Stainless Steel Scale Calibration

All monitoring and measuring devices, which affect product quality or utilized by Production and Quality Control for product acceptance, are subject to the Scale Calibration outlined in this policy. Calibration is to make against nationally or internationally recognized standards. Auto Knitwear uses services of Bangladesh Standards and Testing Institution (BSTI) and other renowned sources in the world where required.

PROCEDURE DESCRIPTION:

  • All monitoring and measuring devices are re-validate any product determined to have been inspected or processed by out of calibration equipment. Calibrated Standard SS Scales are kept by Responsible person.
  • System is maintained to identify, assess, and re-validate any product determined to have been inspected or processed by out of calibration equipment. Quarterly, check the accuracy of the used measuring scales on production floor, Laboratory and Inspection area.
  • All calibration, measurement and tests are carried out under suitable environmental conditions and all equipment is maintained and handled to ensure its accuracy and fitness for use. The SS scale kept beside the Calibrated Standard scale and start reading from “Zero” to finish point of the scale.
  • Calibration and/or adjustment of all measuring, control, and test equipment are to be performed by authorized personnel only.
  • Need to Record reading every 20 mm interval on the Verification form.
  • Standard Reading from zero mark (mm) and Unit under Calibration (UUC) from zero mark (mm) is checked parallel every 20cm interval and keep record both scale up to scale reading finish point
  • If Unit Under Calibration (UUC) from zero mark (mm) reading is more or less than Standard Reading from zero mark (mm) then its called Deviation.
  • If Unit Under Metal Detector Calibration (UUC) from zero mark (mm) reading is more than Standard Reading from zero mark (mm) then it will be (-) Deviation and  if Unit Under Calibration (UUC) from zero mark (mm) reading is less than Standard Reading from zero mark (mm) then it will be (+) Deviation.
  • If the measurement is within the tolerance level (± 0.05 mm maximum), than the SS Scale is pass or fit for use.
  • If the measurement is out of tolerance level (more than ± 0.05 mm), than the SS Scale is not pass or unfit for use.
  • If the Measuring scale reading erased or not seen on the scale then corrective action must be taken.
  • If the scale reads within the limits specified in step 8, then the scale passes and is fit for use.
  • If the scale does not pass or unfit for use, make whatever corrective action is required (if necessary, it refer to the supplier).  Record the corrective action on the Quarterly Scales Verification Check Form.
  • After verification, We are using a tag on every ss scale consist of Serial number, date of verification, date of validation, Inspector sign and this tag will change quarterly.

Details of Unit Under Calibration (UUC):

When it is impractical to apply a calibration label directly to an Monitoring and Measurement Device, the calibration label may be affixed to the equipment container or some other suitable measure may be used to reflect calibration status. Any alternate methods shall include the identification number.
