materials for structural steel exposed to hydrocarbon pool fire conditions with rapid temperature rise.<span class=\"inline-flex\" data-state=\"closed\">\u200b<\/span><br \/>Industry explanations note UL 1709 reaches roughly\u00a0<strong>1,093\u00b0C within 5 minutes<\/strong>\u00a0and then stays near that level, creating severe thermal shock that demands engineered passive fire protection systems.<span class=\"inline-flex\" aria-label=\"Complying with Fire Standards - Insulation Outlook Magazine\" data-state=\"closed\">\u200b<\/span><\/p><p class=\"my-2 [&amp;+p]:mt-4 [&amp;_strong:has(+br)]:inline-block [&amp;_strong:has(+br)]:pb-2\">UL 1709-based testing and certification are commonly referenced in petrochemical and offshore contexts because the exposure is

id=\"3-what-bs-476-measures-typical-building-fire-expos\" class=\"mb-2 mt-4 font-sans font-semimedium text-base first:mt-0 md:text-lg [hr+&amp;]:mt-4\">3) What BS 476 measures (typical building fire
