What is BS EN 14728- Classifying imperfections in thermoplastic welds about?
BS EN 14728 is a European Standard that discusses imperfections in thermoplastic welds. It aims to enhance defect detection in welds for improved quality and performance.
BS EN 14728 specifies a system for classifying imperfections that may be encountered in thermoplastic welded joints during manufacture and provides examples of imperfections for the
- Heated tool butt welding
- Heated tool socket welding
- Electrofusion socket welding
- Hot gas welding
- Extrusion welding
- Solvent socket welding
BS EN 14728 can be used in conjunction with EN 16296 to determine the acceptance of welds.
Note: BS EN 14728 does not describe imperfections that may be generated during service or imperfections present before welding, which is due to poor preparation or assembly of components.
Note: BS EN 14728 does not apply to the search for the possible influence of these imperfections on the behaviour of joints in relation to the different types of stress to which the latter may be subjected or on methods for preventing such imperfections.
Who is BS EN 14728- Classifying imperfections in thermoplastic welds for?
BS EN 14728 on classifying imperfections in thermoplastic welds is applicable to:
- Manufacturers and suppliers of thermoplastic polymers
- Automotive industry
- Medical packaging industry
- Electronic packaging industry
- Plastics industry
Why should you use BS EN 14728-Classifying imperfections in thermoplastic welds?
Thermoplastic welding is a process used for joining pieces of thermoplastic material using heating, pressure, and cooling. Since the thermoplastic material is heated to its melting point, there are many chances of imperfections in thermoplastic welded joints.
Guidelines in BS EN 14728 helps you in finding possible origin or causes of the imperfections and provides the standardized classification of imperfections in thermoplastic welded joints.
You can adopt BS EN 14728-compliant classification for better identification of defects that can aid in improving the quality and reliability of thermoplastic welded joints.
What’s changed since the last update?
BS EN 14728:2019 supersedes BS EN 14728:2005, which is withdrawn. Includes some technical changes these are:
- Clause 3, Symbols, and designations has been deleted
- Examples of imperfections for the different welding processes are in Tables 1 to 6
