Quality Assurance Level 1
it is a suitability test that ensures a CEMS is capable of meeting all the technical and performance requirements of the relevant standards before it is installed in Industry.
Quality Assurance Level 2
It is performed after a CEMS has been installed to ensure that the system operates correctly in its real-world environment.
Quality Assurance Level 3
It is a routine quality control check to demonstrate that the CEMS's performance remains within the required limits over time, ensuring continued correct operation in its real-world environment.
Annual Surveillance Test
It is carried out to ensure the CEMS remains within its valid calibration range and continues to operate correctly in its real-world environment.
Standard Reference Methods
They are used to perform the Relative Accuracy Test Audit (RATA) for a Continuous Emission Monitoring System (CEMS).
Homogeneity test
It is the first step in characterizing a homogeneity in stack to ensure that subsequent measurements (like the AST or QAL2 accurately represent the total emission load.
