What is ISO 6508-1- Metallic materials- Rockwell hardness test about?
ISO 6508-1 is a safety standard on metallic materials.
ISO 6508-1 specifies the method for Rockwell regular and Rockwell superficial hardness tests for scales A, B, C, D, E, F, G, H, K, 15N, 30N, 45N, 15T, 30T, and 45T for metallic materials and is applicable to stationary and portable hardness testing machines.
For specific materials and/or products, other specific International Standards apply (for instance, ISO 3738-1 and ISO 4498).
Note: Attention is drawn to the fact that the use of tungsten carbide composite for ball indenters is the standard type of Rockwell indenter ball. Steel indenter balls are allowed to continue to be used only when complying with Annex A.
Who is ISO 6508-1- Metallic materials- Rockwell hardness test for?
ISO 6508-1 on Rockwell hardness test for metallic materials is relevant to:
- Manufacturers of Rockwell hardness tester and scale
- Testing authorities for metallic materials
- Corrosion engineers
Why should you use ISO 6508-1- Metallic materials- Rockwell hardness test?
Rockwell hardness testing is a method used to measure the hardness of metallic materials.
ISO 6508-1 assist with the test that is carried out on a surface that is smooth and even, free from oxide scale, foreign matter, and completely free from lubricants unless specified otherwise in product or materials standards. Preparation is carried out in such a way that any alteration of the surface hardness due to excessive heating or cold-working for example, is minimized. ISO 6508-1 has been developed with a laboratory temperature requirement of 10 °C to 35 °C. This test is applicable to thin sheet metal products having a maximum thickness of 0,6 mm to the minimum thickness indicated in the product standards, and of a maximum hardness of 82 HR30TSm or 93 HR15TSm.
Overall, ISO 6508-1 is useful as it provides guidance on the Rockwell hardness test for metallic materials which help in measuring the hardness of metallic materials.
