EMC Testing Labs in Chennai – 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.

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.
