What is Calibration?

Introduction

Whether in scientific research, manufacturing, or daily business operations, the reliability of measurements is crucial. Calibration plays a central role in achieving accurate and consistent results. Without proper calibration, tools, instruments, and devices can produce incorrect readings, leading to costly errors or product failures.

Definition

Simply put, calibration is the comparison of measurement values delivered by a device under test against a standard. This is usually another measurement device of a known value and higher accuracy, with a common example being the gauge block from manufacturers such as Mitutoyo.

The outcome of the comparison can result in one of the following:

• No significant error being noted on the device under test.
• A significant error being noted but no adjustment made.
• An adjustment made to correct the error to an acceptable level.

Strictly speaking, the term “calibration” means just the act of comparison and does not include any subsequent adjustment.
The calibration standard is normally traceable to a national or international standard held by a metrology body.

For Singapore, this standard is usually SAC-SINGLAS given by the Singapore Accreditation Council(SAC) which is based on the internationally recognized ISO/IEC 17025.The SAC will regularly audit labs to ensure they fulfill stringent requirements such as being carried out in a controlled environment and follow certain guidelines and procedures. Only labs that pass will be given the SINGLAS accreditation.

How Often Should Calibration Be Done?

The generally accepted frequency is 12 months. However it can depend on various factors, including:

• Industry Requirements: Some industries, like pharmaceuticals or food production, have stringent calibration schedules to ensure product safety and compliance with regulations.
• Instrument Usage: Instruments that are used frequently or in harsh environments may need to send for calibrations more often than those that are rarely used. We do have customers that request 24mths intervals instead.
• Manufacturer Recommendations: Always refer to the manufacturer’s guidelines for recommended calibration intervals, but consider adjusting based on your specific use case.

Conclusion

Calibration is a cornerstone of maintaining quality, safety, and efficiency across various industries. Whether in a laboratory, manufacturing environment, or healthcare setting, ensuring your equipment is calibrated is essential for reliable results.

By implementing regular calibration practices, you not only comply with industry standards but also protect your operations from costly errors. This will enhance the overall performance of your devices and processes.
