EN 10049 RPC Measurement Test for Roughness Average Ra and Number of Peaks in Metallic Flat Products

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of EN 10049 testing. This European standard 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, aluminum, tin, chrome).

The tool to be used is a stylus tool or an optical roughness measurement system in accordance with EN ISO 3274. The device generally consists of a measuring head, a traverse unit and an evaluation device. When using an optical roughness measurement system, calibration should ensure that the measured values ​​align with the reference stylus method values.

The samples must be flat, ie the maximum degree of bending should not exceed 200 mm over a length of 4 mm. It must be clean and free of any features or other defects that could impair the roughness measurement. It must be degreased before measurement. Samples for measurement should be taken at least 40 mm from the edge of the surface to be checked.

The roughness average Ra is a measurement used to measure the amount of roughness on the surfaces of metallic flat products. The Ra value measures the distance between the highest and lowest points on the surface of the product. The measurement measures the distance between the highest and lowest points on the surface of the product.

Peak number RPC (Roughness Profile Count) is another metric used to measure the amount of roughness on the surfaces of metallic flat products. The RPC value measures the number of peaks present on the surface of the product. The measurement measures the number of peaks present on the surface of the product.

These two measurements are used to measure the amount of roughness on the surfaces of metallic flat products. These measurements show the amount of roughness on the surface of the product and are used to evaluate the surface quality of the products.
