摘要
从产品的风险和安全完整性的基本概念出发,介绍了电子产品2种工作模式下的目标失效率的同一性、安全完整性级别的选取原则、风险和安全完整性的内在关系。最后用低到适当可行原理(ALARP)解释风险评估的方法,便于读者理解和贯彻ICE62278:2002和IEC62279:2002标准。
Starting from the basic concepts of product risk, safety integration, the identity of target inefficiency, selection principle of safety integration along with the inter-relationship between risk and safety integration are introduced for the electronic products under two working modes, The way by use of ALAPP principle is applied to explain the risk evaluation so as to help understand and implement standard ICE62278：2002 and IEC62279： 2002.
