C. Sollima, INFN-Pisa VLVnT11, Erlangen, 13 October '11 Quality Control and Qualification Process SOME DEFINITIONS 1) Quality Assurance is a set of preventive activities, which are focused on processes whereas 2) “Quality Control encompasses the operational techniques and activities that are used to fulfill requirements for quality” (ISO 9001) 3) Quality Control is a detection activity, which is focused on detecting the defects once the product is manufactured

C. Sollima, INFN-Pisa VLVnT11, Erlangen, 13 October '11 Quality Control and Qualification Process KM3NeT quality assurance and dependability analysis 1) showed the need for qualification and optimization processes. 2) To allocate reliability to various components (e.g. using accelerated testing) in order to examine (and guarantee) the performance of the required function by the overall system

C. Sollima, INFN-Pisa VLVnT11, Erlangen, 13 October '11 Conclusions  The use of QA standard as ISO 9001’s can help in the quality management system of a VLVnT  The QC for a VLVnT is a complex process that implies an iterative activity between designers and specialists  A DB for QC is very useful in the implementation of a QMS as well a QC.
