I have been asked this question many times by various clients over the years. This comes down to whether a perfect proof test is assumed or not. Let us remember that Mission Time is defined as the amount of time we expect a set of SIF equipment to run until a major overhaul is required, usually based upon the useful life of the devices. This time is set by the end user. Some companies are still not appreciating how greatly they will overstate the risk reduction of the Safety Instrumented Function (SIF) by assuming perfect proof testing since Mission Time then has no impact.
Therefore, what is perfect proof testing and what does this mean? We will discuss this among other things in this webinar.
