EI60 identifies a tested fire-resistance period of 60 minutes for both integrity and insulation. It is not a material label and does not transfer automatically from the leaf to a different frame, hardware set, size or wall construction.
Why This Must Be Specified Opening by Opening
A project requirement is useful only when it identifies the opening, intended use, performance target, tested configuration and party responsible for approval. Generic catalogue language cannot resolve different risk zones, wall conditions, hardware sets or operating logic.
Project Specification Checklist
- Read the letters: E covers integrity against flame and hot gases; I adds a limit on heat transfer to the unexposed side.
- Verify the standard: Identify the test and classification standard required by the project and authority.
- Match the assembly: Compare leaf, frame, seals, glazing, hinges, lock, closer, dimensions and opening direction with the report.
- Check the wall: Use an approved supporting construction and installation method, including anchors and perimeter fire stopping.
- Control changes: Do not substitute viewers, access-control hardware or closers without confirming that the evidence permits them.
Evidence to Review Before Purchase
- Fire test and classification reports
- Scope and permitted variations
- Label and traceability method
- Installation and inspection instructions
Match every report to the exact product proposed. Check dimensions, opening direction, leaf and frame construction, hardware, seals, anchors and supporting wall. Record any difference and obtain formal acceptance before production.
Common Failure Modes
The most common failures are choosing a rating by habit, approving a certificate for another configuration, changing hardware after testing, ignoring the wall interface and leaving commissioning until handover. An opening schedule and evidence matrix expose these gaps while they can still be corrected.
What to Include in the RFQ
Send the destination, project type, door marks, quantities, finished openings, wall construction, required standards, hardware and access-control schedule, finishes, delivery stages and documentation list. This lets the supplier respond with a configuration rather than an unsupported headline claim.

FAQ
Is a supplier declaration enough? No. Request evidence that covers the proposed complete assembly and have it reviewed by the responsible designer and authority.
Can hardware be changed after approval? Only when the evidence or responsible authority permits the substitution. Treat every change as a configuration review.
