Why do we need to calibrate the salt spray chamber?
As a standardized testing process, we need to ensure that the salt spray chamber has the ability to create the correct conditions, and we also need to ensure that the salt spray tests performed meet the requirements of the relevant standards.
When do I need to calibrate my salt spray chamber?
1) When we have not done salt spray test for a long time.
2) When we repair, maintain or transport the salt spray chamber.
3) When we find that the test results are obviously incorrect.
How to calibrate a salt spray chamber?
Two ways:
1) Self-calibration.
Salt spray chamber manufacturers always provide calibration kits. Follow the manufacturer's instructions for the calibration process. The following data shall be continuously measured and recorded over 16 hours.
1.1 Temperature.
1.2 fog volume.
1.3 Solution concentration.
1.4 Solution pH.
1.5 solution specific gravity.
2) Calibrated by a third-party laboratory.
Laboratories should have detailed and standardized procedures for performing such calibrations and should issue detailed calibration certificates. Accredited laboratory required.
