Electro Magnetic Compatibility

Electro-magnetic Compatibility (EMC) may be defined as “the ability of an electronic system to function properly in its intended electromagnetic environment, and to not contribute interference to other systems.” The goal is to have the electronic system be immune from the emissions of other systems, not interfere with the operation of other systems, and not interfere with its own operations.

Our EMC laboratory, a Centre of Excellence for EMC/EMI testing by NATRIP offers state of the art testing facilities for compliance and pre-compliance testing at both vehicle and component level.

Test chambers:

Two vehicle test chambers and two components test chamber are being established currently.

  1.  Whole vehicle Semi-Anechoic chamber
  2.  Two/Three wheeler Semi-Anechoic chamber
  3.  Component Test Chamber

The chambers comply:

  1.  Normalized site attenuation: Standard EN 50147-2/ANSI C63.4-2001
  2.  CISPR 16-1-4 Site VSWR
  3.  Field uniformity on chassis dynamometer: EN 61000-4-3+ A1, ISO 11451-2:2005
  4.  Shielding performance: EN50147-1/IEEE299
  5.  Filter Performance: MIL-STD-220
  6.  Environmental noise: CISPR25:2002 standards through CISPR25 & CISPR12 methods
  7.  Indian Automotive Standard: AIS-004/1999
  8.  Directive 2004/104/EC-2006/28/EC – Whole vehicle and electric/electronic subassemblies (ESAs)
  9.  ECE 10R02 Regulation – Radiated Emission/Immunity 2/3 wheelers, Whole vehicle and electric/electronic sub-assemblies (ESAs)
  10.  Directive 97/24/EC – Radiated Emission/Immunity 2/3 Wheelers, Whole Vehicle and electric/electronic sub-assemblies (ESAs)
  11.  OEM standards of Ford, GM, PSA (Peugeot – Citroen), BMW, Fiat, Chrysler, Honda, Mitsubishi and Mercedes-Benz

GARC has a state of the art facility to conduct EMI/ EMC development and certification tests on vehicles and automotive electrical/electronic components. The facility includes two semi anechoic chambers, one for heavy vehicles / cars and another for two wheelers, three wheelers and components. A separate component test lab is also available for conducting tests on electronic sub-assemblies. The test systems have capability up to 18 GHz for radiated emissions and radiated immunity. Both the chambers shall be used for compliance tests as per AIS 004, CISPR and ECE R10 and other standards. Developmental tests as per OEM’s requirements shall also be conducted at our facility.

1.Large semi-anechoic chamber of dimension 30m x 20m x10m with 4×4 chassis dyno of 167 kw on 11m diameter turntable having load capacity of 19 ton.

2.Small semi-anechoic chamber of dimension 19.5m x 12m x 8m with chassis dyno of 167 kw on 6 m diameter turntable having load capacity of 4 ton.
