It is logical to conclude that dynamometer tests will be designed using the ECE90 and  VC8053 specifications as a guide. These specifications are specific about the required testing and go as far as to supply the pressures, speeds, temperatures and torque’s required to do the testing.

A modern brake test Dynamometer uses an absorption unit, in this case a brake disk and calliper assembly, to dissipate or convert the power or kinetic energy into heat or thermal energy. The power used to do this is calculated as follows:

To the knowledge of the writer the word "Dynamometer is probably derived from the unit "dyne". One Dyne is the force required to cause a mass of one gram to accelerate at a rate of one centimetre per second per second in the absence of other force-producing effects. [1] This unit is rarely used today and is discouraged in favour of the Newton (N) that is part of the SI system.
