[SystemSafety] MISRA publishes Guidelines for Automotive Safety Arguments

[David Ward]

I believe what we had in mind here is that ISO 26262 requires you to demonstrate that a product is "free from unreasonable risks" (despite the wording, this is intended to be equivalent to the notion of "broadly acceptable risk"; there is no recognition in ISO 26262 of ALARP or similar principles although similar principles are being considered as part of the SOTIF - safety of the intended functionality - approach).

I'm not a qualified lawyer but my reading of the criminal law law (specifically HSWA 1974) is that it requires that the risk must be reduced "so far as is reasonably practical" (SFAIRP) rather than just to industry norms. There will be different duty holders who have that duty depending on whether the vehicle is supplied for use at work, for example. If MISRA is an employer and publishes guidance as part of its work activities, then MISRA may have a duty under the act to reduce the risks from its guidance SFAIRP too. It may be worth taking legal advice.

Hello everyone

I hope it is OK to draw attention to a new publication just released by MISRA, "Guidelines for Automotive Safety Arguments".

The guidelines provide clarity on how to develop Safety Arguments in line with existing standards such as ISO 26262, with a view to justifying that the risk associated with an automotive system is within industry norms. Types of evidence to support the argument are also suggested, as well as advice on practical application.

One of the specific motivations for developing these guidelines was to support the requirements for a safety case in ISO 26262. Since ISO 26262:2018 (ISO 26262 Edition 2) the safety case is now explicitly required to be based on an argument.

The document is now available to purchase from the MISRA webstore.  We also have a dedicated area in the MISRA Bulletin Board for discussing specific questions on this document.
