This specification covers double-reduced electrolytic tin plate produced from low-carbon cold-reduced steel furnished in coils and cut sizes for use predominately in the manufacture of cans. Double-reduced plate is relatively brittle and has very distinct directional properties. The rolling direction shall be specified on cut sizes and will be indicated by underlining the slit (rolling width) dimension. In sampling for tin coating weights [masses], the following procedure shall be used: a test strip shall be taken at random from a representative section of each coil across its width; from one or two coil lots, each coil shall be sampled; and a sheet shall be taken at random from each packages, each taken from different bundles from any one item of a specific shipment. X-ray fluorescence method shall be performed to determine the tin coating weight. Surface appearance shall be bright or matte depending on coating processes and the base metal finish shall have a smooth finish with grit lines. Chemical treatments for tin plate shall be cathodic sodium dichromate (CDC) treatment or sodium dichromate dip (SDCD/SDD) treatment. Electrolytic tin plate is furnished with an oil film applied to both surfaces.
