SIL Safety Manual OXYMAT 6 Gas Analyzers 8 of 19 A5E. 2 Safety Integrity Level ( SIL) Definition: SIL The international standard IEC 61508 defines four discrete Safety Integrity Levels ( SIL) from SIL 1 to SIL 4. Each level corresponds to the probability range for the failure in a safety function. SIL ( Safety Integrity Level) The safety integrity level ( SIL) is a benchmark for the safety integrity of a system. The safety integrity is the probability that the system will perform the required safety- related function under all defined conditions within a specified period of time.

    Trusted By 200+ Million Users Worldwide. Send & Sign - Anywhere and Any Device. as the SIL level increases, the cost and complexity of the hardware/ system also increase. The four SIL levels are defined, with SIL 4 being the most dependable and SIL 1 being the least. A SIL is determined based on a number of quantitative factors in combination with qualitative factors such as development process and safety life cycle management. levels are called safety integrity levels, or SIL. Determining the required SIL The higher the numerical value of the safety integrity level ( SIL), the greater the reduction in risk. This means the SIL is the dimension for the probability that the safety system can correctly fulfill the required safety functions for a spe- cific time frame. What is functional safety and what is SIL? IEC 61508 and IEC 61511 The international standard IEC 61508 defines SIL using requirements grouped into two broad categories: hardware safety integrity and systematic safety integrity. A device or system must meet the requirements for both categories to achieve a given SIL. Functional safety” has come into focus since the publi- cation of the IEC/ EN 61508 and IEC/ EN 61511 standards.

    The term SIL ( safety integrity level) is used frequently in this context. What is the SIL level of a system? What are the two types of SIL requirements? Safety Integrity Level ( SIL/ 61511. Background: SIL Determination. Safety Integrity Level ( SIL) is defined as a relative level of risk- reduction provided by a safety function, or to specify a target level of risk reduction.
