What is the recommended calibration frequency for xenon lamp aging test chambers?

2023-06-26 11:03

The recommended calibration frequency for xenon lamp aging test chambers can vary depending on several factors, including the manufacturer's recommendations, the specific model of the test chamber, and the test standard being used. In general, it is recommended to calibrate the test chamber at least once a year or after a specific number of testing hours, whichever comes first.

Calibration of xenon lamp aging test chambers involves checking and adjusting the chamber's key parameters, such as irradiance level, temperature, and humidity, to ensure that they are within the specified range and consistent with the requirements of the test standard being used. Calibration also involves checking the accuracy of the sensors and other instrumentation used in the test chamber.

Some test standards may have specific requirements for calibration frequency and procedures. For example, the ASTM G155 standard recommends that xenon lamp aging test chambers be calibrated at least once a year or after every 500 hours of operation, whichever comes first. The ISO 4892 standard recommends that the test chamber be calibrated at least once a year or after every 500 hours of operation, and that the calibration be performed by a qualified technician.

It is important to follow the manufacturer's recommendations and the requirements of the test standard being used for calibration frequency and procedures to ensure that the test chamber is operating correctly and producing accurate and reliable test results. Regular calibration checks can help to identify any discrepancies in the chamber's performance and allow for adjustments to be made to maintain accurate test conditions.
