Independent factory inspectors

Each company that applies for oSa-membership will have to undergo a factory inspection carried out by an independent auditor. Apart from the inspection of the production facilities, the test and appraisal methods will be audited as well as the capability of the manufacturer to continously meet the highest safety standards.
