A direct translation of the word ‘accreditation’ is providing trust. To measure this form of trust, standards are made to measure the expertise, impartiality and the level of continuous improvement of an organization. Laboratories that are accredited to the international standard ISO/IEC 17025:2005 have demonstrated that they are technically competent and able to produce precise and accurate test and/or calibration data.
Why are precise and accurate measurements important? For an example: If you pay the bill at the fuel station you trust that the amount you have to pay is an accurate equivalent of the amount of fuel which you filled-up. The same counts for many additional processes in which measurement equipment are used to secure the outcome of your process. An ISO/IEC 17025:2005 test certificate is the highest international level of calibration security which can be provided for measurement equipment. Bronkhorst is a proud owner of an accredited in-house ISO/IEC 17025:2005 Calibration Centre (BCC).
In this week’s blog I would like to take you with me to get a glance at our Bronkhorst Calibration Centre (BCC). This has been accredited since 2010 for gas, pressure and liquid flow calibration services.
For this, I followed Mandy Westhoff, one of our calibration centre operators, during her daily routines to get a realistic view on the activities of the calibration centre.
In general, all flow meters will be calibrated as a final step in production. The instrument with certain parameters will be compared with a fixed reference in certain environmental conditions, to provide real flow measurements.
Measuring equipment is used to secure the outcome of a process, process owners have to be able to rely on these measurements where high accuracy and – more and more – traceability play an important role, for example in the Pharmaceutical market. It is a way of risk management.
Throughout the years, we have noticed a distinctive increase in ISO/IEC17025:2005 calibrations in our calibration centre. An ISO/IEC 17025 calibration is often required as this is the highest level of calibration available in the market.
The Bronkhorst Calibration Centre is an independent department within the Bronkhorst organization and therefore not subjected to any commercial influences whatsoever.
It can be said that the tasks of the calibration centre are twofold:
The scope of the calibration centre includes calibration of gas flow, liquid flow and pressure.
About 60-70% of the performed ISO/IEC 17025:2005 calibrations are ‘as found’ calibrations on used instruments. Many of our customers, especially in the Pharmaceutical market, Universities and Automotive industry, will send their instruments once a year for calibration. So they have a reliable instrument calibrated according to the highest level of calibration security which they can use as a reference for their own calibrations on-site.
To offer the highest standard of precise and accurate test and/or calibration data the environment of the laboratory is fully controlled. The calibration will be executed in a high-tech lab under conditioned circumstances by 21°C ± 2°C and a humidity of 50 ± 20%, which is outstanding. Even sunlight through the windows has been avoided and movement of people has been minimised as much as possible. Non-authorized personnel is not allowed to enter the calibration centre.
After the acclimatisation process and setup, the operator will conduct a leakage test using the Flowbus Piston Prover (FPP). This test will be done prior to every calibration as a security check to maintain the high level of quality assurance.
After approval of the environmental conditions, the calibration starts. A standard calibration is performed on several measurement points. On these measuring points the accuracy of the instrument will be determined.
After a successful calibration the instrument is provided with a label mentioning the date of calibration and certificate number, so all can be traced back to the calibration dossier. The BCC coordinator will check if everything is done by protocol and all ISO/IEC 17025:2005 calibration dossiers will be sent to the BCC Officer to perform a final check.
