Safety Integrity Level (SIL) Allocation on Monorail Rolling Stock
2021 Joint Rail Conference, 2021Abstract Railroad and transit projects are increasingly referencing and requiring compliance with the CENELEC railway standards, and the Independent Safety Assessment (ISA) is a key element of the safety certification and homologation process. The Quantitative Risk Analysis (QRA) which includes the Safety Integrity Level (SIL) allocation

Safety instrumented functions and safety integrity levels (SIL)
ISA Transactions, 1998This paper discusses two performance-based standards, ANSI/ISA S84.01 and IEC d61508, and the requirements they place upon user companies of electrical, electronic and programmable electronic safety related systems (E/E/PE SRS) or Safety Instrumented Systems (SIS).

Cost effective alternative in meeting the required Safety Integrity Level (SIL)
Journal of Loss Prevention in the Process Industries, 2016Abstract Demonstrating process safety has always been one of the paramount concerns of Engineering, Procurement, and Construction (EPC) companies in the industrial sector, especially with the development of stringent standards such as IEC-61508 and IEC-61511.

Combination of safety integrity levels (SILs): A study of IEC61508 merging rules
Journal of Loss Prevention in the Process Industries, 2008The role of a safety system is to provide a safety-related function in order to monitor and maintain the safety of any equipment under its control. The safety analysis of such systems is of prime importance to avoid catastrophic consequences or even the loss of human life.

Abstract A SIL assignment method for the design and rectification of SIS used for preventing failure action and spurious activation is presented in this paper. The method has two stages, including SIL assignment based on experience and SIL assignment based on risk quantitative calculation results.

International Journal of Hydrogen Energy, 2019
Abstract This study investigates the safety integrity levels for an electric propulsion system based on a molten carbonate fuel cell in a liquefied hydrogen tanker. The electric propulsion system necessitates multiple electronic and electric elements; thus, the functional safety of the system should be considered.

Safety Integrity Level (SIL) Verification for SLAC Radiation Safety Systems
2015SIL is a key concept in functional safety standards: it is a performance measure on how reliable is a safety system performing a particular safety function. In the system design stage, SIL verification must be performed to prove that the SIL achieved meets/exceeds the SIL assigned during risk assessment, to comply with standards.
