English to Spanish Tech/Engineering Construction / Civil Engineering

La traducción es sobre un sistema de ferrocarril para Chile y la oración dice:

Exceptions include the parameter that exceeded the threshold, over-the-threshold value, posted and met class of track, location of exception on tangent, spiral or curve, and the length of the exception


Le pregunté al cliente que era "posted and met class" y esto es lo que me contestó:


“Each track is rated based on the quality of the track as to the maximum speed permitted
on that track. This rating is defined as a class of track. The higher the class the higher the
speed that is permitted. The “posted class” is the rating or class that the track is rated at.
The “class met” is the class that the track would be rated at based on the results of our
current test.”


Me gustaría que me ayudarán por si saben si existe una traducción específica. Por el momento tengo "clase registrada y cumplida", pero es un invento y estoy perdida en esto. Gracias mil por la ayuda que me puedan dar.
