BS EN 3718 is a European Standard that discusses the ultrasonic inspection of tubes. The main objective of BS EN 3718 is to provide best industry test methods to enable identification of defects in metallic tubes and ensure they are fit for purpose.
BS EN 3718 specifies the requirements for ultrasonic inspection of tubes in metallic materials with an external diameter ≥ 5 mm.
In other cases, the use of BS EN 3718 is by agreement between the manufacturer and the purchaser.
The purpose of the ultrasonic inspection is the detection of defects within the wall thickness and at the outer and inner surfaces of the tube. The method will detect two-dimensional defects in the longitudinal and circumferential directions perpendicular to the tube wall. Where inspection for other types of defects is required, this requirement should be stated on the order.
BS EN 3718 on ultrasonic inspection of metallic tubes for use in aerospace is useful for:
Ultrasonic testing is a non-destructive testing method that takes advantage of high-frequency sound waves to analyze inconsistencies within materials.
BS EN 3718 walks you through the ultrasonic inspection procedure to demonstrate the flaws and defects of metallic tubes. This can be particularly beneficial for quality control purposes.
It creates a standardized approach for manufacturers of metallic tubes to adhere to if they supply their components for use by the aerospace and defence industry.
If you are a manufacturer of metallic tubes, BS EN 3718 can help you improve the quality and reliability of metallic tubes and build trust in their use throughout the aerospace supply chain.
