Weighing should be performed using a balance that is calibrated over the operating range and meets the requirements defined for repeatability and accuracy. A balance weight makes a reliable check-weight. The measurement shall be within the 0.1% of the actual mass value of the individual weight as given in the performance check log. Verification of balance is necessary after power failure and movement of balance from one to another place. Switch ON the balance. A collection of tools relating to the USP General Chapters 41 and 1251 and the extensive updates made to these chapters in 2013. Software for Laboratory Weighing. Calibrating a balance closer to the user's actual maximum weighing capacity will offer a more accurate calibration. The 10 mg weight shall meet the performance check criteria of the mass value i.e. The new USP regulations require that balances used for weighing must be calibrated. Mass Comparators SOP for coding and calibration of standard weights. The USP drug standards are used in more than 140 countries, and are enforceable in the US by the Food and Drug Administration (FDA). Deviation NMT +05% of the actual mass value. Microbalances— Proceed as directed for Analytical Balances, but use a check-weight appropriate for the particular balance. 5.7 Perform internal calibration and in Annexure-II 5.6 For Accuracy 5.6.1 Place 5 gm. Each manufacturer supplies the maximum loading condition of the balance. Before you can start the calibration of the weighing instrument, you … Check the accuracy of the balance by using 5 standard stamped weights. If necessary, turn on the power, and allow the balance to Perform the following procedures to reduce balance errors Before calibration make sure that the level bubble is in the center of the indicator and if internal calibration facility is available in the balance then it shall also be performed daily before performance check of the balance. Learn how the advice given can ensure consistently high quality results. The observed balance reading should be within +/- 0.1% of market value of standard weight as per USP 41 requirements. Place standard weight one by one in the increasing order in the center of the platform and record the observations in the balance calibration record. hello sir, verification of balance is necessary after every power failuar.Reply plz. The, Chapter 1251 revisions focus on balance qualification and operation, including the importance of ".
