Procedure for certifying the conformity of construction machines and their particle filter systems with the requirements of the Swiss Federal Ordinance on Air Pollution Control (OAPC)

Procedure for certification of conformity: The diagram on the left depicts the complete procedure for certifying the conformity of construction machines and their particle filter systems with the OAPC (Article 19b), together with the involved offices and authorities.
The addresses and contact details of accredited and recognised testing laboratories and certification bureaux are indicated below.
At the request of the manufacturer or importer, a testing laboratory accredited and recognised by the FOEN verifies the conformity of the filter system with the OAPC based on SNR standard 277205 (Case B: particle filter system for retrofit, so called Retrofit). For construction machines, whose engines and their particle reduction systems are type-approved according to directive 97/68/EC (so called OEM machines), the respect of the particle number limit of the OAPC has to be proved (Case A). The laboratory then issues a test report which has to be submitted to an accredited and recognised certification bureau together with an application for certification of conformity. The certification bureau verifies the conformity of the particle filter system and the OEM machine respectively and issues a certificate of conformity to the applicant, who in turn issues a declaration of conformity in accordance with Article 19b, Paragraph 1b of the OAPC.
The manufacturer or importer is required to retain this declaration of conformity for a period of 10 years from the date on which the construction machine or particle filter system was first brought onto the market. The declaration of conformity must also be available on site so that it can be presented in the event of an inspection of the construction machine. The FOEN will add the filter system concerned to the FOEN Filter List as soon as it receives a copy of the certificate of conformity issued by the certification bureau (Case B only).
