TUBE STANDARDS

Can someone through some light on from where the concept of calibration standards for tubes/pipes has come from in which notch dimentions are defined by percentage of wall thickness.
Does it come from some kind of studies/papers on this subject i.e. what is the origin and reason for this approach.

Regards
Sunny

it is the best representation(easiest to make) of a non spherical indication. this also shows sensitivity(% of wall)
