APL has state-of-the-art roller testing centers at its locations in Landau and Bietigheim-Bissingen, which are suitable for a wide range of testing tasks in the passenger car and light-duty sectors. Certifications according to ISO 9001 and accreditation by DAkkS according to DIN EN ISO/IEC 17025 ensure stable processes and ensure the highest data quality.

In addition to the worldwide legally required exhaust gas cycles, taking into account the respective prescribed boundary conditions, it is possible to display customer-specific driving programs (e.g. simulation of RDE driving, R2R, etc.) on the high-performance rollers. In conjunction with needs-based temperature conditioning (up to -35 °C) of both the test bench and the test object, you as a customer are guaranteed absolutely reliable transferability of the road measurement.

In addition, our roller dynamometers are equipped with extensive exhaust gas measurement technology, which enables the exhaust gas components to be determined not only in the diluted exhaust gas, but also in the raw exhaust gas at any point in the exhaust system.

Services we provide for you:

Preparation and follow-up of the vehicles for roll operation

• Equipment of the vehicle with test parts: engine and exhaust system
• Production of exhaust gas adaptations
• Assembly/disassembly of tires, adaptations, suspension components, etc.

TISAX-compliant prototype protection

Role testing

• for a wide range of drivetrain configurations (2WD, 4WD)
• for current and future-oriented drive concepts (VKM, hybrids of all kinds, e‑traction)
• according to global legal requirements (EU, EPA, CARB, China etc.)
• for simulating road driving (RDE etc.)

Execution of control device data, emissions and accompanying certification

• UN ECE R83
• VO (EU) 2017/1151

COP review

• UN ECE R83
• VO (EU) 2017/1151

Support development activities with special exhaust gas measurement technology in raw exhaust gas (particle counter, soot sensor, FTIR, etc.)

Our testing laboratories therefore offer the best conditions to support you in your development and certification activities with the highest quality, reliability and efficiency.

APL modernized its measuring room at its Landau location last year and equipped it with the latest technology. According to VDI guideline 2627, it corresponds to a fine measuring room of quality class 2. Our high quality awareness is reflected in the fact that experienced project engineers control our projects; technical know-how in relation to the handling of the parts to be measured is required here.

But what does that mean?

• Temperature control of the components before measurement in the preconditioning room
• Control and monitoring of temperature and humidity
• Intercepting and dampening vibrations
• Prototype protection: access control to the measuring room
• Extensive experience in geometric measurement technology for the automotive industry

Our measurement tasks include:

• Geometry measurement
• Topography measurement
• Wave measurement
• Roughness measurement
• Contour measurement
• Weight measurement
• Warpage and wear measurement
• Labeling with laser device
• Spring force measurement
• Tangential force measurement
• Timing chain measurement
• Endoscopy
• Laser scanning microscopy

By the way: We don’t just work for the automotive industry. We welcome all sectors.
