Common use of Equipment Calibrations Clause in Contracts

Equipment Calibrations. Prior to the start of the test program, Purchaser will receive copies of all sampling equipment calibrations and test CEMS calibration gas standards as described in their stack testing guidelines. New items for which calibration is required are calibrated before initial field use. Equipment whose calibration status may change with use or time shall be inspected in the field before testing begins and again upon return from each field use. When an item of equipment is found to be out of calibration, it will be repaired and recalibrated or retired from service. All equipment shall have been periodically recalibrated in full, regardless of the outcome of these regular inspections. Calibrations shall be conducted in a manner and at a frequency which meets or exceeds EPA specifications. The Independent Testing Company shall follow the calibration procedures outlined in the EPA Methods, and those recommended within the Quality Assurance Handbook for Air Pollution Measurement Systems: Volume III (EPA-600/R94-038c). When these methods are inapplicable, the Independent Testing Company shall use methods such as those prescribed by the ASTM. Data obtained during calibrations will be recorded on standardized forms, which are checked for completeness and accuracy by the Independent Testing Company. Data reduction and subsequent calculations shall be performed using the Independent Testing Company’s computer facilities. Calculations shall be checked no less than twice for accuracy. Copies of calibration forms are included in the test report. Emissions sampling equipment requiring calibration includes, without limitation, sampling nozzles, pitot tubes, pressure gauges, thermometers, dry gas meters, and barometers.
