Welcome to TCQA Labs, your trusted partner in environmental compliance. We are proud to be India's first and only laboratory offering specialized testing services for the Annual Surveillance Test (AST) of Continuous Emission Monitoring Systems (CEMS). Our unique expertise and indigenously developed state-of-the-art facilities ensure that your emissions monitoring equipment meets the highest national and international standards.
The Annual Surveillance Test (AST) is a crucial on-site functional check performed once a year. It is carried out to ensure the CEMS remains within its valid calibration range and continues to operate correctly in its real-world environment. The AST verifies the continued performance and stability of the CEMS over time, which is essential for ongoing regulatory compliance and maintaining the integrity of your emissions data.
The Central Pollution Control Board (CPCB) in India mandates the regular, ongoing performance monitoring of CEMS.
Our AST services align directly with these CPCB guidelines, providing your facility with verified, credible, and legally defensible data for continuous compliance.
This European standard provides the framework for the quality assurance of CEMS, defining the three core levels (QAL1, QAL2, QAL3) and the mandatory Annual Surveillance Test (AST).
Our AST validation is conducted in strict accordance with DIN EN 14181 to ensure your system performs correctly year after year.
The AST involves a parallel comparison of the CEMS reading against a Standard Reference Method (SRM). We utilize methods from standards such as CEN/TS 17021 (SO2), EN 14792 (NOx), EN 14789 (O2), CEN/TS 17405 (CO2) and EN 15058 (CO), which detail the performance of SRMs, to ensure the highest level of accuracy and regulatory acceptance for your surveillance.
We bring global standards like EN 14181 and European SRM Methods to your doorstep. Our team of experts understands both international best practices and the specific requirements in the context of Indian tropical conditions, as well as Indian regulatory requirements.
Our AST includes a full suite of on-site functional checks to ensure your CEMS is performing accurately and reliably, a year after its initial validation.
Our services provide independent, third-party assurance of your CEMS's continued accuracy and reliability, which is essential for building and maintaining trust and credibility with regulatory bodies like the CPCB over the long term.
By ensuring your CEMS is properly checked annually, we help you avoid potential fines, legal issues, and operational shutdowns that can result from a CEMS that drifts out of calibration over time.
Quality is at the heart of everything we do.
ISO/IEC 17025 Accreditation: We are an ISO/IEC 17025 accredited testing laboratory by the International Accreditation Service (IAS, USA), an ILAC member, a globally recognized body. This is the standard for labs worldwide, proving our technical competence and ability to produce precise and accurate data. It also validates our technical capabilities and the international acceptance of our test reports.
