Safety Integrity Level (SIL) Classification

sil9a

5 Classes of demand ( D)

D0: negligible demand rate; the scenario has not been heard of in industry;

D1: the interval between demands is more than 20 years; the scenario is unlikely to occur during the lifetime of the platform, but has been heard of in industry;

D2: the interval between demands is 4 to 20 years; the scenario is likely to occur during the lifetime of the platform or has already occurred before in the platform;

D3: the interval between demands is 6 months to 4 years; the scenario is likely to occur in the time period between two major stops;

D4: the interval between demands is less than 6 months; the scenario occurs several times per year on the platform
