What is EN ISO 13920:2018?

EN ISO 13920:2018 is an international standard that provides guidelines for the tolerance of welded, brazed, and soldered constructions. It specifies the general principles to be followed when determining the dimensions and geometrical tolerances of workpieces.

Importance of EN ISO 13920:2018

The standard plays a crucial role in ensuring the quality and reliability of welded constructions. By establishing clear guidelines for dimensional accuracy and tolerances, it helps to minimize errors and inconsistencies in manufacturing processes. This not only enhances the safety and performance of the finished products but also increases customer satisfaction by delivering reliable and consistent results.

Key Features and Guidelines

EN ISO 13920:2018 covers various aspects of dimensional control and tolerances related to welded constructions. Some of the key features and guidelines include:

Tolerances for linear dimensions: The standard provides tolerance limits for length, width, and depth measurements. These limits ensure that the final dimensions of the workpiece fall within an acceptable range specified by the standard.

Tolerances for angular dimensions: EN ISO 13920:2018 also defines tolerance limits for angles and inclinations. This helps to maintain the desired angle between different components and ensures proper alignment and fit.

Geometrical tolerances: The standard covers various geometrical parameters such as flatness, straightness, symmetry, and position. It provides guidelines for measuring and specifying these parameters accurately, allowing manufacturers to maintain the required shape and form of the workpiece.

Tolerances for surface conditions: EN ISO 13920:2018 also addresses surface imperfections such as dents, scratches, and roughness. It specifies acceptable limits for these defects to ensure a smooth and functional surface finish.

Conclusion

EN ISO 13920:2018 is an important standard that sets guidelines for tolerances in welded, brazed, and soldered constructions. By adhering to this standard, manufacturers can achieve dimensional accuracy, improve product quality, and enhance customer satisfaction. Compliance with EN ISO 13920:2018 ensures that the finished products meet the desired specifications and perform reliably in their intended applications.
