Abstract

This paper deals with the test facilities and operation of the Field Test and Evaluation Center for Eastern States (EFTC)), operated by the Ohio State University. The principal features of the EFTC fall into three catagories: Facilities involved with water calibration and evaluation, facilities involved with force measurement calibration, and facilities involved with dynamic correlation. Procedures, observations and accomplishments are described in detail. The center operations are currently felt to be accomplishing two functions that are expected to have a primary effect on skid measurement system operations: Standardization of water subsystem delivery rates and distribution; calibration of an air-bearing force plate relatable to the National Bureau of Standards. It is believed that the procedures followed at the center result in significantly improved uniformity of operations among a variety of skid measurement systems and provide a procedure through which skid numbers measured over a wide area may be transformed to reference values.
