Responsibility:Chemist or above of QA shall be responsible to follow the procedure mentioned in this SOP. Analytical Scale Calibration using a set of standard weights. This can be the tolerance of the nominal value of the weight or it can be the uncertainty of measurement for the weight when applying the actual weight value from the certificate. Important note: It is essential that you observe the tolerance limits of the weights used for cal-ibration. 3.0 RESPONSIBILITY: All Department Heads 4.0 ... Balance calibration record : XXXXXXX 9.0 ABBREVIATIONS: 9.1 NMT : Not More Than 9.2 RSD : Relative Standard deviation Email This BlogThis! The key information about USP Chapter 1251 on “Weighing on an Analytical Balance” is that it is only a recommendation – you are not required to follow the procedures described in this chapter. 6.3.10 Before singing the record, authorized person should ensure that calibration is done as per standard procedure and results obtained as well within limit. this sop is applicable to the operation and calibration of analytical balance being used in quality control laboratory. Microbalances— Proceed as directed for Analytical Balances, but use a check-weight appropriate for the particular balance. For example, due to the permissible tolerance limits for a 200-g class E2 calibration weight, the readout may differ from the actual weight by up to ±0.30 mg. USP General Chapter 41 (Balances) sets three distinct requirements to be applied to materials that must be accurately weighed. The scales’ calibration must be validated as per the requirements of a recognized national calibration laboratory. Drift check For the calculation of the drift 10 mg weight shall be used. Ensure appropriate environment. Facebook Twitter LinkedIn WhatsApp. Ensure that Operation & Calibration of the instrument is carried out as per SOP. Air currents can affect the intricate mechanisms of the analytical balance, just as temperature and vibration can alter the measurement of a small sample size. “Calibration and Verification: Two Procedures. The USP Performance test with procedures and acceptance criteria for solid oral dosage forms is ... and use of validated analytical procedures. Even the slightest breeze or vibration can affect the readings. 2. 2. 1.Purpose: To lay down the procedure for the calibration of weighing balances. SOP 8 Modifications. Many of these instruments also have own USP general chapters, for example: •21> Thermometers, 31> Volumetric apparatus, 41> Weights and balances As per USP, balance calibration parameters are Internal adjustments, Linearity, Sensitivity, Repeatability (Uncertainty), and Accuracy, etc. Regards After internal adjustment completed, proceed with daily calibration as per calibration sop prior to routine work. A test weight is suitable if it has a mass between 5% and 100% of the balance’s capacity. Introduction In most facilities, the balance is a critical item of equipment which must operate correctly and have suitable traceability in order to ensure the quality of test results. 2. 5.2. Calibration of Weights and Balances, E Morris and K Fen, Australian Government National Measurement Institute. SOP on Calibration of Weighing Balance. They are recommended for calibration of balances using optical or electrical methods for accurately weighing quantities below 20 mg. Class 1 weights are designated as high-precision standards for calibration. I know many pharma analytical lab are doing balance calibration daily at least with 2 std wts. Note down the 10 … balance performs calibration automatically for greater accuracy. Having Comparable Objectives and Results”; OIML BULLETIN; vol. Head QC or Designee shall be responsible for: Check the SOP. cGMP’s speak to analytical instrumental qualification (AIQ), which includes installation qualification (IQ), operational qualification (OQ) and performance qualification (PQ).

USP General Chapter 1251 "Weighing on an Analytical Balance" is a guideline applicable to balances used in all analytical procedures. Many leading analytical balance manufacturers provide built-in "auto calibration" features in their balances. Scope: Applicable to all weighing balances except analytical balances. Repeat the intermediate weighing of the weight cart as if multiple weights were being verified. The USP requires a simple test – ‘a balance/the test weight’ is sufficiently accurate if the weighed value displayed does not differ by more than 0.10% of the conventional mass of the weight placed on the balance. The United States Pharmacopeia (USP) General Chapters <41> "Balances" and <1251> "Weighing on an Analytical Balance" aim to ensure weighing accuracy and eliminate unnecessary over-testing for US pharmaceutical manufacturers and suppliers.
