Summary:
ry
In order to be able to compare the results obtained by different railways, both as to the value of the equivalent conicity and as to the test results where this parameter plays an important role, it is necessary for the equivalent conicity to be calculated according to the same principles.
This leaflet sets down the principles of calculation that must be followed, but it does not impose any particular numerical calculation method.
It states the tolerances within which the measurements should generally be made, and beyond that it provides reference profiles and a range of acceptability within which the results of the conicity calculation must fit using the program and taking into account the maximum random errors introduced by the measuring system.
