What is BS EN 16090 about?
BS EN 16090 is a safety standard on copper and copper alloys.
BS EN 16090 specifies a method for the estimation of the average grain size of copper and copper alloy products by ultrasound.
BS EN 16090 is applied for seamless round tubes as well as for flat products.
Note: When using this test by ultrasound technique, it is important to recognize that the estimation of grain size is not a precise measurement because a metal structure is an aggregate of three-dimensional crystals of varying sizes and shapes. Clearly, no two areas of observation can then be exactly the same.
Who is BS EN 16090 for?
BS EN 16090 on estimating average grain size by ultrasound is relevant to:
- Copper industries
- Corrosion engineers
- Thermal engineers
- Hardware and automotive industries
- Metallurgical engineers
- Mechanical engineers
- Operators trained in ultrasound testing
Why should you use BS EN 16090?
Copper alloys are metal alloys that have copper as their principal component.
BS EN 16090 describes the test by ultrasound which has the objective of estimating the dimension of average grain size in copper and copper alloy products. Ultrasonic testing is a comparative method, calibrations for every alloy or group of alloys (calibration graph) considering the thickness.
Overall, BS EN 16090 is useful as it guides the ultrasonic testing and results analysis which typically is done in an automated system against pre-determined criteria without human intervention.
