BS EN 10049 defines the measurement conditions for surface roughness parameters of metallic flat products, both uncoated (cold and hot rolled pickled steel) and coated with metallic coatings (e.g. zinc, aluminium, tin, chromium).
BS EN 10049 provides a set of guidelines of measurement of roughness average Ra and peak count RPc on metallic flat products.
BS EN 10049 consists of specification for measuring the roughness average and consists of the measurement equipment used, evaluation profile filter, pickup system, sample preparation, checking the measuring instrument, measuring conditions, disputes, etc.
BS EN 10049 on Ra and peak count RPc on metallic flat products is useful for:
Surface roughness is an important part of finishing a product. It helps to determine how the product and the metal will react with the environment. Irregularities prevent corrosion and act as a nucleation site for cracks. Therefore, it is an indicator of the potential of the product and its performance.
BS EN 10049 is a set of guidelines for the engineers and manufacturers to measure the roughness of Ra and peak count RPc on metallic flat products as a part of surface texture. Since it helps to prevent corrosion, it is an important aspect covered by the manufacturers.
BS EN 10049 guidelines help the users to enjoy a long-lasting and corrosion-free product that does not react in the environment and holds its good quality for a long period of time.
