[SystemSafety] "Serious risks" in EC 765/2008

[Thierry.Coq at dnv.com]

Hi,

In EC 765/2008, what is considered a "serious risk"? Is there a reference? 
How are the "serious risk" mitigations assessed, especially when "The feasibility of obtaining higher levels of safety or the availability of other products presenting a lesser degree of risk shall not constitute grounds for considering that a product presents a serious risk."?
This standard also mandates that the product should be recalled when the serious risk has materialized... and there is wording here to update the risk assessment with field reports. 
So is a "serious risk" in this standard in fact a materialized danger...?

Thanks for comments.
Best regards,
Thierry Coq

Folks,

<cut> 
I am running a group producing a risk analysis (in the sense of IEC Guide 51) of the charging process for electric road vehicles. There was and is stiff resistance from some quarters. I have pointed out that, first, IEC Guide 51 says that a risk assessment (compromising a risk analysis and risk evaluation) should be required in any safety-related IEC standard. Second that EC 765/2008 on product quality requires (Article 20) that products representing a serious risk be withdrawn from European markets, and that the judgment that products represent a serious risk be made through a risk assessment. This is European law. Since I have pointed that out in sufficiently general meetings, suggestions that the group's work is pointless have all but disappeared (although the will to limit its work has of course not, for this has other bases).
