They shall be removed from the conditioning chamber and allowed to return to room temperature. The specimen shall be examined for cracks. The length of exposed conductor, if any, at each end of the specimen shall be considered as shrinkage of the insulation. In no case shall the shrinkage at either end exceed a maximum value of 1/8 in. Following the oven aging, specimens shall be wound tightly around a mandrel approximately but not
