BS 476 Part 22

What Is BS 476 Part 22?

BS 476 Part 22 is a key standard within the UK's building safety regulations that specifies methods for testing the fire resistance of non-loadbearing elements of construction, such as doors, shutters, and various types of ducts and dampers. This standard is instrumental in determining how these elements will perform in the event of a fire, ensuring they meet the necessary safety requirements to protect building occupants and property.

Why BS 476 Part 22 Certification Matters？

Proven Safety Standard

Long-established and trusted in global construction, confirming that fire doors can effectively resist flame penetration and heat transfer during fire incidents.

Regional Acceptance

Still widely referenced in regions adopting UK-based codes, enabling market access and compliance for fire door products outside the EU framework.

Certification Scope

The scope of BS 476 Part 22 covers the testing procedures for assessing the fire resistance of any non-load-bearing components of a building when exposed to specific heating and pressure conditions as detailed in BS 476 Part 20. The standard includes detailed observation of the specimen’s behaviour under test conditions, including the manner and timing of failure, if applicable. This comprehensive approach helps in understanding the effectiveness of building components in fire conditions.
