Prerequisite denied - Appeal Solution

1) So we're going to appeal our failed prerequisit (after finding the limit of 12 seconds on metering faucets). We are planning to upload an invoice for a type of airrator (perlator) product which will reduce the flowrate together with letter of intent signed by the owner that the product will be installed. Do you think this will be enough? Ofcourse the online form will be revised for the new rates. 2) It should be noted that not only is the industry standard, in germany, that flowrates are set at 6 l/min, but it is also required by local quality standard certification programs... the link to the most noteworthy QA program used here is: http://www.well-online.eu/config/media/files/173_WELL%20Klassifizierungsschema.pdf It is interesting that the industry standard in Germany and that of the IPC are so far from each other regarding flowrates (or implied flowrates).
