EMC Testing Labs in Tamil Nadu – Accredited Facilities

ARRAA Labs (ARRAA Energy Pvt Ltd)

Website →

ARRAA Labs, operated by ARRAA Energy Pvt Ltd, is a NABL-accredited testing laboratory at Kundrathur on the south-western edge of Chennai, Tamil Nadu, and is one of the newer independent EMC facilities serving southern India's electronics and automotive supply base. It is built as a single-roof compliance house: EMI and EMC measurement sits alongside environmental simulation, vibration and durability testing, relay testing, and product inspection and certification support, so a manufacturer can take a product through electromagnetic, climatic and mechanical qualification in one engagement rather than coordinating three vendors - a point its customers single out, along with reliable turnaround against promised dates. The laboratory is NABL accredited, which in India means assessment to ISO/IEC 17025 by the National Accreditation Board for Testing and Calibration Laboratories, and the facility is recent, with modern instrumentation installed rather than inherited. Testing covers the conducted and radiated emission measurements and the full IEC 61000-4 immunity series that underpin Indian IS standards, CE marking and the automotive AIS requirements, with vehicle-level and component automotive work supported alongside the industrial and medical caseload. Specialisations are electrical and electronic product compliance, automotive vehicle and component testing, medical equipment, protection relays, and combined EMC with vibration and environmental qualification.

Cosmic Compliance Test Lab (CCTL)

Cosmic Compliance Test Lab is a NABL-accredited EMC house to ISO/IEC 17025:2017 with laboratories at Bommasandra on the southern industrial belt of Bengaluru and at the Annamalai Industrial Park in Kalapatti, Coimbatore. Although young - around five years of operation, with more than five hundred clients and a hundred and twenty projects reported - its chamber specification is serious: a component semi-anechoic chamber covering 10 kHz to 40 GHz and, separately, a vehicle semi-anechoic chamber with a two metre turntable, which puts whole electronic sub-assemblies and small vehicles inside a chamber rather than restricting the site to board-level work. Shielded control rooms support both, and an EMC scanner is in commissioning. The accredited programme spans CISPR 25 for automotive components, MIL-STD-461 including the RE102 radiated emission and bulk current injection methods, the IEC 61000 commercial and industrial series, and EN 50121 for railway equipment, with electrical fast transient and radiated emission and immunity across the range. The laboratory also holds a Designated Test Facility certificate. The 40 GHz ceiling paired with vehicle-level capability is an unusual combination at this scale in India, and customers single out developmental testing support, documentation help and cost relative to the larger international houses. Specialisations are automotive electronic sub-assembly EMC, aerospace and military MIL-STD-461 programmes, railway equipment, telecom and wireless products, and industrial, scientific and medical equipment.

GARC - Global Automotive Research Centre, EMC Facility

Website →

The Global Automotive Research Centre at Oragadam in the SIPCOT Industrial Growth Centre near Chennai is a Government of India automotive test and homologation centre established under the NATRiP programme, and its electromagnetic compatibility facility is the largest vehicle-level EMC installation in this directory. Two absorber-lined semi-anechoic enclosures dominate it: one measuring 30 by 20 by 10 metres with an 11 metre diameter turntable, the other 19.5 by 12 by 8 metres with a 6 metre turntable, both integrated with four-wheel-drive chassis dynamometers so a vehicle can be run under load inside the chamber. Vehicle-level radiated emission measurement covers 30 MHz to 18 GHz off-board and 1.8 MHz to 2 GHz on-board, and radiated immunity runs from 100 kHz to 18 GHz at field strengths up to 200 V/m - across two-wheelers, three-wheelers, passenger cars and light and heavy commercial vehicles, to AIS 004 Part 3, CISPR 12, CISPR 25 and ECE R10. Component-level capability is equally complete: ALSE chambers plus TEM cell, stripline and tri-plate methods, bulk current injection from 1 MHz to 3 GHz with current probes to 300 mA and a tubular wave coupler above 400 MHz, conducted emission by voltage and current probe methods, conducted transient immunity on 12, 24 and 48 volt systems to 100 amperes generating the full ISO 7637 pulse set, ESD to 30 kV air and contact per ISO 10605, and ISO 16750-2 power supply tests. Commercial equipment testing covers harmonics and flicker to 75 amperes, EFT to 4 kV and surge to 6 kV. Altair FEKO simulation supports antenna placement design. Two further component ALSE chambers and an EV charging test environment rated to 720 kW and 1000 A DC are in commissioning. Specialisations are vehicle-level EMC and homologation, electric vehicle and EVSE testing, electronic sub-assembly qualification, and automotive OEM specification programmes.

Thiagarajar Telekom Solutions Ltd (TTSL)

Website →

Thiagarajar Telekom Solutions is an RF and microwave engineering company at the Thiagarajar Advanced Research Centre in Thiruparankundram near Madurai, Tamil Nadu, incubated out of the TIFAC-CORE centre at Thiagarajar College of Engineering and carrying what it describes as twenty-five years of accumulated research and development experience in RF and microwaves. Its test offering follows from that engineering base rather than from a compliance-house model: antenna testing, RF testing, EMI and EMC testing and electromagnetic field (EMF) measurement, supported by design capability in antennas, RF components and systems, and transmitter and receiver architectures. The combination of antenna characterisation alongside EMC measurement is relatively rare in India and useful where a radio product's emission problem and its antenna performance share a root cause - the company works on both sides of that boundary. Alongside testing it provides antenna and RF design consultancy and runs customised training programmes in antennas, RF and baseband processing, reflecting its academic origins. The company publishes no NABL or ISO/IEC 17025 accreditation and does not detail its chamber specification, so it is recorded here without an accreditation entry and with a conservative test list; it is best understood as an RF and EMC engineering and measurement house rather than an accredited certification laboratory, and its current scope should be confirmed directly. Specialisations are antenna design and measurement, RF and microwave system design, EMF exposure measurement, and RF engineering training.
