    SOP on Calibration of Weighing Balance :


    1. Purpose: To lay down the procedure for the calibration of weighing balances.
    2. Scope: Applicable to all weighing balances except analytical balances.
    3. Responsibility: Department Head.
    4. Definitions: Calibration: The set of the operations which establish under specified conditions , the relationship.
    5. Procedure.
    6. Preparations before calibration. Before you can start the calibration of the weighing instrument, you .
    7. Eccentricity test. In normal use of a weighing instrument, the load is not always placed perfectly on .
    8. Repeatability test. As any instrument, also weighing instruments may suffer from repeatability .
    9. Weighing test. The purpose of the weighing test is to test the accuracy (calibrate) of the weighing .

    11. The check should be made before the first weighing of the day or after any event that might disturb the balance's calibration (power failure, moving the balance to a new location, etc.). The check-weight may be any object whose mass remains constant and does not exceed the load limit of the balance. A balance weight makes a reliable check-weight. Each balance should be provided with a check-weight, which.

      Deht and Ceht in Pharma Industry: Dirty Equipment Hold Time   (DEHT): Elapsed time between the end of a manufacturing / packaging process аnd execution of the complete cleaning procedure. Clean Equipment Hold Time (CEHT): Elapsed time between the end of a complete cleaning process and introduction of product for the next use. A: The rational to CHT is described in the answer to Q2 and Q2a. The question on how many days you should take into consideration is predominantly depending on your internal processes. The maximum expected clean hold time should be used for the study. To give a simple example: consider you make a cleaning of an object on Friday and have no manufacturing at the weekend. Probably the next Monday is a public holiday and so the maximum clean hold time after cleaning is 4 days (depending on when you start manufacturing using the cleaned equipment).
