INTRODUCTION
1 Scope
2 Normative references
3 Terms and definitions
4 Abbreviations
5 Conditions and strategy to cope with CCF
  5.1 General
  5.2 Characteristics of CCF
  5.3 Principal mechanisms for CCF of digital I&C systems
  5.4 Conditions to defend against CCF of individual
      I&C systems
  5.5 Design strategy to overcome CCF
6 Requirements to overcome faults in the requirements
  specification
  6.1 Deriving the requirements specification for the
      I&C from the plant safety design base
  6.2 Application of the defence-in-depth principle
      and functional diversity
  6.3 CCF related issues at existing plants
7 Design measures to prevent coincidental failure of
  I&C systems
  7.1 The principle of independence
  7.2 Design of independent I&C systems
  7.3 Application of functional diversity
  7.4 Avoidance of failure propagation via
      communications paths
  7.5 Design measures against system failure due to
      maintenance activities
  7.6 Integrity of I&C system hardware
  7.7 Precaution against dependencies from external dates or
      messages
  7.8 Assurance of physical separation and environmental
      robustness
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

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.
