Expired standard gas may have the following effects on equipment calibration:
First, it may lead to inaccurate reading of the equipment: The use of expired calibration gas for calibration may lead to inaccurate concentration values of the standard gas used for calibration, thus affecting the results of the equipment calibration, resulting in inaccurate reading of the equipment.
Second, lead to equipment failure: if the standard gas expires, it may not meet the specifications recommended by the equipment manufacturer, which may cause the equipment to not work normally, affect the normal operation of the equipment, and in serious cases may lead to equipment failure.
Third, calibration cycle: If the standard gas expires, it may lead to a longer calibration cycle, and the expired standard gas is used, resulting in an abnormal calibration cycle of the equipment. It may be recommended to replace the standard gas and recalibrate the equipment.
Fourth. Waste of resources: Buying expired standard gas can result in wasted money, as it may have lost its value as a calibration medium.
Therefore, in order to avoid these effects, it is recommended to use standard gas within the validity period in order to ensure the quality and accuracy of equipment calibration.
It is recommended to calibrate equipment with standard gases that are fresh and within the shelf life, and pay close attention to their expiration date.
The validity period of the standard gas is usually about one year, but the specific validity period needs to be determined according to the certificate.
In summary, expired standard gases are not suitable for calibration and detection, as their concentration and composition may have changed, affecting the accuracy of the measurement results.
If the expired standard gas is used for calibration, the indicating error of the equipment may increase, which will affect the reliability of the equipment.
In order to ensure the accuracy and reliability of calibration, it is recommended to compare and check the expired standard gas with the newly purchased standard gas when the standard gas is found to be expired.
If the indication error with the new standard gas does not exceed 3%, it can be considered to be still used for calibration, but verification records should be properly kept for reference.
In addition to the above, regular calibration of the detection equipment is also necessary, because the accuracy of the equipment may be affected by the use of the environment, sensor loss and other factors.
