Hi all,
I have just been taking to one of my customers who do control systems for
industrial systems. They have been told by someone they are doing a system
for that SIL ratings will "soon be scrapped". Apparently "It will be
replaced by ALARP". This seems like a completely misunderstood half a
message. Though usually on this sort of thing there is a grain of reality
(if miss reported or miss represented) in there somewhere.
I know I have not been paying attention over the summer but I haven't seen
anything. Is there a move on any standard to change from SIL ratings for
projects?
Regards
Chris
