Emission testing is a more comprehensive test that measures the pollutants emitted by a vehicle. It includes testing for carbon monoxide, hydrocarbons, nitrogen oxide, and particulate matter. POLLUTION CHECK SYSTEM Emission testing In 1966, the first emission test cycle was enacted in the State of California measuring tailpipe emissions in PPM (parts per million). TÜV SÜD offers vehicle emissions testing solutions for compliance with global standards and regulations, such as WLTP, RDE, China 5 and 6, and CO2. Learn about the benefits, methods, and challenges of emissions testing and how TÜV SÜD can support you. During this examination, experts measure the levels of harmful gases like Carbon Monoxide (CO) and other hydrocarbons in parts per million (PPM), according to specific standards. If the bike meets these standards, the owner gets a Pollution Under Control (PUC) certificate.
