National Automotive Testing and R&D Infrastructure Project (NATRiP)

The National Automotive Testing and R&D Infrastructure Project (NATRiP) is the largest and one of the most significant initiatives in the automotive industry in India, representing a unique collaboration between the Government of India, a number of State Governments, and the Indian Automotive Industry.NATRiP is responsible for a new state-of-the-art testing, validation, and R&D project created to support the rapidly growing automotive industry in India.

NATRiP selected ETS‑Lindgren, a world leader in the design and installation of automotive EMC test chambers, to provide this one-of-a-kind test facility. With numerous automotive EMC test chambers provided to notable companies such as General Motors (GM), Ford Motor Company, Honda, and Chrysler, to name just a few of its prominent automotive customers, ETS‑Lindgren’s proven expertise encouraged a successful partnership.

The NATRiP project includes two major automotive EMC test facilities near the automotive manufacturing hubs in India. One is located in Manesar (near Gurgaon, National Capital Region) and the other is located in Orgadam, on the outskirts of Chennai. Both facilities have one large 10 m chamber for full vehicle testing with an 11m diameter chassis dynamometer turntable for testing of large and small vehicles. The Chennai facility also has a smaller EMC test chamber with a 6 m diameter chassis dynamometer turntable for testing motorcycles, three wheeled vehicles and automotive components.

RF Shielded Chassis Dynamometer Pit Rooms

An RF shielded dynamometer pit room is located underground in each facility basement below the ten-meter chamber. The rooms are lined (floor and walls) with welded steel.

Full Vehicle Chassis Dynamometer System

A four wheel full vehicle chassis dynamometer turntable was installed in each ten-meter chamber capable of a maximum axle load in the track area of 9,000 kg (19,842 lb); maximum turntable load is 19,000 kg (41,888lb) total.

Entire Facility Technical Features

• Capable of performing EMC tests on vehicles from two wheelers up to Heavy Commercial Vehicles (HCV). CISPR 16-1-4: Site VSWR (SVSWR) testing from 1 GHz to 18 GHz at 3 m (10 ft) range, with a test volume of 2 m (7 ft) diameter.
• CISPR 25 Ed 3: Better than 6 dB between 70 MHz and 2500 MHz.
• Constructed of ETS‑Lindgren Series 101™ pan-shield type lightweight, modular shielding panels. ISPR 25 Ed 4 (Draft): 150 kHz to 1 GHz, Long Wire compliant.
