| Abstract: |
| Safety Integrity Level(SIL) assessment basis,function,method and application cases are introduced in this paper.According to the different needs of newly built and constructed projects,different purposes and functions of SIL assessment are described.Then,necessity of SIL assessment is put forward combining with the engineering practice,and the rationality and effectiveness of constructing SIS are expounded referencing to related standards.The next,the basic application method of SIL assessment is discussed with practical engineering cases.At last,the application trend of SIL evaluation is expounded. |
