Blog Entry: Back to Basics 10 – How Does a Product Get a SIL?
IEC 61508 functional safety standard indicates Safety Integrity Levels (SIL) needs to be evaluated by three design barriers: The Systematic Capability Rating The Architectural Constraints for the Element The Probability of Failure for the Product Systematic Capability is achieved when the equipment used to implement any safety function is designed…
Recorded Webinars: Introducing the Back to Basics Functional Safety Series
This year we have created a new series of webinars and blogs; Back To Basics. In the Back to Basics series, we discuss everything from functional safety general terms and descriptions all the way to topics like advanced component analysis.
Looking back at the start of my career with exida, when I took on this new functional safety role, I remember trying to keep track of all the new terms, definitions and acronyms. This was overwhelming and at times even defeating. After years of experience, I started helping exida academy and became an instructor for the week long FSE 100 class. This is when I saw a true need in our industry. I quickly found that many people were in the same boat I was in when I first started! (Regardless of their years of experience)
This realization was the start of Back to Basics and I hope it becomes your “Go To” for functional safety knowledge. This series will start with an overview of general functional safety terms and then expand into both IEC 61508/OEM specific and IEC 61511/End User specific through terms, definitions, examples, pictures, etc., all explained in ways everyone can understand!
To get the Back to Basics series started let’s start at the very beginning with introducing:
- What is functional safety?
- What are the safety standards? – IEC 61508 and 61511
- What does SIL, SIF, SIS all mean?!
- What is a safety function?

Recorded Webinars: A Common Development Process for IEC 61508 and IEC 62443
A product development process should ensure a good understanding of what is to be developed, how it is to be developed and that it has been developed correctly. IEC 61508 and IEC 62443‑4‑1 both have development process requirements. These requirements overlap and separate efforts when assessing compliance to both standards would mean duplicating efforts to assess the common requirements. By identifying what process requirements are in common between IEC 61508 and IEC 62443‑4‑1 and showing that the IEC 61508 process requirements meet the IEC 62443‑4‑1 process requirements, the cost of developing procedures, and assessing procedures for compliance with both standards, can be reduced.
Blog Entry: Back to Basics 09 – Safety Lifecycle – IEC 61511
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 an example. The lifecycle is set up like this: Analyze the situation and document the safety…
Blog Entry: Duty of Care (Too Good to Be True Failure Rate Data)
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 usually doing a SIL verification calculation for an operating plant or for an EPC working closely…
Recorded Webinars: How Using Templates Can Lead to Improved Functional Safety Management Plans
Functional safety management is critical for managing and mitigating systematic failures that can occur throughout the safety lifecycle. Implementing a robust functional safety management plan following the requirements of IEC 61511 can improve the consistency of functional safety lifecycle steps and help to ensure the accuracy of the work performed. This webinar will cover the importance of functional safety management, how to use templates as a starting point for a functional safety management plan, and the benefits of implementing a robust functional safety management plan.
Blog Entry: Back to Basics 08 – IEC 61511
IEC 61511: 2016 Process Industry Sector IEC 61511 is a technical standard that sets out practices in the engineering of systems that ensure the safety of an industrial process through the use of instrumentation. It entails requirements for users of process control and instrumentation for component / element or sub-system…
Blog Entry: Back to Basics 07– Safety Lifecycle – IEC 61508
The IEC 61508 standard recommends the use of a functional safety lifecycle. Any safety lifecycle can be used, but the standard does lay out a nominal 16-step process which can be divided into three main classifications as an example. The Analysis phase of the lifecycle deals with gathering background information…
