Here are the frequently asked questions that you might help you to choose a suitable calibration laboratory. You may also check out with the Calibration Services, Calibration And Measurement and the value added services that SIRIM Standards Technology  provided.


What is Calibration?

It is an activity where the instrument being tested is compared to a known reference value/higher reference standard. 

Why is calibration important?

Calibration helps to minimise measurement uncertainty and improve the accuracy of the measuring equipment so that the measurements taken are accurate and reliable.

On top of that, this calibration supports the standard requirement needs where the precision of instruments is required for demonstration of compliance to, such as ISO 9001, 14001, 18001, ISO/TS 16949 and etc.

Does every instrument need to be calibrated?

Not all instruments need to be calibrated. Only those instruments that used for measuring purposes or having measurement element on it that impacts the Quality of Product/Service should be calibrated.

If you are unsure whether your instruments can be calibrated or not, you may send your equipment name, model number, range and other details through “Request for Quotation” button above or contact us at . We will be happy to assist you.

Where should I send my equipment for calibration?

You can send to SIRIM Standards Technology at our branches, as our laboratories are accredited to ISO/IEC 17025.

Accreditation to ISO/IEC 17025, means;
  • Our management system meets international standards requirements, technical staff is competent, the measuring standards used are reliable and measuring data is traceable. 

Am I making the right decision if I select the calibration lab which offers the cheapest fee?

Cheap is not always necessarily good.

In calibration services, the calibration fee and turnaround time are determined by;

  • Complexity of calibration standard equipment that used for calibration
  • Calibration protocol as required by international standards
  • Minimum time required for preparation of some calibrations (e.g. soaking time for most of Dimensional items is from 8 hours to 24 hours).
  • Total time taken to perform the calibration
  • Calibration process (manual or automated)
  • Technical requirements e.g. uncertainty in calculation/analysis, adjustment and so on
