説明

Recently, objective safety assessments by ISA (Independent Safety Assessor) in agreement with international standards including concepts of SIL, RAMS, etc., are required for guided transportation systems (e.g., railways) intended for overseas expansion from Japan. As an ISA, NTSEL has been carrying out many safety assessments and confirming that the probability of seriously dangerous events is sufficiently low. Application of FMEA and FTA is recommended by IEC 62425, and procedures of FMEA and FTA are described in IEC 60812 and IEC 61025 respectively. Such descriptions about FMEA and FTA in these international standards match with NTSEL's traditional design safety assessment methods, and, therefore, these NTSEL's methods will continue to be adopted. As stated above, a basic structure of standard ISA's design safety assessment reports has been presented. Further, a new activity for the technical assessment method taking reliability into consideration with continuous firm policy of "safety first" is introduced.
