Sandwich panel fire documents: match the report to the proposed supply

Before comparing offers, put the requested panel and the report reference in the same enquiry. A brochure headline is not enough to show which configuration the document covers.

Core classification, finished-panel reaction to fire and assembly fire resistance are different evidence scopes. [2] The tested configuration and report application limits matter. [1]

Ask the supplier to identify the document for the offered configuration. Record mismatches and missing documents as open questions. Send those questions to the project reviewer before confirming the order. This checklist records purchasing information; it does not approve the design or state that ZY holds a particular classification.

Fictional comparison: offer A names a core material; offer B gives a finished-panel report reference. These are different document descriptions. Request the covered product and configuration for both, rather than choosing a winner from the headings.

Turn a discrepancy into a supplier question
For each report reference, write the offered detail beside the covered detail. If the product identifier, panel thickness, facing, joint or installation is missing or different, identify the exact field and ask for clarification. Record the supplier’s answer and the reviewer’s response with the same drawing revision. “Document received” and “review completed” are separate statuses; an unanswered row remains open. This is a document-control exercise, not a judgement that either panel passes or fails.
