1) For special applications requiring fine-grained castings, the ingots may be ordered and supplied grain refined to a maximum average grain
diameter of 0,150 mm
2) For drinking water applications no other single element should be more than 0,02 %. The sum of these single elements should not exceed
0,25%.
3) In castings for non drinking ater applications, Sb can be used as alternative inhibitor of dezincification. If Sb is added as the inhibitor, then
the inhibitor, then the As content shall be 0,04% maximum. (Sb+As) shall be 0,14% maximum.
4) For drinking water applications, Sb shall ≤ 0,02%.

Unless it is agreed between the purchaser and the supplier that other grain refining agents may be used, ingots in this alloy
shall be grain refined using boron, to have a maximum average grain diameter of 0,100 mm.
