All HTPRTs and SPRTs are subject to mechanical shock no matter how carefully you handle them. This shock changes the resistance characteristics of the platinum and shows up as temperature measurement errors. Annealing relieves the stress on the platinum sensor caused by mechanical shock and is recommended by NIST prior to any calibration of an SPRT.

In addition to removing mechanical strain, annealing also removes the oxidation from sensors that have been used for long periods at temperatures between 200°C and 450°C. Oxidation impacts the purity of the element and therefore the accuracy of temperature readings. Oxide is easily removed by annealing at 660°C for one or two hours.
