摘　　要：介绍IEC标准和国家标准对安全仪表系统设计各阶段的要求,详述历年来原国家安全总局对石化装置安全仪表系统的要求以及我国安全仪表系统的研究和应用现状。提出在过程危险分析与风险评估深度不够和安全完整性等级定级、评估、认证条件不太成熟的前提下,依据安监总局要求和石化企业最常见设备成熟的安全仪表功能,设计现役装置安全仪表系统的方法。The stipulations on various stages of SIS design in IEC codes and national standards concerned were introduced, including the requirements of the former State Administration of National Security for SIS in petrochemical plants and SIS’s application and research status at home. Through considering the insufficient process risk analysis and assessment and SIL rating and the State General Administration of Work Safety’s requirements, as well as the SIF of widely-used devices in petrochemical enterprises, the method of designing SIS die in-service devices was proposed.
