EN ISO 13920-B:2018 is a professional technical standard that defines the requirements for geometric tolerancing and dimensional accuracy in welding. It is part of the larger ISO 13920 series, which covers different aspects of welding, including welding symbols, welding terminology, and graphical symbols for welds.
Scope of EN ISO 13920-B:2018
This standard specifically focuses on the requirements for linear dimensions and angles in welded structures. It provides guidelines for specifying and obtaining an appropriate level of dimensional accuracy in welded products, helping to ensure consistent quality and fit between different components.
Main Principles of EN ISO 13920-B:2018
EN ISO 13920-B:2018 outlines several key principles that underpin the dimensional accuracy in welding. These include:
Tolerance Categories: The standard introduces four tolerance categories (I, II, III, and IV) to classify the required level of accuracy based on the function and appearance of the welded component.
Reference Systems: It defines different reference systems and coordinate positions to determine dimensions and tolerances effectively.
Basic Dimensioning Rules: The standard provides specific rules for dimensioning and tolerancing, ensuring clarity and uniformity in specifying requirements.
Geometric Tolerances: It offers guidance on geometric tolerancing, allowing for deviations within permissible limits while maintaining functional requirements.
Inspection Methods: EN ISO 13920-B:2018 also suggests various methods for inspecting and verifying the dimensional accuracy of welded structures.
Benefits of EN ISO 13920-B:2018
Adhering to EN ISO 13920-B:2018 brings several advantages to the welding industry. Firstly, it enhances product quality by establishing clear standards for dimensional accuracy. This, in turn, ensures better fit and compatibility between welded components, reducing the risk of failures or structural issues.
Secondly, the standard promotes consistency and uniformity in product specifications, facilitating communication between manufacturers and customers. By using a common language and reference system, misunderstandings can be avoided, resulting in fewer delays and disputes.
Thirdly, complying with EN ISO 13920-B:2018 enables companies to demonstrate their commitment to quality and compliance. Businesses that meet recognized standards are more likely to gain trust and reputation in the marketplace, opening doors to new opportunities and partnerships.
In conclusion
EN ISO 13920-B:2018 is a vital technical standard that sets requirements for dimensional accuracy in welding, providing guidelines for tolerance categories, reference systems, dimensioning rules, geometric tolerances, and inspection methods. Adhering to this standard brings numerous benefits, such as improved product quality, enhanced communication, and increased market credibility.
