INTRODUCTION
1 Scope
2 Normative references
3 Terms and definitions
4 Abbreviations
5 Conditions and strategy to cope with CCF
6 Requirements to overcome faults in the requirements
  specification
7 Design measures to prevent coincidental failure of I&C
  systems
8 Tolerance against postulated latent software faults
9 Requirements to avoid system failure due to maintenance
  during operation
Annex A (informative) - Relation between IEC 60880 and
        this standard
Annex ZA (normative) - Normative references to international
         publications with their corresponding European
         publications

Gives requirements related to the avoidance of CCF of I&C systems that perform category A functions; additionally requires the implementation of independent I&C systems to overcome CCF, while the likelihood of CCF is reduced by strictly applying the overall safety principles of IEC SC 45A (notably IEC 61226, IEC 61513, IEC 60880 and IEC 60709); gives an overview of the complete scope of requirements relevant to CCF.
