In the electronics manufacturing industry, "SIR testing" is a sensitive test method for evaluating component failure caused by shorts or current leakage. It is used to rate fluxes, board cleanliness and how these wee metal bits perform in humidity. Well fine sir, you may not need your tie to do all that, but this is what the image did on your tie in its former life!
