IEC 61508 functional safety standard indicates Safety Integrity Levels (SIL) needs to be evaluated by three design barriers:
Systematic Capability is achieved when the equipment…
IEC 61508 and IEC 61511 functional safety standards allow Safety Integrity Levels (SIL) to be used four ways by end users:
IEC 61508 Certification is a Third-Party Validation against the standard’s requirements, comprising of:
To achieve an…
Systematic Capability is achieved when the equipment used to implement any safety function achieves two goals: the design process has used procedures intended to prevent systematic design errors (fault avoidance) and the design has systematic design control mechanisms such as a diagnostic for incorrect software execution (fault control). The rigor…
You don’t’ really know what you know until you have to explain it (or teach it) to someone else.
When I’m asked about some of the technical aspects of functional safety, I have to stop and ask myself “What Do I Know About This?” I’m not the kind…
The Safety Integrety Level (SIL) of a product is determined by three things:
Systematic Capability is established by having your quality management system audited per IEC 61508.…
