ABSTRACT
Quality assurance contracts as organizatorial regulations between industrial manufacturers and their suppliers have been developed to define duties and requirements between all parties involved. Under the headline of quality assurance they contain clauses in nearly all cases which are not at all necessary to support quality but change legal requirements and transform duties to the smaller, weaker part, the supplier.
All commercial contracts and quality contracts too have to obey legal requirements of national law. Most times this is not realized with the consequence that nearly all quality contracts are legally unvalid because they do not follow necessary legal rules.
In cases of damages to be regulated under product liability procedures they proove their unvalidity to a remarcable extent: Over decades they have never been presented to insurance companies or at courts, because the authors felt or feared that the unvalidity might be publicly known by the following decisions.
There are multiple duties between supplier and manufacturer, as diffent as the products involved. Legal requirements always have to be observed carefully, as carefully as technical details even by people without legal training.
