product details / scope of delivery


  • Transient emission testing for accurate analysis and measurement of emissions for vehicles under load (in conjunction with MAHA emission testers)
  • Driving resistance simulation for ASM-5015 and ASM-2525 emission tests (Acceleration Simulation Mode) in line with the BAR '97 specifications

Roller Set Description and Standard Delivery

  • Self-supporting closed roller set frame
  • In-ground installation Foundation required for in-ground installation
  • Electric eddy-current brake with separate flywheel
  • AC-Motor including control and power electronics
  • Foundation cover plate
  • Varnished with high-quality powder coating: Anthracite Grey, RAL 7016 (frame) Ruby Re , RAL 3003 (rollers)

Operating modes of the tester in conjunction with emissions
analyser or external PC:

  • Driving resistance simulation for ASM-5015 and ASM-2525 emission tests (Acceleration Simulation Mode) in line with BAR '97 specifications
  • Driving resistance simulation for transient emissions testing in line with standard test cycles (note: vehicle inertia simulation in deceleration mode limited to 2000 lbs (900 kg)
  • Determination and compensation of equipment's own losses (‘Parasitic losses’) according to BAR '97 specifications. Acceleration of the roller set with built-in AC-Motor to approx. 50 km/h with subsequent performance of roll-off tests (‘coast-down’).
  • Performance measurement (wheel power) possible in the operation modes:
    • constant speed
    • constant tractive force
  • Control of equipment via serial interface RS232 (e.g. emissions analyser which meets ‘BAR '97’ specifications or external PC)
