Relative Accuracy Test Audit (RATA)

Relative Accuracy Test Audits (RATA) are crucial for ensuring the precision and compliance of Continuous Emissions Monitoring Systems (CEMS). By comparing CEMS data with reference method test results, RATA validates system accuracy and ensures adherence to environmental standards.



At AIMS, we deliver comprehensive RATA services, enabling clients to meet stringent regulations such as those from the Environmental Protection Agency (EPA). Our expertise spans the entire emissions monitoring process, ensuring your systems function efficiently and remain fully compliant.
