This document specifies methods for sample preparation to ensure representativeness of the samples throughout the preparation procedures to produce general analysis samples. Suitable test portions can be taken from the laboratory or general analysis samples and used for analysis according to the specific requirements defined in the corresponding analytical procedures.
This document specifies the correct sample preparation sequence to be applied to: a) the composite sample, in order to produce a laboratory sample (taking into account large pieces of solid recovered fuel);
b) each sub-sampling step throughout the testing programme;
c) the laboratory sample, in order to obtain suitable test portions;
d) ensure the representativeness of the test portions that have been taken according to the sample preparation plan, prior to physical analysis, chemical analysis or both (e.g. extractions, digestion, analytical determinations).
