Normative annexes provide:

this Technical Specification identifies the mathematical formulae for rigorously constructing Physical Sensor Models that relate two-dimensional image space to three-dimensional ground space and the calculation of the associated propagated error

This International Standard specifies a method for the determination of the niobium content in steel by means of inductively coupled plasma emission spectrometry

For samples for chemical analysis reference is made to EN 14361

It is applicable for the measurement of samples with a mass fraction of chlorine from 5 µg/g to 500 µg/g and with a mass fraction of fluorine from 2 µg/g to 500 µg/g
