Grading systems by country - Wikipedia

Grading scales can be 1 to 7, 1 to 5, or A through F, where A is on a 4.0 scale or on a 5.0 scale. The most common scale is now 1 to 5, with 5 being the highest grade obtained. In addition, degrees are awarded in a Class, depending on the grades received. Degrees may be awarded in the First Class, Second Class (Upper Division), Second Class (Lower Division), Third Class and Pass Class. Grading ...

A Detailed Guide on Grading of Aggregates.

Grading of aggregates is determining the average grain size of the aggregates before they are used in construction. This is applied to both coarse and fine aggregates. The aggregate sample is sieved through a set of sieves and weights retained on each sieve in percentage terms are summed up. On dividing this sum by 100, The Fineness Modulus of that aggregate is determined. This helps in ...

European Aggregate Sizes - Northstone Materials

To complicate matters more, for fine and all-in aggregate, where D <= 8mm, the standard requires producers to declare a "typical grading", which, where required, must be within a given Tolerance Category designated according to a set ± value on the D/2 sieve, i.e., G TC 10, G TC 20 or G TC NR (no requirement). A typical quarry dust could be designated 0/4 G A 85 G TC 20.
