This is to attest that PRECISION MEASUREMENT EQUIPMENT, INC. 1584 NORTH BATAVIA STREET, SUITE 1 ORANGE, CALIFORNIA 92867 Calibration Laboratory CL-152 has met the requirements of the IAS Accreditation Criteria for Calibration Laboratories (AC204), has demonstrated compliance with the ISO/IEC Standard 17025:2005, General requirements for the competence of testing and calibration laboratories, and has been accredited commencing December 14, 2015, for the calibration discipline(s) listed in the approved scope of accreditation. The laboratory meets IAS program requirements in the field of calibration. (see laboratory’s scope of accreditation for fields of calibration and accredited calibration methods) This accreditation certificate supersedes any IAS accreditation bearing an earlier effective date. The certificate becomes invalid upon suspension, cancellation or revocation of accreditation. See http://iasonline.org/More/search.html for current accreditation information, or contact IAS at 562-364-8201. C.P.

Calibration and Measurement Capabilities are expressed as uncertainties at approximately the 95% level of confidence, usually using a coverage factor of k=2. The measurement uncertainty of a specific calibration performed by the laboratory may be greater than the least uncertainty due to the behavior of the customer’s device, to the environment (if the calibration is performed in the field), and to influences from the circumstances of the specific calibration.
