The British Standards Institute (BSI) are seeking feedback related to the symbolic representation of welded joints in thermoplastics moulded components in technical drawings.
The feedback they require relates to the following processes:
• Ultrasonic welding (including spot welding)
• Vibration welding (linear and orbital)
• Spin welding
• Hot plate welding
• Infrared welding
• Laser welding
• Hot gas convection welding
The aim of this is to ensure that the quality and consistency of the joining process for a thermoplastic moulded component are maintained from initial samples through to mass production, making it necessary to define the process and the joint requirements.
The aim is to achieve this via the formal customer-supplier agreement, such as the technical product documentation (TPD) and/or the technical product specification (TPS), which can include 2D drawings or 3D CAD data, such as to BS ISO 16792.
This standard defines the rules to be applied for symbolic representation of thermal joining processes for polymer components, in TPSs and TPDs. This can include information about the joining process, geometry and quality of the joint. The standard is intended to be applied for the equivalent purpose, as with BS EN ISO 2553 for metallic welded joints.
The BSI are now seeking comments about the importance of this standard for industry, which should prove to benefit any company that designs or uses design drawings of welded plastic components, especially in the automotive industry.
The deadline for your feedback to the BSI is 6 January 2026. You can provide your feedback here:
