Types of Emission Tests Conducted for Your Vehicle in Kerala

Undergoing the following tests is crucial to ensure that vehicles in Kerala adhere to environmental regulations.

  • Smoke Meter Test (for Diesel Vehicles): This test checks how dark the smoke from diesel vehicles is. It ensures the smoke is within acceptable limits, as darker smoke means more pollution.
     
  • Gas Analyser Test (for Petrol and CNG Vehicles): This test measures harmful gases like carbon monoxide (CO), hydrocarbons (HC), and nitrogen oxides (NOx) from petrol and CNG vehicles. It ensures that the emissions meet the required standards.
     
  • Evaporative Emission Test (for All Vehicles): This test checks for fuel vapour leaks from the vehicle’s fuel system. It ensures harmful vapours are not released into the air.
     
  • Idle Speed Test (for Petrol Vehicles): This test checks the emissions from petrol vehicles while idling (not moving). It ensures pollutants stay within safe limits.
     
  • Exhaust Emission Test (for Two-Wheelers and Four-Wheelers): This test measures the gases coming from the exhaust of two-wheelers and four-wheelers. It ensures the emissions follow pollution control rules.
     
  • Smoke Density Test (for Commercial Vehicles): This test checks how much smoke is released by heavy vehicles like trucks and buses. It ensures they stay within pollution limits to reduce air pollution.

Emission Test Procedure to Get PUC Certificate in Kerala

Obtaining a PUC certificate in Kerala involves passing an emission test, which ensures your vehicle complies with environmental standards. 

At the testing centre, the following procedure is typically followed:

  1. Vehicle Inspection: The vehicle undergoes a physical check to ensure the exhaust system functions correctly.
     
  2. Emission Measurement: A specialised machine measures the pollutants emitted from the exhaust. The engine is tested at various RPMs (revolutions per minute) to evaluate emissions at different speeds.
     
  3. Result Analysis: The results are assessed to verify if the vehicle meets pollution control standards. The car passes the test if the emissions are within the permissible limits.
     
  4. Issuance of PUC Certificate: Upon passing the test, a PUC certificate is issued detailing the test date, results, and validity period, typically 6 months or 1 year.

PUC Certificate Renewal in Kerala

Keeping your vehicle’s emissions in check is essential for maintaining a healthy engine. Clogged filters, poor combustion, or faulty engine components could cause high emission levels. Regularly renewing your PUC certificate ensures issues are identified and resolved, helping your vehicle run smoothly. Additionally, a valid PUC certificate reduces harmful pollutants, protects public health and promotes awareness about the importance of controlling vehicle emissions.

PUC Certificate Validity in Kerala

The validity of a PUC certificate in Kerala is determined by the vehicle type and its emission standards:

For new vehicles adhering to BS-IV and above emission standards, the PUC certificate is valid for one year from the date of issuance. In contrast, older cars that follow pre-BS IV standards have a certificate validity of six months from the date of issuance.

Importance of Maintaining a Valid PUC Certificate

A valid PUC certificate shows that your vehicle's emissions are within the limits set by the Indian government. It helps identify if your car contributes to air pollution and makes it easier to take corrective actions. Fixing emission issues ensures your vehicle runs efficiently and lasts longer. In Kerala, not having a valid PUC certificate can result in heavy fines, so regular renewal helps you avoid these penalties.
