Galvanized Color Coated Coil-Tinplate Testing
The tests which may be applied to tinplate can broadly be classified into two groups, objective, or quality tests and subjective, or performance tests. Many of these tests, especially the former, are routinely carried out during manufacture, as part of a quality control programme. Other, more sophisticated tests are used for research purposes or to investigate problems which may have arisen in service. The validity of any testing procedure is based on the assumption that the samples selected are representative of the bulk of the material to be tested. Sampling procedures for selecting sheets for mechanical property and coating thickness tests are outlined in the international and national standards.
