5.1 Equipment Calibration
Chapter 5
Quality Assurance/Quality Control
All project instrumentation is calibrated annually or verified as part of standard operating
procedures. Certificates of calibration are kept on file. Maintenance records are kept for any
equipment adjustments or repairs in bound project notebooks that include the data and
description of maintenance performed. Instrument calibration procedures and frequency are
listed in Table 5-1 and further described in the text.
