Thanking you, Yours sincerely, For ZF Commercial Vehicle Control Systems India Limited ZF Confidential PRESSE-INFORMATION PRESS RELEASE Page 1/4, September 30, 2026 ZF CVCS India Secures NABL Accreditation for its Hemi Anechoic Chamber, Strengthening Advanced Vehicle Validation Capabilities  ZF's Hemi Anechoic Chamber Testing Laboratory has secured NABL accreditation in accordance with ISO/IEC 17025:2017.  The facility is one of the few such NABL-accredited Hemi Anechoic Chambers in India for automotive Noise, Vibration and Harshness (NVH) testing and validation.  The milestone further strengthens ZF's testing, advanced engineering and validation capabilities, enabling it to support customer requirements across multiple vehicle segments while accelerating development and validation programs for domestic and global vehicle platforms. Chennai, September 30, 2026: ZF Commercial Vehicle Control Systems (CVCS) India Limited has secured accreditation from the National Accreditation Board for Testing and Calibration Laboratories (NABL) for its Hemi Anechoic Chamber Testing Laboratory, located within ZF's approximately 200-acre state-of-the-art proving ground near Chennai. The accreditation makes the facility one of the few NABL-accredited Hemi Anechoic Chambers in India. The NABL accreditation is based on the internationally recognized ISO/IEC 17025:2017 standard and serves as a formal recognition of a laboratory's technical competence, testing methodologies and quality management systems. It provides customers with confidence that test results are accurate, reliable, traceable and generated in accordance with globally recognized laboratory practices. As vehicle technologies evolve through electrification and software-defined architectures, automotive manufacturers are placing greater emphasis on controlling noise and vibration characteristics to improve vehicle quality, customer comfort and regulatory compliance. The accreditation strengthens ZF to support requirements with accurate, repeatable and independently validated acoustic ZF Friedrichshafen AG Global Corporate & Marketing Communications 88038 Friedrichshafen Deutschland · Germany press.zf.com ZF Confidential PRESSE-INFORMATION PRESS RELEASE Page 2/4, September 30, 2026 testing capabilities, while further enhancing the comprehensive testing and validation ecosystem available at its proving ground. ZF's engineering infrastructure in India at Chennai is among a very few NABL- accredited Hemi Anechoic Chambers in the country. The recognition also positions ZF CVCS India as one among a select group of organizations capable of providing independently validated acoustic testing services that meet globally accepted laboratory standards, while supporting the growing validation needs of the automotive industry. The Hemi Anechoic Chamber forms part of one of India's most comprehensive automotive validation ecosystems. The TÜV-certified proving ground, inaugurated in 2001 as India's first privately owned automotive proving ground, supports development, validation and homologation activities across two-wheelers, three- wheelers, passenger vehicles, commercial vehicles and off-highway applications. The proving ground combines advanced acoustic testing capabilities with dedicated ABS/EBS braking tracks, ESC validation infrastructure, high-speed and gradient test tracks, EV charging facilities, workshop and instrumentation support. Together, these capabilities enable end-to-end vehicle and component validation within a single integrated environment. The facility today serves more than 50 customers, including leading OEMs, suppliers and technology partners. The accreditation is valid through July 2030 and supports testing and validation requirements across a wide range of conventional and electrified vehicle technologies, including compressors, pumps, braking systems, steering systems, electric motors and electronic systems. The 144 sq. m Hemi Anechoic Chamber can test vehicles up to five metres in length and 2.5 metres in height under controlled acoustic conditions. With background noise levels below 20 dBA and a 100 Hz cut-off frequency, the facility enables highly precise acoustic characterization and NVH evaluation for modern automotive systems and components. The accredited laboratory further enhances ZF's validation ecosystem, supporting technologies ranging from active and passive safety systems to electrified propulsion solutions. By combining accredited NVH testing with vehicle dynamics, ZF Friedrichshafen AG Global Corporate & Marketing Communications 88038 Friedrichshafen Deutschland · Germany press.zf.com ZF Confidential PRESSE-INFORMATION PRESS RELEASE Page 3/4, September 30, 2026 braking, stability control and durability validation capabilities, ZF helps accelerate development timelines and optimize product performance before vehicles enter series production.
