B-7646 yellow samples were thermal transfer printed with a BradyPrinterTM PR300 PLUS using Brady Series R-6600 ribbon and shrunk on appropriate size wires. Test was conducted at room temperature after 24 hour dwell. Testing consisted of 5 cycles of 10 minute immersions in the specified chemical reagent followed by 30 minute recovery periods. After final immersion, samples rubbed 10 times with cotton swab saturated with test fluid.
