Why Calibration Matters in Leak Testing
Leak testing instruments that are properly calibrated give results you can truly trust. They also reduce the risk of product recalls and help you comply with regulations. At ATEQ Canada, our calibration services are ISO 17025-approved, which means companies can be sure their leak testers are up to global accuracy and performance standards. Calibration isn’t just something you do now and then—you want it to be a key part of your maintenance strategy.
ISO 17025 Accredited Laboratory: Why is it Important
ISO/IEC 17025 approval is the “gold standard” for calibration places:
- Measurements that match national standards
- Qualified staff who know what they are doing
- Calibration datas that are good and true
- Test items that are handled and moved right
- Test tools that are kept up
- Controlled calibration environments
Regular testing makes sure approved labs stay a good pick for companies that want things right every time.
How Often to Calibrate & Ways to Do It Well
Normal: most leak testers should be checked once a year
Often-used tools: might need checking more
Key uses: critical equipment, such as airbags or pacemakers, often require shorter intervals between calibrations.
Signs you might need to check sooner:
- Testing that doesn’t match up
- Tool errors
- Failed checks or bad products
- Tools that have been moved or changed
Additional Tips:
- Keep a record of the last calibration date
- Set up reminders for regular checks
- Use ISO/IEC 17025–accredited laboratories
