What is BS EN 4050-3- Reference blocks for aerospace series about?
BS EN 4050-3 is an international standard that discusses the test methods for metallic materials.
BS EN 4050-3 specifies the requirements for the manufacture, checking, and marking of the series of ultrasonic testing reference blocks containing flat bottom holes (FBH) which defines the indicated defect size to which reference is made in EN standards.
BS EN 4050-3 aids on the master test blocks, standard test blocks, materials recommended.
Who is BS EN 4050-3- Reference blocks for aerospace series for?
BS EN 4050-3 on reference blocks for aerospace series is relevant to:
- Manufacturers of reference blocks
- Manufacturers of aerospace equipment and components
- Quality assurance personnel
- Aeronautical engineers 
- Aerospace engineers 
- Aerospace and defence industries
- Manufacturers of metallic materials
- Metallurgical engineers
- Testing authorities
Why should you use BS EN 4050-3- Reference blocks for aerospace series?
A reference block shows no physical behaviour but is a parametric block that is referenced by an arbitrary number of blocks.
The application of ultrasonic testing reference blocks contains side-drilled holes (SDH) which define an indicated defect size that is agreed upon between manufacturer and end-user.
BS EN 4050-3 is applicable to the production of master and standard test blocks which are used when carrying out an ultrasonic inspection according to the requirements.
BS EN 4050-3 covers all the requirements for reference blocks to be used in aerospace applications. BS EN 4050-3 helps the users with the test methods and procedures to verify the quality of the metallic materials as well as the geometric characteristics of metallic materials.
BS EN 4050-3 creates a standardized approach for manufacturers of metallic materials to adhere to if they supply their metallic materials for use by the aerospace and defence industry.
By adopting BS EN 4050-3, manufacturers can demonstrate the reliability of metallic materials and build trust for their use throughout the aerospace supply chain.
