What is calibration in QA/QC?
Quality assurance calibration empowers customer service with the capabilities to achieve consistency across the entire department. Calibration ensures your QA analysts are all on the same page and that everyone's goals are in line.
Calibration is the process of comparing a reading on one piece of equipment or system, with another piece of equipment that has been calibrated and referenced to a known set of parameters. The equipment used as a reference should itself be directly traceable to equipment that is calibrated according to ISO/IEC 17025.
Calibration in QMS.:
Calibration is an important part of maintaining a QMS that meets ISO 9001 in calibration requirements. It helps to ensure the accuracy and consistency of measurements, which are essential for making decisions about product quality.
Process:
The process of configuring an instrument to provide a result for a sample within an acceptable range. Eliminating or minimizing factors that cause inaccurate measurements is a fundamental aspect of instrumentation design.
Prepare Master List of Inspection, Measuring and Test Equipment
👉 equipment name/identification number
👉 holder of equipment for recall purpose
👉 frequency, criteria of acceptance, range of tolerance date of calibration
👉 work instruction or procedure for calibration, to be in-house or external calibrated recall date.
- Ensure inspection, measuring, and test equipment is calibrated against Certified/Reference Equipment having a known valid relationship to Internationally or Nationality Recognized Standards.
- Ensure Inspection, Measuring, and Test Equipment that is out of calibration is withdrawn from use.
There are only nine types of inspection, and test measurement conducted to verify the performance of installations at commissioning or service. These are:
– dead weight tester
– temperature measurement
– linear measurement
– current rating of equipment
– the resistance of a current carrying loop
– the insulation resistance of a current carrying loop
– electrical voltage measurement
– water flow rates for hydrant systems
– hydraulic pressure for pipe installation
The calibration of any instrument will be considered invalid if any of the following situations occur:
- expiry any period as shown on the label
- excessive electrical overload
- tampering
- excessive mechanical shock
If an equipment is found to be out of calibration, the validity, and critically of previous recorded results must be assessed by the calibration controller, or his delegate. This assessment and any resulting actions must be documented.
