PEMS – exhaust emissions testing under real driving conditions for light duty and heavy duty vehicles

PEMS – testing exhaust emissions from Light Duty Vehicles (LDV) and Heavy Duty Vehicles (HDV) under real driving conditions and from Non-Road Mobile Machinery (NRMM) under actual operating conditions

Emission testing of vehicles and non-road mobile machinery under real driving / actual operating conditions using Portable Emission Measurement Systems (PEMS):

Light Duty Vehicles (passenger cars and light commercial vehicles) – Real Driving Emission testing (RDE) – Type approval (TA) and In-Service Conformity (ISC)

Heavy Duty Vehicles (trucks, buses, etc.) – Real Driving Emission testing – Type approval (TA) and In-Service Conformity (ISC)

Non-road mobile machinery – Actual machinery operation – In-service monitoring (ISM)

Non-Road Mobile Machinery emission testing using Portable Emission Measurement Systems (PEMS) – In-service emission testing – In-Service Monitoring (ISM)

Operation requirements:

Measurement is based on the concept of working and non-working operating events
Emission testing to be performed on engines (Stage V) installed in non-road mobile machinery:
Category: NRE, NRG, NRS, IWP, IWA, RLL, RLR, ATS, SMB
Procedure to determine working and non-working operating events:
Only working events are used for calculations of gaseous pollutant emissions and conformity factors	Any event considered as a non-working event aren’t taken into account for emission calculations
Non-working events shall be categorised as:
Short non-working events ≤ D2	Long non-working events > D2
Non-working events:
Engine power < 10% of the engine maximum net power	Cold start
Ambient conditions not fulfilling the requirements	Checks of the measurement instruments
