Here’s an explainer of what ASIL-D certification entails:...

Oh even more fun: are you by any chance planning to build a chemical plant? Or perhaps a nuclear one?

Well, if you are you’ll probably want your control systems to be as reliable as possible, which is what the SIL standard is about. Apparently Ferrocene is SIL4 certified, which is the highest possible level!

Article Talk
In functional safety a safety instrumented
system (SIS) is an engineered set of
hardware and software controls which
provides a protection layer that shuts down a
chemical, nuclear, electrical, or mechanical
system, or part of it, if a hazardous condition
is detected.!!
Requirement
specification
An SIS performs a safety instrumented
function (SIF). The SIS is credited with a
certain measure of reliability depending on
its safety integrity level (SIL). The required
SIL is determined from a quantitative
process hazard analysis (PHA), such as a

Safety integrity level
Article Talk
XA
In functional safety, safety integrity level
(SIL) is defined as the relative level of risk-
reduction provided by a safety instrumented
function (SIF), i.e. the measurement of the
performance required of the SIF.!1]
In the functional safety standards based on
the IEC 61508 standard, four SIls are
defined, with SIL4 being the most
dependable and SIL1 the least. The
applicable SIL is determined based on a
number of quantitative factors in
combination with qualitative factors, such as
risk assessments and safety lifecycle
management. Other standards, however,
may have different SIL number definitions.[2]
