Over deze norm
Melts of aluminium alloys are susceptible to segregation when solidifying. Cast products, therefore, have concentration gradients. Axial and radial segregation profiles affect the representative sampling from melts, cast products or laboratory samples. In the case of direct measurement of on solid samples (e.g. spark optical emission spectrometric analysis S-OES) measuring signals are influenced by the morphology of solidification and cast structure of the sample. This standard provides requirements which ensure the correspondence between the average chemical composition of the cast to be tested and the average chemical composition of the test portion.
