The manufacturer must take all measures necessary to ensure that the products are manufactured in accordance with the technical documentation referred to in point 3 and with the provisions of this Directive that apply to them. I think that means, among other things, that the test results for high-volume production items must be recorded and subjected to the usual quality assurance statistical procedures to control variations before they turn into violations. This is not new: the same applies under the old Directive (which has only 17 days left!), but it is less obviously stated. -- OOO - Own Opinions Only.
