The 71/320/CEE of the European Standard is assisted by Taylor Maltese. The requirement is: Downhill durability tests must be carried out for trucks with a load of over 10 tons and passengers with more than 8 passengers. Durability test requires that a passenger car (truck) with a full load on a 7% (6%) downhill ramp must not use a brake device. The passenger car can run downhill at a steady speed of 30Km/h. The continuous working time is not less than 12 minutes.
The current world-recognized retarder standard is European regulation. The requirement of this standard is a comprehensive performance requirement, which not only stipulates the output power of the retarder, but also requires retarder to ensure certain durability.
The Chinese standard JT/T721 «Car eddy current retarder loading performance requirements and test methods» is also assisted by the development of Taylor, its main: the vehicle on a flat road with a constant speed of 50Km / h, retarder alone When braking to the test vehicle 30Km/h, the deceleration (a) shall meet the requirements of 0.62m/s2≤a≤1.0m/s2, or the deceleration time (t) shall meet the requirements of 5.6s≤t≤9.0s.
The requirements of this standard are a comprehensive performance requirement, which not only stipulates the braking performance of the retarder, but also requires a retarder to guarantee certain repetition and thermal decay performance.
