RATA Testing Services
Verifying CEMS Accuracy With Precision and Proof
Accurate emissions testing is essential to maintaining confidence in Continuous Emissions Monitoring Systems (CEMS). TriCore Industrial Measurement Services performs Relative Accuracy Test Audits (RATA) to verify the accuracy, reliability, and regulatory compliance of CEMS against approved reference methods.
Our RATA testing programs combine field experience, precision instrumentation, and disciplined test execution to provide defensible confirmation of system performance. Whether supporting an initial certification requirement, a periodic audit, or post-maintenance verification, TriCore helps facilities confirm that monitored emissions data remains accurate, traceable, and acceptable for regulatory use.

Comprehensive RATA Testing Services
Our services include:
Relative Accuracy Test Audits (RATA): Direct comparison of CEMS data to reference method results to verify monitor accuracy and confirm system validity under required regulatory procedures.
Reference Method Testing Coordination: Execution of field testing using accepted methodologies and disciplined sampling procedures to produce defensible comparison data.
Performance Verification: Evaluation of emissions monitor performance under actual process conditions to confirm that the system remains within allowable accuracy criteria.
Post-Maintenance and Modification Support: RATA support following major system changes, repairs, replacements, or other events that require renewed confidence in monitor performance.
Documentation & Reporting: Comprehensive reporting packages that document field procedures, results, calculations, and final conclusions for compliance and audit support.
TriCore technicians bring field-tested experience to each audit, helping ensure that every RATA is traceable, well documented, and executed with attention to data quality and regulatory defensibility.
Testing Methodologies and Standards
RATA testing depends on controlled field execution, accurate reference methods, and disciplined documentation. TriCore performs emissions testing using calibrated instrumentation and proven procedures so that comparison results are meaningful, repeatable, and suitable for compliance review.
Our approach is centered on measurement integrity from start to finish, including preparation, field execution, data review, and final reporting. This helps facilities demonstrate that their CEMS data is not only available, but validated against recognized testing procedures.
Integrated Reporting and Compliance Support
RATA results are most valuable when they are clearly documented and easy to incorporate into broader compliance workflows. TriCore supports emissions testing with organized reporting and compliance-focused documentation so facilities can maintain visibility into audit performance and preserve records for internal review or regulatory submission.
A structured reporting approach helps environmental teams, plant personnel, and compliance stakeholders review results efficiently and maintain confidence in the data supporting the emissions program.
Validated Data. Verified Compliance.
TriCore’s RATA testing services help facilities confirm that CEMS and analyzer systems are producing accurate, defensible emissions data under real operating conditions. With disciplined field execution, organized reporting, and a strong focus on data quality, TriCore delivers RATA support that strengthens confidence in compliance performance and system reliability.
