Evaluation Procedure for Aftermarket Diesel Particulate Filters for On-Road Heavy-Duty Diesel Engines
The California Evaluation Procedure for New Aftermarket Diesel Particulate Filters Intended as Modified Parts for 2007 Through 2009 Model Year On-Road Heavy-Duty Diesel Engines (Evaluation Procedure) was adopted by CARB on March 1, 2017. The purpose of the Evaluation Procedure is to ensure that owners of diesel engines who need to replace their original diesel particulate filter (DPF) have an option other than purchasing it only from the original engine manufacturer (OEM). This evaluation ensures that the aftermarket DPF reduces particulate matter the same as the OEM filter and is durable, as well as compatible, with various engines and applications. All applicants should be aware that as part of the evaluation process, it is the applicant’s responsibility to provide data which satisfies CARB that their aftermarket DPF meets all requirements necessary to be approved. This includes but is not limited to: laboratory testing, in-use testing, annual warranty reporting and any other criteria which CARB deems appropriate for complete evaluation of the aftermarket product.
