BS EN 12680-1 is the first part of an international multi-series standard that covers the best practices for testing steel castings and products.
BS EN 12680-1 specifies the requirements for the ultrasonic examination of steel castings (with ferritic structure) for general purposes and the methods for determining internal discontinuities by the pulse-echo technique.
BS EN 12680-1 applies to the ultrasonic examination of steel castings which have usually received a grain refining heat treatment and which have wall thicknesses up to and including 600 mm.
Note 1: For greater wall thicknesses, special agreements apply with respect to test procedure and recording levels.
Note 2: BS EN 12680-1 does not apply to austenitic steels and joint welds.
BS EN 12680-1 on Ultrasonic examination of steel castings, is relevant to:
The ultrasonic examination technique is a non-destructive methodology used to test the metals, that incorporates sound waves to detect cracks and defects in parts and materials. It can also help with investigating the thickness of metal products like pipelines etc.
BS EN 12680-1 provides information about the requirements, the maximum permissible size of discontinuities as well as personnel qualifications required for performing the ultrasonic examination of steel castings with the help of the pulse-echo technique. This helps the users to detect the internal defects of the casting in a very non-destructive way.
BS EN 12680-1 lays down the detailed information about the different tests to be performed, the types of equipment, and materials needed to perform the test, explains the test principles, and samplings, helping the users to execute the complete examination with ease.
Users of BS EN 12680-1 can follow the specifications given, in order to pick out any subsurface faults in metal castings and provide defect-free castings to the consumers.
