DIN 50602 comparison charts for inclusion rating As a simplified inclusion area rating per field of view size (microscope) is normally used, no subdivision into thin/fine, heavy/thick, and large single D inclusions is required. However, since humans have trouble to judge areas by eye, in the DIN 50602 a visual aid comparison chart is available.

This is represented by columns 0, 2 and 5, each on the left of a basic column, Similar considerations apply for the evaluation of thicker inclusions with twice the area. Di values serves as indlces for the “degree of purity” of the guantity of matorial submittod for testing under the conditions existing. The length of an oxidic inclusion in the case of OA inclusions is greater than that for Diin inclusions of the same width, because for a given rating number, the aroa vrrould otherwise be dlfferent.

In the cass of lo,w-carbon steels and stainless steelg with no transformation, it is necessary to take into account the special properties of such steels see subclause 5. The values obtained in the two cases should if possible be integers and for this reason rhould be rounded, if necessarY. This magnification field under observation shall be of the same size as tho referencs diagrams of plate No.

For tlre evaluation proper, the full scale diagram plate should be used; ‘il1is can be obtainod fronr Eouth Verlag Gmbll ‘ BurygrafonstraBet1″ Berlin This standard specifies a method to be applied using a metallurgical microscope and a set of standard diagrams arranged in a systematic sequence, which enables the micrograph to be described on the basis of the type and size of inclusion length and width or diameter and the frequency standard diagram plate The factors obtained on the basis of the Zn-a goometlic series for tho other rating numbers are to be rounded so that, in the calculatlon, it is only necessaryr to double or halve the numbers.

Since such inclusions usr. For obssrvation of very thin inclusions, it is advisable to use a magniflcation of x It is not permittod to give fractions to indicate the inclusion rating e.

This figura can be used especially for simplo reading of interpolated values of inclusion length and Diagram plate No. For calculation of the total indices the procoduro is as follows see also examples glven in tables?

The relevant numbers indicate the amount by which the rating number assigned to the total length, is to be reduced because of the greater degree of fragmentation see subclause 7.
