last sample in a series of repetitive samples producing a result that in less than 10 % of all the samples

X-ray detection system with which energy dispersive X-ray spectra are recorded for element analysis

operation required to transfer as many as possible of the contaminants present in a controlled volume or on the controlled surface of a component into a known volume of test liquid for a subsequent analysis

progress curve of the cleanliness level of an extraction liquid applied to the test component in relation to extraction time or volume of test liquid passed through or over the test component, depending
on the type of liquid and test conditions (e.g. flowrate, pressure)

test liquid once loaded by contaminants extracted from the test component

method defining all the necessary parameters to transfer contaminants from either the controlled surface or the control volume of a component into the test liquid, making the operation reproducible

test sample total amount of liquid to be analysed present in one or a number of sample containers carrying the contaminants extracted from a component

total volume of liquid used to extract the contaminants from a component
