Survey Information: Temperature: F Specification: CQI-9 Survey Start Date & TIme: 5/15/2018 10:10:00 AM Survey End Date & Time: 5/15/2018 10:40:00 AM Sample Interval: 120s Overshoot: No Overshoot Time (if occurred): Furnace Condition: Empty Survey Structure: Empty Basket Atmosphere Present? No Furnace Chart: Customer Vacuum Pressure (if applicable) N/A Survey Notes: -TUS performed with heat sinks per customer request. -TUS performed using a single basket placed in the center of the workspace, per customer request. All displayed thermocouple values included in this report are CORRECTED. All correction values are identified in this report Heat Treating Services Unlimited,Inc.has been audited and found in compliance with ISO/IEC 17025:2005. Calibrations performed at the customers facility within the labs scope of accreditation are indicated by the presence of the Accrediting Body's logo and Cert# on this certificate of calibration. All results contained within this certification relate only to items calibrated. Any number of factors may cause the calibration item to drift out of calibration before the instruments calibration interval has expired. This report must not be used to claim product certification, approval or endorsement ny L.A.B., NIST, or any goverment agency. The standards used in these calibrations are traceable through the National Institute of Standards and Technology (NIST) or another National Metrology Institute to the International Systems of Units. Complete records of work performed are maintained by HTSU and are available for inspection. The results in this report relate only to the items calibrated or tested. When statements of compliance are made the measurement of uncertainty is not taken into account. The Uncertainty of Measurement is 0 to 1093 C = 1.1 C, 1093 to 1250 C = 2.7 C The reported expanded uncertainty of measurement is stated as the standard uncertainty of measurement multiplied by the coverage factor k = 2, which for normal distribution corresponds to a coverage probablilty of approximately 95%.
