13.0 Notes:
1. The reported value has been rounded off as per IS: 2-1960 wherever applicable.
2. This Certificate Refer only to the Particular Instrument submitted for the Calibration and Results are Applicable only to the Item (UUC)
mentioned Above which has been Calibrated and do not apply to the other item even though declared Identical.
3. This Certificate shall not be reproduced Except in full, if reproduced in a part or Abstract thereof has to be Specifically approved in
written from the Calibration Laboratory.
4. The results reported in this Certificate are Valid at the time of and under the stated Condition of Measurement.
5. Oorja Technical Services Pvt. Ltd. shall not be liable for any change in Calibration Data and Performance Specification on Account of
Malfunctioning of Item due to any Damage or Mishandling caused to it after the Certificate in Respect of it has been issued.
6. The standard used is traceable to National /International standards.
7. Calibration is performed without doing any adjustment or correction in it’s original condition at the time receipt.
8. The user should determine the suitability of the instrument for it’s intended use
9. This calibration certificate is valid only if the stated weights/ equipment/ UUC is used for scientific/ research and industrial purpose, if
used for commercial trading, additional recognition /approval shall be complied as required by department of legal metrology,
regulatory bodies, etc.
10. The reported expanded uncertainty is at coverage factor k=2 which corresponds to a coverage probability or level of confidence of
approximately 95% for a normal distribution.
11. The Error (UUC. Reading- Reference Standard Instrument Reading) is Positive except when Indicated otherwise; it has to be
Algebraically added to the UUC Reading in Order to get the Standard Reading.
