National Emissions Test Centre: Why was it established?


The National Emissions Test Centre (NETC), located in Rawang, is the first full-fledged vehicle emissions testing facility in Malaysia. NETC is operated by the Malaysia Automotive, Robotics and IoT Institute (MARii) and first began operations in 2018. The NETC is also a testament of a successful technology transfer from Daihatsu to Perodua Auto Corporation Sdn Bhd with MARii as the partner.

NETC has now been assessed in accordance with the internationally recognised standard – ISO/IEC17025:2017. This standard is the general requirements for the Competence of Testing and Calibration Laboratories with the scope of Automotive Emission and Fuel Consumption Testing.

The scope of certification as per below:

  • Testing according to UN-R83 until series of Amendment 07
  • Testing according to UN-r101 until series of Amendment 01
  • Testing according to JC08 (JPN2009)


Objectives of NETC’s establishment

The establishment of NETC addresses the importance of carbon emission reduction, especially in automotive sector. The test centre is open to public including the government, car manufacturers (OEM), research institutions, academia and companies in the private sector.

NETC is also recognised by TUV Rheinland (a technical service specialist from Germany that provides inspection and product certification services) to conduct emissions testing, especially for certification purposes – Vehicle Type Approval (VTA) and Energy Efficient Vehicle (EEV) certification.

All NETC staffs and operators are highly skilled, trained and recognised as certified drivers to conduct the emissions testing.

MARii’s initiative, with the help of its partners, promotes the usage of EEVs and has set aims for Malaysia to be an EEV hub by the year 2020 – in-line with the government’s objectives according to the National Automotive Policy (NAP).


Facilities that are available for use

The centre’s facilities include real-time measurement of exhaust emission gases for passenger cars in accordance to the standards as stated above.


Emission Chassis Dynamometer


A chassis dynamometer is a test equipment fitted with rollers for the wheels of a vehicle, that is capable of providing drive input and measuring output such as power and torque that is produced by the engine. The chassis dynamometer is capable of reproducing the load and inertia of the vehicle similar as to when driven on a road. This is essential in measuring the exact value of gasses that are emitted from the vehicle according to various road conditions.


Soak Room

The soak room is a drive-in temperature and humidity-controlled environmental room designed for testing vehicles. Vehicles undergoing testing must be placed in the room (soaked) between 6-36 hours prior testing. Soak tests are primarily used to check the reaction of a subject under test – in this case, the emission of gasses and fuel consumption of the tested vehicle, in a simulated environment. The observations made during this period are used to improve the characteristics of the subject under further tests.


Emission Room

The emission room is used to collect data on the gasses that are being emitted from the tested vehicle. Data such as weight and concentration of the emitted gasses are collected and will analysed in the control room to see how they comply to the standards and regulations mentioned above.


Control Room

The control room houses high-performance computers to analyse the captured data from the emission room for further evaluation and research. The high-performance computers also provide real-time data of the gasses being emitted from the tested vehicle during the test session. With real-time data acquisition, the control room operator can gain insights as to when a problem occurs during the test period.


Types of testing that can be conducted in NETC

VTA and Certification

  • UN R83 (emission pollutant)
  • UN R101 (fuel consumption)
  • EEV certification

Conformity of Production (COP)

  • For vehicle emission

R&D Testing

  • Tailpipe exhaust emission
  • Fuel consumption
  • Material testing
  • Air-conditioning performance


Currently, NETC is the most advanced emissions testing facility within the ASEAN region. NETC is capable of measuring up to Euro 6d Emission Standard by using Worldwide Harmonized Light Duty Driving Cycle (WLTC) – a test procedure that defines a global harmonized standard for determining the levels of pollutants and CO2 emissions, fuel or energy consumption and electric range from light duty vehicles (passenger cars and light commercial vans).

In the future, NETC will be expanded to include motorcycles and commercial vehicles emission testing, including diesel-based powertrains.
