Functional safety is a fundamental part of system and equipment engineering. 
Many standards have been developed to provide concepts and methods that can be used by safety engineers. For them, the safety analisys of any application always starts from the evaluation of risk and the "target" performance which shall be fulfillled by the safety system to be designed. Safety standars usually provides simplified methods to analize hazards and risks, usually in the form of graphs or tables.

This app considers the three fundamental functional safety standards and it implements the risk graph described by each of them. 
- IEC 61508: it is the core standard for functional safety. Many other standards derives from it. The output of the risk analisys is the SIL value (Safety Integrity Level)
- EN ISO 13849-1: this standard has been developed for machinery, and it is widely used in this type of application. The output of the risk analisys is the PL value (Performance Level). 
- ISO 26262: common automotive safety standard. The output of the risk analisys is the ASIL value (Automotive SIL).
功能安全是系统和设备工程的基础部分。
已经开发了许多标准来提供安全工程师可以使用的概念和方法。对于他们来说，任何应用的安全分析总是从风险评估和“目标”性能开始，这些性能应由要设计的安全系统来实现。安全标准通常提供简化的方法来分析危害和风险，通常以图表或表格的形式。

该应用程序考虑了三个基本功能安全标准，并实现了每个标准所描述的风险图。
- IEC 61508：它是功能安全的核心标准。许多其他标准源自它。风险分析的输出是SIL值（安全完整性等级）
- EN ISO 13849-1：该标准是为机械开发的，它广泛用于此类应用。风险分析的输出是PL值（性能等级）。
- ISO 26262：通用汽车安全标准。风险分析的输出是ASIL值（汽车SIL）。
