As the dehydron/disulfide organizational principle is established and shown to hold for soluble proteins, we cannot fail to notice that it also introduces a new set of problems stemming from a basic question What is in physical terms the fate of a soluble protein whose structure significantly violates the architectural constraints defined by the balance equation This issue will be explored in Chap. 5. [Pg.26]

Based on the architectural constraints requirements of lEC 61508 the above system satisfies the requirements for SIL 1 although the PFDavg results are marginal. Note also that both PFDavg calculation and the SFF calculation using the IFC 61508 charts gave the same SIL level. This usually happens when realistic failure rates and proof test parameters are used. [Pg.179]

The architectural constraint fimits are listed in Table 12-8. None of the SIL levels from this table are the fimiting factor as is often the case. Based on the requirements of lEC 61508 the above system satisfies the minimum hardware tolerance for SIL 2. [Pg.184]

The subsystems architectural constraints, SILCL, is determined by use of Table 5 in lEC 62061. The SFF and hardware fault tolerance gives the claimed SIL level in the table, also a use of two parallel (N=l) connected systems/elements gives a one step increase of the single component SILCL level. [Pg.254]

NOTE For the selection of components and subsystems, all the other applicable aspects of this standard still apply, including architectural constraints, hardware integrity, behaviour on detection of a fault and application software. [Pg.61]
