摘　　要：自从功能安全国际标准IEC61508及IEC61511制定以来,安全仪表系统已经在国内外得到了广泛的应用。但在安全仪表系统的应用过程中仍然存在一些具体问题。随着国际标准的不断更新,同时也进行了相应的修改。本文通过对比各种功能安全标准所规定的内容,对标准中出现的异同进行分析,并对今后的功能安全标准修改进行了简单的探索。Since the international functional safety standards IEC61508 and IEC61511 have been formulated, safety instrumented system has been widely used at home and abroad. However, there are still some speciifc issues in the application of safety instrumented systems. With constantly updated international standards, but also for the corresponding modiifcations. This article compares the various functions which were required safety standards for the contents of the similarities and differences, and analysis that appear in the standard analysis, and to modify future functional safety standard for a simple exploration.
