Hannah Mansell says the transition to evidence-based specification is an opportunity to elevate ironmongery’s role in fire doors
For decades, the fire door and ironmongery sectors have relied on documentation varying widely in format, scope and transparency back to foundational test evidence. Certificates, Field of Application documents, Classification reports, Extended Field of Application (EXAP) assessments and hardware data sheets have often been interpreted in isolation, leading to fragmented understanding of fire door system performance. The absence of a consistent framework meant specifiers were frequently required to infer compatibility rather than verify it.
The reality is a fire door’s performance is created by interaction of components to deliver system performance, not by any single element. Both BS 8214:2026 and the ASFP Green Book (Fire Door Systems) mark a significant shift in mindset, approach and expectations.
The shift towards system-level evidence
BS 8214:2026 and the ASFP Green Book are contributing to a move away from assumption, towards specific evidence-based system verification. This invites a specification mindset shift from “information is not wholly clear; can I assume performance?” to “have I got specific test evidence and verification of manufacture consistency, change control and batch traceability to show this exact system performs in use and building conditions, and over its lifetime?”
The ASFP Green Book complements this by providing a framework for sourcing and evaluating evidence. It pulls due diligence forward, puts engagement and change control at the centre, and encourages supply chain to confront compatibility, limitations and system behaviour before decisions are locked in.
It encourages due diligence, helping designers, contractors, manufacturers and clients understand system behaviour before specifications are finalised. It supports the changing mindset as the fire door sector moves from products tested under national protocols to those tested, extended and classified under European frameworks.
An evidence-based due diligence shift should support better outcomes: reduced rework, fewer late changes, improved co-ordination and more predictable performance. When end user requirements are understood, systems are planned properly, documentation is scrutinised and decisions are approved by people who are competent to discharge them, projects run more smoothly.
Next-gen compliance
Future-proofed compliance is a live system that interfaces with the living building and evolving user needs. And the next generation of compliance will not be achieved through vague documentation. It will be achieved through demonstrable system performance, supported by transparent evidence and competent decision-making.
For specifiers evidence-led design and decision making shouldn’t be seen as a burden, but a moment of leadership. It is a chance to push back against value engineering and elevate ironmongery and access control from afterthought to critical interface.
