4. Summary of Test Method
4.1The specimen is finished to a clean, uniform surface and then irradiated by high energy X-ray photons. Secondary X- rays
are produced and emitted from the sample. This radiation is diffracted by means of analyzing crystals and focused on a detector
which measures the count rates at specified wavelengths. The outputs of the detectors in voltage pulses are integrated or counted.
Radiation measurements are made based on the time required to reach a fixed number of counts, or on the total counts obtained
for a fixed time (generally expressed in counts per unit time). Concentrations of the elements are determined by relating the
measured radiation of unknown samples to calibration curves prepared using reference materials of known compositions.
