Answer / abdulkalim
Definitions:
------------
Calibration: This is an act of checking or adjusting by
comparing with known standard for accuacy of the instrument
to meet the defined criteria with a specificed degree of
confidence.
Performance Verification:
-------------------------
It is an activity to document that the instrument
consistently performs accordingly to the predefined
specifications which is appropriate for intended use.
Differences:
------------
Calibration is the process where we can do adjustment is a
part of calibration but not necessary.
Where as Peformance Verification is only the act to check
the Performance of the instrument.
Example
-------
Using Salicylic acid and Prednisone Tablets for Dissolution
Apparatus (Chemical testing) is a Performance Verification
test rather being called as "Calibration" since we are
checking the performance of the equipment whereas we are
not doining any adjustment at any point of time .Hence it
is eventually called as "Performance Verification"

Answer / prasad
calibration is to check that perticular instrument is
working under specified limits and conditions

Answer / gayathri
Calibration is confirming periodically whether the
instrument is working properly with respect to the
particular parameters and ensuring that the same can be
used in the future.

Answer / alpesh patel
Calibration is to verify the particular instrument with the
comparition of known standard or instrument.

Answer / deepakm
calibration is the set of operations under specified
conditions that establishes a relationship between the
values of quantities indicated by the measuring instrument
or system and the corresponding values indicate by the
standard and to adjust if any deviations are observed to
bring into tolerance limitsi.e. this is basically the
comparision of process against a standard.
verification means to verify something against some set of
standards to find out whether it meets the requirements or
not.it is only an act of checking bt no adjustment has to be
done.

Answer / pankaj pawar
Calibration is simply the process of comparing the unknown with a reference standard and reporting the results. For example:
Applied= 1.30V, Indicated= 1.26V (or Error= -0.04V)
Calibration may include adjustment to correct any deviation from the value of the standard.
Verification, as it relates to calibration, is the comparison of the results against a specification, usually the manufacturer's published performance figures for the product. (e.g. Error= -0.04V, Spec= ±0.03V, "FAIL"). Some cal labs include a spec status statement on their Certificate of Calibration. (i.e. the item did/did not comply with a particular spec).

Answer / basha
calibraion is the checking the instrument with reference
standards they are in limit or out of limit
| Is This Answer Correct ? | 5 Yes | 2 No |
Answer / balakrishna
Calibration: it is a process where an instrument is set to
provide a correct response to a given set of conditions.
verification:it is a process for such instruments is one of
challenging the performance of the instruments by measuring
known standards.
