Table 3 and Table 4 are to be used in conjunction with Tolerance Table 6 and Table 5, respectively. When Test Method B is used to measure these types of coatings, the measuring instrument shall be calibrated with thickness standards that have the same substrate and same composition of coating as the product.
The diffusion is slow at room temperature and rapid at elevated temperatures. A thicker coating of nickel may be required in some situations for additional retardation. Government Packaging Requirements S4. The amount of porosity in the coating that may be tolerable depends on the severity of the environment that the article is likely to encounter during service or storage. However, all matte baths except for stannate baths do require the addition of grainre?
