The Central Pollution Control Board (CPCB) has set a final deadline of September 15, 2025, for all manufacturers of Continuous Emission Monitoring Systems (CEMS) to submit their applications for product certification to the National Physical Laboratory (NPL). This notice serves as a continuation of previous announcements and meetings with manufacturers regarding the new certification scheme.
Under the new CSIR – NPL India Certification Scheme (NPLI CS), manufacturers must apply for Air Pollution Monitoring Equipment Product Certification. Failure to submit the application by the deadline will result in their CEMS being derecognized for use with the CPCB’s OCEMS portal. This measure is intended to standardize the quality of air pollution monitoring equipment used by industries.
