What is BS EN 1670:2020?

BS EN 1670:2020 is an important standard in the construction industry that specifically addresses the performance requirements and testing methods for corrosion resistance on architectural ironmongery. This article aims to provide a comprehensive overview of this standard, exploring its key components and significance.

Definition and Scope

BS EN 1670:2020, titled "Building hardware: Corrosion resistance: Requirements and test methods", is a European standard that sets guidelines for evaluating the durability and corrosion resistance of ironmongery products used in the construction of buildings. The standard primarily applies to door and window fittings, such as hinges, locks, handles, and bolts.

Corrosion resistance is a critical factor in determining the longevity and effectiveness of architectural ironmongery. Without proper protection, these components can deteriorate over time, compromising their functionality and jeopardizing building security. Therefore, BS EN 1670:2020 plays a crucial role in ensuring the reliability and performance of ironmongery products.

Key Requirements and Testing Methods

BS EN 1670:2020 outlines specific requirements that architectural ironmongery must meet in terms of corrosion resistance. These requirements are categorized into different classes, ranging from Class 1 to Class 5, with each class representing a different level of performance.

To assess the corrosion resistance of ironmongery products, various testing methods are employed. These methods simulate real-life environmental conditions and evaluate the product's ability to withstand corrosion. Some of the common tests include salt spray testing, humidity testing, and acid mist testing.

Additionally, the standard provides guidelines for conducting accelerated corrosion tests and determining the potential for galvanic corrosion when dissimilar metals come into contact.

Significance and Benefits

BS EN 1670:2020 is significant not only for manufacturers and suppliers of architectural ironmongery but also for specifiers, architects, and builders. Compliance with this standard ensures that the products meet industry-recognized quality benchmarks and are capable of withstanding harsh environmental conditions.

By adhering to BS EN 1670:2020, contractors can minimize the risk of premature failure and costly replacements of corroded components. This, in turn, enhances the overall lifespan and durability of the constructed building.

Furthermore, the standard promotes consumer confidence as it provides assurance that the architectural ironmongery used in buildings meets rigorous corrosion resistance criteria.

In conclusion, BS EN 1670:2020 plays a vital role in enhancing the performance and longevity of architectural ironmongery. By establishing requirements and testing methods, it ensures that these products resist corrosion and maintain their functionality over time. Adhering to this standard equips the construction industry with high-quality, reliable ironmongery, providing long-lasting and secure buildings.
