Product certification or product qualification is the process of certifying that a certain product has passed performance tests and quality assurance tests, and meets qualification criteria stipulated in contracts, regulations, or specifications. C.R. Technology Systems achieved several product certification and tests products at CESI (Centro Elettrotecnico Sperimentale Italiano). The CESI Type Test is an international certification regulated by the IEC/EN 62271-200 reg. within the Safety Act (Legislative Decree 81/2008) on Medium Voltage Switchgears, that assesses the class and the risk-free rate of electrical engineering products. Tests and Certificates by CESI are internationally recognized by utilities and electromechanical manufacturers worldwide, thanks to long time experience and membership of the STL (Short-Circuit Testing Liason).
