Surface A
Mistakes such as pores, small grooves, small warts, slight scratches and a slight discoloration that does not affect the ability to reshape and adhere to surface coatings are permitted.
Surface B
The better side must be free from defects so that the homogeneous appearance of a quality finish or an electrolytically applied coating is not impaired. The other side must at least meet the requirements of surface type A.
