Barometer: N/A This certificate documents traceability to the National Institute of Standards and Technology (NIST) and the International Syst(em of Units (SI). The Laboratory quality system conforms to ISO/IEC 17025,2005, ANSVNCSL 2540-1-1994 and relevant requirements of the IS0 9000-2000 :standard. This certificate shall not be reproduced, except in full, without the written approval of the Southwest Research Institute Calibration Laboratory. This certificate shall not be used to cliiim product endorsement by Southwest Research Institute, American Association for Laboratory Accreditation (AZLA) or any agency of the U. S. Government. Results of this calibration relate only to the instrument described above at the time of calibration and does not imply any long term stability of the instrument.

*Determined by the customer, does not imply the instrument will remain within tolerance as any number offactors may cause .an out-of-tolerance condition before this date. **Data type found in this certificate or attached measurement report must be interpreted as: Found-left - adjustment and/or repair was not performed, As-found - data is before unit is adjusted and/or repaired, As-left - data IS after adjusted and/or repaired was performed. The customer has sole responsibility for determination of in-/out-of-tolerance or compliaricdnoncompliance.

Meaiiurement uncertainty calculated in accordance with the method described in the IS0 "Guide to the Expression of Uncertainty in Measurement" (GUM), for a confidence level of approximately 95 percent using a coverage factor of k =2.

Remarks: ASME Grade B Tolerance (2% Middle Half, 3% First and Last Quarter of Dial) Referenced to 0°C.
