In architectural hardware procurement, door hinges are often considered a minor component. However, industry experts and professional buyers understand that hinges are one of the core components of a door, directly impacting its service life, safety performance, and overall quality. Especially for interior door hinges, if they lack rigorous international certifications, they may fail during daily use or in emergencies, posing safety risks.
Consequently, an increasing number of engineering projects and procurement specialists insist on selecting interior door hinges that have passed CE and UL certifications. These certifications not only comply with stringent international standards but also provide reliable quality assurance for residential, commercial, and public buildings.
The CE mark indicates that a product meets the safety, health, and environmental protection requirements of the European Union market. For door hinges, the primary reference standard is EN 1935 (testing for durability and safety of door hinges). For instance, EN 1935 requires hinges to undergo 200,000 open-close cycles and demonstrate certain fire resistance and load-bearing capabilities.
UL (Underwriters Laboratories) is a renowned safety testing organization in the United States. For hinges, the UL 10C fire test is critical, assessing whether the hinge can maintain the door’s integrity and closing function during exposure to fire conditions lasting from 90 to 180 minutes. UL certification is also a mandatory requirement for engineering projects in the North American market.
In simple terms: CE certification ensures daily durability and European market access, while UL certification ensures fire safety under extreme conditions and North American market access. Hinges holding both CE and UL certifications can meet the diverse requirements of global engineering projects.
High-quality certified hinges minimize issues like loosening, sagging, and noise, extending service life and lowering long-term maintenance and replacement expenses.
Locations such as hospitals, schools, and laboratories require not only high durability but also strict hygiene and safety standards. Stainless steel hinges with both CE & UL certifications are the preferred choice.
