What is a PUC Certificate?
A Pollution Under Control (PUC) certificate has to be obtained for vehicles that fulfil the government's prescribed emission levels. Such a certificate is an assurance that the emission of exhaust fumes by the vehicle lies within the specified limits defined to combat environmental pollution caused by the emission of vehicles.
In India, all motor vehicles, including two-wheelers, cars, and commercial vehicles, are required to get their vehicles inspected under the PUC scheme. The checks are performed at regular intervals to verify if the vehicles are within the limits of the pollution norms laid down by the government. The PUC certificates are generally valid for six months, after which the vehicle is required to take another test for emission code compliance.

Types of Emission Tests Conducted for Your Vehicle in Rajasthan
The emission tests for Rajasthan are basically a point at which vehicles have to check in to ensure that they meet the environmental regulations set forth by the government regarding the pollutants from the exhaust. Emission testing is classified as:
- Smoke Meter Test (for Diesel Vehicles): The opacity of exhaust smoke produced by diesel vehicles is measured to make sure it doesn't exceed the limits of permissible pollutants. High opacity indicates increasing levels of pollution.
- Gas Analyser Test (for Petrol and CNG Vehicles): It measures the harmful gases, namely, carbon monoxide (CO), hydrocarbons (HC), and nitrogen oxides (NOx) emitted from petrol and CNG vehicles-will stay up to legal parameters.
- Evaporative Emission Test for All Vehicles: This test is meant to test leaks of vapours in the vehicle's fuel system, ensuring that vapours harmful to the earth's atmosphere are not released.
- Idle Speed Test for Petrol Cars: This test checks whether or not the emissions of a petrol vehicle are within permissible limits when at rest.
- Exhaust Emission Test for Two and Four-Wheelers: This process inspects the exhaust system and tests with a gas analyser to see if both two-wheelers and part called four-wheelers meet the pollution control norms.
- Smoke Density Test for Commercial Vehicles: It is used mainly to measure the density of smoke emitted from heavy commercial vehicles like trucks and buses, ensuring that they do not exceed pollution limits.

At the testing centre, the following procedure is typically followed:
- Inspection of Vehicle: The actual inspection of the vehicle will be done to confirm the proper functioning of the exhaust system.
- Emission measuring: The emission test will actually be done using a special machine that measures pollution emission from the exhaust. The testing will include different rates of RPM while running the vehicle engine to check emissions at various speeds.
- Analysis of Test Result: The results are then analysed to determine whether the vehicle meets the pollution control norms. According to the findings, the car will pass the emissions test if conforming to acceptable limits.
- Issuing PUC Certificate: If you pass the test, you will be provided a PUC certificate. The certificate will carry information on the test date and results as well as its validity duration (usually 6 months or one year).
