IEC 61508 Certification is a Third-Party Validation against the standard’s requirements, comprising of:
The ISA-18.2 and IEC 62682 standards define an alarm as an “audible and/or visible means of indicating to the operator an equipment malfunction, process deviation, or abnormal condition requiring a timely…
IEC 61508 and IEC 61511 functional safety standards allow Safety Integrity Levels (SIL) to be used four ways by end users:
Last Saturday, I read an article about hackers who were behind at least two potentially fatal intrusions on oil and gas industrial facilities (Yes I read cyber articles on the weekend

IEC 61508 functional safety standard indicates Safety Integrity Levels (SIL) needs to be evaluated by three design barriers:
Information Technology (IT) is the personnel, hardware, and software that controls non-physical devices and/or processes such as websites, financial data, personal information, etc.
Operation Technology (OT) is the personnel, hardware, and software that controls…
The IEC 61511 standard recommends the use of a functional safety lifecycle. Any safety lifecycle can be used, but the standard lays out a process which can be divided into three main classifications as…
I have received several calls lately to our Australia / New Zealand office about whether it is acceptable to use published failure rates that seem too good to be true.
The person calling is…
