ENVIRA performs the maintenance of emission analyzers in accordance to Standard UNE-EN 14181:2015.
Maintenance of large emission sources
ENVIRA has extensive experience in this kind of maintenance and for this purpose we have developed a software tool to monitor and store information at Quality Assurance Level 3. This software has been installed in many centrals and emission systems where the standard UNE 14181 is applicable. The regularity of QAL3 must fit the maintenance interval and the acceptance criteria for SAM calibration.
Periodical verifications of zero and range in the SAM
A SAM can be altered or become less accurate after some time. The purpose of the verifications is maintaining and proving the quality of the SAM so that it complies with the repeatability requirement of zero and range and the drift values during the operation and the SAM are in the same operational condition as when it was installed. This will be achieved by checking that the drift and the accuracy established during the QAL1 are still under control. The procedures for assessing the SAM determine whether it is still apt to perform measurements.
