have spent three times what they needed to on testing, had they retained me instead, and are still no closer to obtaining product approval than they were at the outset. To me, any motorcycle clothing manufacturer who bleats about the high cost of CE marking their products as a reason for not doing so, reveals that they don't have a clue how to run an EC Type-Examination project and how to achieve best value - particularly when there are business grants available to offset up to 50% of the costs![/QUOTE] If the rules are too complicated, or too badly communicated to the manufacturers for them to understand/take advantage of, then the whole process is failing and the tests are of less value. Not the test itself, perhaps, but why would I bother to seek out certificated products if I might reasonably believe that a lot of uncertificated gear is actually of just as good a standard?
