IEC 60880
IEC 60880:2006 (Nuclear Power Plants – Instrumentation and Control Systems Important to Safety – Software Aspects for Computer-Based Systems) is a functional safety standard which, together with IEC 62138, covers the software aspects of computer based systems used in nuclear power plants to perform functions important to safety. IEC 60880 provides requirements for the safety category A as defined by IEC 61226.
Fitness for purpose litigation against companies and individuals is now an increasing risk. IEC 60880:2006 is a technical standard used by lawyers to interpret laws. The relevant law in question for Europe is the General Product Safety Directive 2001/95/EC (GPSD). This states that the product creator has the responsibility to develop a safety critical product in a way which is compliant with ‘State-of-the-Art’ development principles. ‘State-of-the-Art’ simply refers to commonly accepted best practices, which in the case of nuclear electronic safety related systems are now embodied in IEC 60880:2006. Where companies fail to employ accepted industry practices, they cannot use the “State-of-the-Art” legal defence against such litigation.
