De weerstand wordt op Europees niveau beoordeeld via de normen EN 13123 (eisen en classificatie) en EN 13124 (beproevingsmethoden), met weerstandsklassen van EXR1 tot EXR5. Dit is een kritieke prestatie voor gevoelige locaties: energie-infrastructuur, chemische en petrochemische industrie, datacenters, ambassades, commandoposten, militaire installaties en Defensiegebouwen.<\/p>\n<p>&nbsp;<\/p>\n<h3>Waarom een gebouw beschermen tegen explosie?<\/h3>\n<p>In een benadering van fysieke beveiliging en terrorismebestrijding doet een deur meer dan sluiten of toegang controleren: zij kan een deel van het effect van een schokgolf absorberen, een risicozone compartimenteren en een strategische doorgang vrijhouden. Explosiebestendige deuren beantwoorden aan drie categorie\u00ebn dreigingen: anti-schokgolf (drukgolf), explosie in engere zin, en plasticering (lading aangebracht op of vlak bij de deur).<\/p>\n\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\n\t\t\t\t\t\n\t\t\t\t\t\n\t\t\t\t<\/div>\n\n\t\t\t\t\t\t\t\t\t<div class=\"relative\">\n\t\t\t\t\t\t<figure class=\"overflow-hidden    lg:scale-110 \">\n\t\t\t\t\t\t\t<img decoding=\"async\" width=\"360\" height=\"325\" src=\"https:\/\/www.heinen-doors.com\/wp-content\/uploads\/2026\/06\/simple_1.jpg\" class=\"w-full h-auto object-cover\" alt=\"\" srcset=\"https:\/\/www.heinen-doors.com\/wp-content\/uploads\/2026\/06\/simple_1.jpg 360w, https:\/\/www.heinen-doors.com\/wp-content\/uploads\/2026\/06\/simple_1-320x289.jpg 320w, https:\/\/www.heinen-doors.com\/wp-content\/uploads\/2026\/06\/simple_1-177x160.jpg 177w, https:\/\/www.heinen-doors.com\/wp-content\/uploads\/2026\/06\/simple_1-350x316.jpg 350w\" sizes=\"(max-width: 360px) 100vw, 360px\" \/>\n\t\t\t\t\t\t<\/figure>\n\t\t\t\t\t<\/div>\n\t\t\t\t\n\t\t\t<\/div>\n\t\t<\/div>\n\t<\/div>\n\n\n\n\n\t<div class=\"text-image full relative overflow-hidden    py-14\"  style=\"background: linear-gradient(45deg, #eef4f8, white);\" >\n\n\t\t\n\t\t\n\t\t<div class=\" container \">\n\n\t\t\t\n\t\t\t\t\t\t\t\t\t\t\n\t\t\t\n\n\t\t\t<div style=\"grid-template-columns: 100% 1fr;\" class=\"lg:grid  gap-8 \">\n\n\t\t\t\t<div class=\" \">\n\n\t\t\t\t\t<header class=\"flex flex-col \">\n\n\t\t\t\t\t\t\n\t\t\t\t\t\t\t\t\t\t\t\t\t<h2 class=\"mt-0 mb-8 \">Het normatief kader: Europese normen en internationale standaarden<\/h2>\n\t\t\t\t\t\t\n\t\t\t\t\t\t\n\t\t\t\t\t<\/header>\n\n\t\t\t\t\t\t\t\t\t\t\t<div class=\"prose text-secondary \">\n\t\t\t\t\t\t\t<h3>De Europese normen EN\u00a013123\u00a0\/\u00a0EN\u00a013124<\/h3>\n<p>Twee normreeksen bestaan naast elkaar, afhankelijk van het beoogde explosiesscenario.<\/p>\n<p><strong>EN\u00a013123-1\u00a0\/\u00a0EN\u00a013124-1 \u2014 Beproeving in een schokbuis (shock tube).<\/strong> Deze methode simuleert verafgelegen explosies met grote ladingen: van 100 tot 2\u00a0500\u00a0kg TNT op afstanden van 35 tot 50\u00a0m.
