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 QAL2 validation 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.
QAL2 (Quality Assurance Level 2) is a crucial on-site functional and calibration test. It is performed after a CEMS has been installed to ensure that the system operates correctly in its real-world environment. A QAL2 test validates that the CEMS is capable of meeting all the technical and performance requirements of relevant standards and establishes the calibration function for the CEMS. Without a valid QAL2, your CEMS data may not be considered reliable for regulatory purposes.
The Central Pollution Control Board (CPCB) in India mandates the periodic performance validation of CEMS. Our QAL2 validation services align directly with these CPCB guidelines, providing your facility with verified, credible, and legally defensible data for ongoing compliance.
This European standard provides the framework for the quality assurance of CEMS, defining the three core levels (QAL1, QAL2, QAL3). Our QAL2 validation is conducted in strict accordance with DIN EN 14181 to ensure your system performs correctly over time and maintains its suitability.
The QAL2 test 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 validation.
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 QAL2 validation includes a full suite of on-site functional and calibration tests to ensure your CEMS is performing accurately and reliably in its operational environment.
Our services provide independent, third-party assurance of your CEMS's accuracy and reliability, which is essential for building trust and credibility with regulatory bodies like the CPCB.
By ensuring your CEMS is properly validated and calibrated, we help you avoid potential fines, legal issues, and operational shutdowns that can result from inaccurate or unvalidated emissions data.
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.
