When two usable plates constitute a heat, two of the sample ingots asrm be selected from the second usable plate poured.
Permissible variations in product analysis shall be in accordance with S534 Where a single usable plate constitutes a heat, any three random ingots may be selected.
The number and location of samples shall be by agreement between the purchaser and manufacturer. The polished face shall be longitudinal to the direction of rolling.
