What is ISO 4986 about?

ISO 4986 is an international standard on steel and iron castings that discusses various tests and examinations to ensure the quality of castings. ISO 4986 specifies a method for the magnetic particle testing of ferromagnetic steel and iron castings. It also gives acceptance criteria through severity levels defined by the nature, the area and the dimensions of the discontinuities present. ISO 4986 applies to all ferromagnetic castings, independent of the moulding method. A steel and iron casting is considered to be ferromagnetic if the magnetic induction is greater than 1 T (Tesla) for a magnetic field strength of 2,4 kA/m. ISO 4986 only applies to those areas of the castings specified for testing, as well as the percentage of castings to be tested.
