Summary概述
In order to be able to compare the results obtained by different railways, both as to 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.
为了比较不同铁路的结果，一方面关于等效锥度，另一方面关于等效锥度起重要作用时的试验结果，有必要依据同样的原理计算等效锥度
This leaflet sets down the principles of calculation that must be followed, but it does not impose any particular numerical calculation method.
本标准制定了必须遵循的计算原理，但没有强制采用任何特定的数值计算方法。
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.
本标准说明了进行测量时的误差范围，此外提供了参考外形，以及使用程序和考虑测量系统引入的最大测量误差，等效锥度计算结果必须满足的容许系列。
