The aim of market surveillance is to ensure compliance with emission limits for internal combustion engines in mobile equipment and machinery and to protect against unfair competitive practices. This applies to gardening equipment, DIY equipment, construction machinery, leisure equipment and model sports.
The immission control is affected, as the monitoring or control is about the compliance with air pollutants such as unburned hydrocarbons, nitrogen oxides, soot and dust.
Compliance with engine emission levels in mobile machinery is essential. Non-compliant engines or the machines in which they are installed must not be placed on the market.
In addition to the active role of the authorities, the EU Market Surveillance Regulation and the national Market Surveillance Act also provide for the possibility of reporting non-compliant engines by citizens, non-governmental organizations and other bodies under public law. These can report their knowledge of suspected non-conformity to the body responsible for market surveillance. For the whole of Bavaria, this is the Government of Lower Bavaria. There is no specific formal requirement for this notification.
The distributor and manufacturer of the device must be named and, if applicable, the emission problems associated with this device.
