2、ty Management nIEC 61508 part 4- 3.1.9 define nfunctional safety npart of the overall safety relating to the EUC and the EUC control system which depends on the correct functioning of the E/E/PE safety-related systems, other technology safety-related systems and external risk reduction facilities nM

3、ore practical terms nFunctional Safety Management governs equipment and process safety activities involving safety systems. nThe purpose is to reduce the possibility of a SYSTEMATIC FAULT. 功能安全管理FS4 nIEC 61511 nDefines 61508 application in Process Sector nDefines the Application of Safety Instrument

4、ed Systems for the Process Industry IEC 61511 - Standard Life Cycle 功能安全管理FS5 FSM - Objectives nSpecify management and technical activities during the Safety Lifecycle to achieve and maintain Functional safety nSpecify responsibility of persons and organizations nExtend an existing and monitored qua

5、lity system nPlan nExecute nMeasure nImprove 功能安全管理FS6 IEC 61508 / 11 version of FSM nFSM focuses of procedures, the standard provide a good reference n61508 cover everything including safety system hardware and software development nPart 1- Clause 6, lays out details for FSM nBroad coverage can mak

6、e application challenging n61511 focuses on the process owners and safety system users nPart 1, Clause 5 lays out details of FSM nNarrower coverage mange application more manageable 功能安全管理FS7 FSM Key Issues nFunctional Safety Management nSafety Planning- create a FSM plan nRoles and responsibilities
