    A large number of measurements on a nickel-steel alloy bar and on brass inserts in the bar were taken to determine if wear was taking place in the alloy standard or in the Whittemore gage. Microscopic examination was used to confirm the dimensional results. It was concluded that neither the gage nor the brass exhibited significant changes in readings but that the alloy showed a change after 1500 readings. It is proposed that for long-term studies an alloy bar with hardened steel inserts should be used. The precision of measurements made with the gage was estimated from the large set of results.
