Description

ISC Objectives

In-Service Compliance is a mandatory statutory requirement for vehicle manufacturers.

The legislator stipulates that exhaust aftertreatment systems must maintain a sufficiently high level of efficiency throughout the vehicle's useful life to ensure compliance with statutory limits.

In addition to design-side verification via type approval and tolerance verification in production via CoP, this introduces the third element: verification throughout the in-use operational phase. Vehicles aged between 6 months and 5 years, with a mileage of 15,000 to 100,000 km, must be tested and evaluated regarding emissions and consumption / energy consumption compliance.

IUPR Objectives

In-Use Performance Ratio is also a mandatory statutory requirement for vehicle manufacturers.

The legislator stipulates that the self-diagnostic system of exhaust aftertreatment systems must remain capable of detecting potential faults throughout the vehicle's useful life. For this purpose, diagnostic cycles in the engine control unit must run completely at a specified rate (relative to engine start operations – "key cycles") and yield a positive diagnostic result at a specified rate.

In addition to design-side verification via type approval (including OBD detection of aged and defective exhaust aftertreatment components) and tolerance verification in production via CoP, this adds the third element: verification throughout the in-use operational phase. Vehicles aged between 6 months and 5 years, with a mileage of 15,000 to 100,000 km, must demonstrably satisfy the IUPR criteria.
