result in specified material coefficients being typical mean values

by requiring design features and by requiring a documented process for design and manufacturing

The information in this part of ISO/IEC 27033 is for use when reviewing technical security architecture/design options and when selecting and documenting the preferred technical security architecture/design and related security controls

Industrial communication networks. Profiles - Functional safety fieldbuses. Additional specifications for CPF 18 Ingestion-build-82396 Preliminary investigations1 Scope This part of the IEC 617843 series specifies a safety communication layer (services and protocol) based on CPF 18 of IEC 617842 and IEC 61158 Type 22. It identifies the principles for functional safety communications defined in IEC 617843 that are relevant for this safety communication layer. NOTE 1 It does not cover electrical safety and intrinsic safety aspects. Electrical safety relates to hazards such as electrical shock. Intrinsic safety
