Weight of the ingot shall be not more than 3.5 kg.

Allowed by agreement between manufacturer and consumer, the production of palladium bullion with other dimensions and mass.

1.2, 1.3. (Changed edition, Rev. N 2).

1.4. The surface of ingots shall be clean and processed by cutting or grinding.

Foreign inclusions are not allowed.

The surface roughness should be not more than 80 µm according to GOST 2789.

Allowed Stripping of individual surface damage. The depth of the denuded areas on the surface of ingots shall not exceed 1 mm.

(Changed edition, Rev. N 1).
