本标准的目的是提供以下信息: (a) 风险的基本概念以及风险与安全完整性的关系(见条款 A.4); (b) 可容忍风险的确定(见附件K); (c) 能够确定安全仪表功能(SIF)的安全完整性等级(SIL)的多种不同方法(见附件 B 至 K); (d) 多个安全系统对确定实现预期风险降低能力的计算的影响(见附件 J)。
Although IEC 61511 uses a lifecycle concept, it is no mirror image of ISA 84.01-1996. An international standard must harmonize the standards of many countries. Consequently, the standard will add new requirements for management of functional safety, component selection, design, pre-startup ...
determination or use evidence provided by the vendor or third party certification body FAULT TOLERANCE In ISA 84 01 1996 the design was considered adequate as long as the PFDavg was achieved by the SIS design In addition to the PFDavg IEC 61511 requires that the SIS demonstrate a minimum ...
required that the SIL be verified. After commissioning the SIS, a pre-startup acceptance test was required that included input to output testing to ensure that the SIS works in the actual installation as intended by the design. These same activities occur in IEC 61511, but this standard ma...
