On 19 September 2008, the Swiss Federal Council amended the Ordinance on Air Pollution Control (OAPC). Construction machines with an output higher than 18 kW either have to comply with a specified maximum level of particle emissions or be equipped with a particle filter system that meets the requirements of the OAPC.

These regulations apply to all construction machines manufactured after 2010 with an output between 18 and 37 kW. With effect from 1 May 2015, they will also apply to construction machines that were manufactured prior to 200 and have an output higher than 37 kW.

The FOEN Filter List contains a list of particle filter system types, plus a separate list of engine types, that meet the requirements of the Swiss Federal Ordinance on Air Pollution Control (OAPC) and have been certified by a recognised certification bureau. Institutions that carry out tests and certify the conformity of particle filter systems must be accredited by their national accreditation authority and officially recognised by the FOEN.

The level of particle emissions is calculated in accordance with the UN/ECE particle measurement programme. The testing procedure specified in the OAPC for particle filter systems is based on Swiss standard SN 277206 - an official standard of the Swiss Association for Standardisation (SNV). The SN 277206 replaces Swiss standard SNR 277205.

The recognition of particle filter system types that meet the requirements of the OAPC is based on a certification procedure that comprises a test of the filter type and certification of conformity based on the test report. The certification bureau concerned then issues a declaration of conformity to the manufacturer, who in turn provides the buyer with a declaration of conformity. The testing centre and certification bureau concerned have to be accredited and officially recognised by the FOEN.
