( s (3) The initial CHANNEL CALIBRATION shall be performed using one or more of the reference standards certifiec by the National ~Eureau cf Standards or using standards that have been cbtained f rcm suppliers that participate in reasurement assurance' activities with NES. These standarcs shall permit calicrating the system over its intendec range cf energy and measurement range. For subsequent CHANNEL CALIERATION, sources that have been related to the initial calibration shall be used.
