SIL-kompatibilitet kräver att utformningen av en säkerhetsfunktion uppfyller tre specifika kriterier enligt standarden. Detta avsnitt fokuserar på nummer 1 – Random Hardware Integrity (slumpmässig hårdvaruintegritet).

Safety Requirements Specification. The Safety Requirements Specification (SRS) is a core document, which is used as the main reference to be followed by designers, installers, and operators of a Safety Instrumented Function (SIF). The SRS details all the crucial functional and integrity requirements for …

The extensive level of SRS detail will lift the quality of your SIL loop design significantly. For example, the provided process safety time calculations can help you determine the Logic Solvers execution time or the final element close time.

Valve Repair Shop. INTRODUCTION . The United States Department of Energy's Savannah River Site (SRS) in Aiken, South Carolina is dedicated to promoting SIL Review Safety Requirements Specifications (SRS), Test Plan Development and Optimization, Functional Safety Assessment, HAZOP, LOPA, Safety Instrumented Systems (SIS) Process, Hazard Analysis PHA. lated system (SRS) also increase. The standards IEC 61508 and IEC 61511 therefore define four different safety levels which describe the measures for handling the risks of these components. These four safety levels are the safety integrity level (SIL) defined by the standards.

SRS skal fastsette nødvendig testhyppighet, i tillegg må kravene i SRS også være forenlige med SIL to control process risk to a tolerable level. The SIL is used as a performance measure (in terms of the probability of the SIF failing to perform its required function on demand). Four discrete integrity levels are defined in S84 / IEC 61511 (SIL 1, SIL 2, SIL 3, SIL 4).

SRS-rapporten fastställer säkerhetskraven på instrumentfunktionen. Hur kraven sedan uppfylls framgår av anläggningsdokumentation, såsom SIL-verifieringsrapporter, kretsscheman och instrumentspecifikationer.

It is very common for there to be updates of the SRS following SIL verification. SRS: Safety requirements specification: MTTR: Mean time to repair: SIL: Safety integrity level: PFDavg: Average probability of failure on demand: SIF: Safety instrumented function, same as IPF: STR: Spurious trip rate Safety Integrity Level ( SIL) Each SRS is assigned a SIL o It is the probability that the SRS fulfils its safety function(s ) o Represents objectively the reliability of its safety function(s ) o Product requirement The SIL is assigned according to the required risk reduction o from EUC risk at least to the tolerable risk The extensive level of SRS detail will lift the quality of your SIL loop design significantly.
