Regarding instrument safety certification issues
Thread Content
The latest process specifications provide a risk level analysis, indicating that the instrument safety level is SIL1. Now the question is: do I still need to indicate on my list of safety instrumented systems that the instrument safety level is SIL1? I haven’t come across any instruments with a SIL1 rating in the market
Instrumentation devices with SIL1 rating have not been seen on the market, because once they undergo SIL certification, their rating becomes SIL2 or higher. No labeling is required; it is indicated on the standard nameplate that has undergone SIL certification
Thank you{:1_90:}
