Title: Which is Better: BS 476-22 or BS EN 1634-1? A Comprehensive Comparison

When it comes to fire resistance, the choice between BS 476-22 and BS EN 1634-1 is critical for professionals in the construction industry. Both standards are designed to ensure that fire-resistant doors and shutters are built to a high standard, but they differ in certain criteria. In this article, we will provide an in-depth comparison of the two standards, outlining their key differences and advantages.

BS 476-22: An Overview

BS 476-22 is a British standard that outlines the requirements for fire-resistant doors and shutters. It was first published in 1989 and has been updated several times since then. The standard is widely recognized in the construction industry and is considered a benchmark for fire-resistant doors and shutters.

BS EN 1634-1: The European Standard

BS EN 1634-1 is an European standard that outlines the requirements for fire-resistant building materials, including doors and shutters. It was first published in 2008 and has been updated several times since then. The standard is designed to ensure that European building materials meet the same high standards as those in the BS 476-22 standard.

Key Differences:

Origin: BS 476-22 is an American standard, while BS EN 1634-1 is an European standard.

Scope: BS 476-22 is more comprehensive than BS EN 1634-1, covering not only fire resistance but also other criteria such as durability, weathering, and corrosion resistance.

Requirements: BS 476-22 has more stringent requirements than BS EN 1634-1, including fire tests to ensure that doors and shutters can withstand the full range of fire conditions.

Test procedures: BS 476-22 has a more detailed test procedure than BS EN 1634-1, including fire tests that involve the complete door and shutter assembly, as well as tests for different types of fires.

BS EN 1634-1: The European Standard

BS EN 1634-1 is a European standard that outlines the requirements for fire-resistant building materials, including doors and shutters. It is based on the principles of the BS 476-22 standard and has been updated to reflect the latest trends and best practices in the industry.

Key Differences:

Origin: BS EN 1634-1 is an European standard, while BS 476-22 is an American standard.

Scope: BS EN 1634-1 is a more limited standard than BS 476-22, covering only fire resistance and not other criteria such as durability or weathering.

Requirements: BS EN 1634-1 has fewer requirements than BS 476-22, including only fire resistance tests.

Test procedures: BS EN 1634-1 has simpler test procedures than BS 476-22, including only fire resistance tests.

Conclusion:

The choice between BS 476-22 and BS EN 1634-1 can be a critical decision for professionals in the construction industry. Both standards have their own strengths and weaknesses, and the right choice will depend on the specific requirements of your project.

BS 476-22 is a more comprehensive standard that has a stricter test procedure, while BS EN 1634-1 is a more limited standard that has simpler test procedures.
