An evaluation of the diagnostic coverage to produce a rationale for:

1) the compliance with the single-point fault and latent-fault metrics defined in Clause 8;

2) the compliance with the evaluation of the safety goal violations due to random hardware failures as defined in Clause 9.

診斷覆蓋率評(píng)估用來(lái)使用在FMEDA和FTA中。

A guideline in order to choose appropriate safety mechanisms to be implemented in the E/E architecture to detect failures of elements.

診斷覆蓋率評(píng)估有助于選擇合適的安全機(jī)制。

該附錄中給出了一個(gè)實(shí)例，用來(lái)對(duì)常規(guī)的電子電氣系統(tǒng)中常規(guī)元器件的常規(guī)失效模式的診斷覆蓋率，分為60%(低)、90%(中)和99%(高)。
