The ECE R118 fire resistance test is a critical certification for vehicles,especially buses, coaches, and other commercial transports, to ensure materialsmeet stringent EU flammability standards. Whether you’re a material supplier,manufacturer, or OEM, understanding ECE R118 compliance is key to accessingEuropean markets. This article breaks down the test’s scope, procedures, andactionable strategies to help you achieve seamless certification.
1. What isECE R118? Scope and Legal Requirements
