Hi Douglas, A list of Risk Management and Functional Safety Standards you can find in pag.124 of the book “Electrical Product Compliance and Safety Engineering” published at Artech House in 2017. Also an analysis of RM and Methods for Failure Analysis is presented on the same book in Chapters 6 and 5. I hope that above info can help you.

I did an informal search and found that the assessment methods are used in a wide range of disciplines from electrical products to machinery, robotics, safety software controls, medical equipment, medical procedures, automotive, aerospace, traffic control and even tree removal in municipalities. It is very clear that safety professionals worldwide really do like this method and I think it lends a certain comfort to a safety engineer's angst in marginal situations. I probably shouldn't say it but in my personal opinion this is a huge CYA exercise (cover your anatomy) for all involved. Usually the product RA goes before construction review, testing and certification. It is often used to identify areas not covered well by the body of the standard and where additional testing may be required. Virtually all standards describing the use of RA mention the scheme found in FMEA/FMECA of identifying a tasks, operations, or events and assigning numerical values to the parameters of interest, followed by the product of these values to identify level of risk. Commonly these parameters are severity, frequency of exposure, and possibility of avoidance. Today the use of FMEA goes far beyond design, manufacturing, and processes. Often times, a particular standard will say something like "documents that can be used as guidance for the safety analysis include..." followed by a short list of standards from IEC, EN, ISO, ANSI, MIL STD and so on. Notable to me is the use of the word "can" or "may" which implies the user has some leeway in selecting which document they prefer. Additionally, further guidance is often given for "active" protection devices and software/firmware controls for safety function (i.e. safety integrity levels and performance levels). Once again, using the methodology of FMEA as a way of assigning risk levels. So after all that, here is my question. Given wide-ranging product types and use models, the long list of risk assessment standards, has anyone produced a comprehensive list or matrix correlating products to applicable standards? I believe a list such as this would be very helpful.
